@WinEunuuchs2Unix : I wish the person that did a selective kernel purge script, the one I pointed you to on launchpad, would let me try it. As far as I can determine, without actually trying it, it should be pretty good. He is hung up about getting money for it, and we have argued the point to death, over a period of many many months.
For myself, I want to be able to selectively purge kernels, and almost always newer kernels than the default, because I am always working with the latest release candidate series. Also, when I do a kernel bi-section I end up with about 15 kernels just for that.
@ Serge, I do not recall if there is a post on askubuntu about it. The person enetered a couple of launchpad bugs. wait a sec for links...
@WinEunuuchs2Unix : now I just wait until I don't need an entire series anymore and then do this: sudo apt remove linux-headers-4.9.0-bi?? and sudo apt purge linux-image-4.9.0-bi?? for example.
@serg, because I have so many. Currently ~~65 on my main test server.
@DougSmythies I've begun rewriting the script for low-latency and rc-stock kernels but I still have that display-auto-brightness project on the go as I mentioned earlier. It will take some time....
@DougSmythies Fair enough... however apt-get purge linux-image..." and apt-get purge linux-headers...` are the accepted solutions in all the Q&A's I've read.
@luk3yx also, you removed OP's command-line output and pasted it into pastebin. That's not exactly considered a good idea for edits. It's ok onyour own posts,but not on other people's
ii linux-image-4.11.0-041100rc1-generic 4.11.0-041100rc1.201703051731 amd64 Linux kernel image for version 4.11.0 on 64 bit x86 SMP ii linux-image-4.11.0-rc1-stock 4.11.0-rc1-stock-217 amd64 Linux kernel, version 4.11.0-rc1-stock rc linux-image-4.4.0-62-generic 4.4.0-62.83 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP rc linux-image-4.4.0-63-generic 4.4.0-63.84 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
@DougSmythies Anyway I've just modified the code on my end to remove -generic however it breaks the file size calculations and error messages pop up. It would still allow you to remove your stock and low-latency kernels if you do that though.
@WinEunuuchs2Unix : I know you mentioned you have other pressing stuff to do. I just got excited earlier today when I saw your question. I am fine using my current method.
@DougSmythies The original concept was 99% of the people were using -generic kernels and hiding the phrase on each line made it easier to read and less redundant. I'll whip up a version that includes all non-generic kernels for you. The non-gui version will take more research time for me though.
@luk3yx I would say it can be considered as destructive edit - removing information user provided and putting it into pastebin. I was searching meta just now for a post on this topic, but I cannot find it. Actually, this would be a good question. Go ahead and ask
I have attempted to edit this post, however the edit was rejected.
After asking on the Ask Ubuntu general chat room, one of the kind users said that it is considered a destructive edit to move command line edits to a pastebin, unless it is your own post.
Why is this?
@WinEunuuchs2Unix you mentioned in your question that the duplicate doesn't provide easy solution. Is synaptic not easy ?
Oh, I see. You're asking for a method without having external tools installed
Guys, what do you call websites, where like construction companies or businesses make project proposals, and then the manufacturing companies make bids/offers ?
@WinEunuuchs2Unix : Seems very good. There is some problem purging linux-image-4.11.0-rc1-stock thou. I think it tried, but it is till there. So I tired again, but got some error. Other 7 or so kernels deleted just fine. Note: This is a VM, and I made a clone to work on, so that I can easily go back to the start point (~15 kernels) and try again. (Currently, not sure how to copy and paste from my VM to show you the error. Might have to continue tomorrow.)
@DougSmythies I'll have to install Kernel 4.11 rc1 and test it myself. I've yet to install Kernel 4.10.1 so I'll do both at the same time and report back. It could also be apt-get purge doesn't see the links to images in /boot when you compile your kernel manually. I could try that later but I need to read up on how to make a kernel first.
My company's system administrator is asking for our passwords for an ISO audit and my VP IT operations support says it's mandatory for ISMS (ISO27001).
Can someone confirm if this is true?
@DougSmythies I completed installation and purging of Kernels 4.10.1 and 4.11.0 rc1 and encountered similar problems to your rc-stock. I've updated the answer with what to do: askubuntu.com/questions/892076/…
@WinEunuuchs2Unix : I never use apt-get install to install kernels. I only use "sudo dpkg -i linux-header_bla_bla.deb linux_image_bla_bla.deb" and never have an issue. Sometimes I do see something about "The link /vmlinuz is a damaged link", but it has never actually been a real issue. I would never ever do "sudo rm /boot/*4.10*".
I re-installed the 4.11rc1 headers, then booted the kernel, just to prove it wasn't messed up or partially removed. Then I booted again into 4.4.0-66-generic and removed 4.11 manually: sudo dpkg -P linux-headers-4.11.0-rc1-stock linux-image-4.11.0-rc1-stock.
@DougSmythies Yes I use "sudo dpkg -i *.deb" to install the two header files and image file too. "apt-get install" was a super bad typo on my part. The rm-kernels script will also use "sudo apt-get purge linux-image-4.11.0-rc1-stock linux-headers-4.11.0-rc1-stock" so there should not be any errors as well.
@DougSmythies I've taken out the "experimental kernel" section of the answer until we can nail this one down. I can change the order in the script to remove headers before images and to use "apt" instead of "apt-get" if necessary.
@WinEunuuchs2Unix : Same result as first test. linux-image-4.11.0-rc1-stock is not even appearing in the list as something it (meaning apt, when it asks for yes or no) wants to remove, even though I selected it (meaning from the radio button list). The header file does appear, and is removed.
@DougSmythies I had the same problem with "linux-image-4.10.1-041001-lowlatency" not appearing in apt-get purge even though the headers showed up. I should be able to fix your problem by fixing my own.
@DougSmythies No worries because I can reproduce the problem on this end I can figure it out. Probably not until tomorrow though it's already 11pm here and my brain starts to fade.
@DougSmythies I found the bug and updated the answers. The second last line of the script had to be replaced with this: ` echo "dummy- $list" | xargs bash -c '</dev/tty apt-get purge "$@"'` For some reason xargs was dropping the first parameter passed to apt-get so I put in a dummy first parameter.
@muru probably you know this already, but last night SE re-ran the conversion to catch the hostmar links - 2000 posts were updated. I am just mentioning it because I'm still finding them in the etherpad (seems to be just the ones already marked i so far, so maybe it's deliberate)

@WinEunuuchs2Unix : There is still an issue with the selective kernel removal script. For some types of kernels, there are two header packages an "all" one and a architecture (i.e. 32 bit or 64 bit, and low-latency or generic) one. It is only removing (or purging) one of them. For example it removes the generic but not the all. For my 4.11-rc1 example, there is only one header package and it purges that kernel entirely.
@WinEunuuchs2Unix : Is it O.K. with you if I go onto the bug report I referenced and mention that someone is working on a selective kernel removal script? That guy claims to have addressed all of these issues, including having something that works on headless servers, via SSH. My objective would be to get him to give up on his quest for money, and let me test his version.
@DougSmythies Feel free to link to any of my Q&A anywhere in Stack Exchange. The more people that try out the scripts the better they become with more input.
@DougSmythies How did you discover the header all files were left behind but the generic files were deleted? For example I used apt list command and grep to see what is still installed. I had used the script to remove (purge) 4.4.0-59 and 4.4.0-62. However I had left 4.4.0-63 untouched. When I run apt list I get:
rick@dell:~$ apt list --installed | grep 4.4.0-59
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
───────────────────────────────────────────────────────────────────────────────
rick@dell:~$ apt list --installed | grep 4.4.0-62
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
───────────────────────────────────────────────────────────────────────────────
rick@dell:~$ apt list --installed | grep 4.4.0-63
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
So for 4.4.0-63 we see two headers and two images installed. For the others that were deleted nothing shows up. Do I have to refine my search somehow?
@WinEunuuchs2Unix : Note before: I have been cleaning up my clone VM, so not much garbage is left. So, I was down to just a few kernels left. In the below listings notice the header files for -53 and -64 are still there, but shouldn't be.
doug@desk-dev:~$ dpkg -l | grep linux-im ii linux-image-4.4.0-51-generic 4.4.0-51.72 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP ii linux-image-4.4.0-57-generic 4.4.0-57.78 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP ii linux-image-4.4.0-66-generic 4.4.0-66.87 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
I have the residual "all" files too from when the script was broken last night:
$ dpkg -l | grep linux-head
ii linux-headers-4.10.1-041001 4.10.1-041001.201702260735 all Header files related to Linux kernel version 4.10.1
ii linux-headers-4.11.0-041100rc1 4.11.0-041100rc1.201703051731 all Header files related to Linux kernel version 4.11.0
ii linux-headers-4.4.0-63 4.4.0-63.84 all Header files related to Linux kernel version 4.4.0
I'll reinstall 4.10.1 and 4.11.0 rc 1 today and retest with the new script version.
@DougSmythies Now I see the problem. In version 1 it would do "apt-get purge linux-headers-www.x.y-z*" In version 2 when support was added for "-generic" it became "apt-get purge linux-headers-www.x.y-z-generic" so the "all" was missed. If I revert back to first purge format then "all", "generic", "lowlatency","rc1-stock", "amd64" and "386" headers will ALL be deleted for "linux-headers-w.x.y-zzz".
@DougSmythies Someone could have linux-headers-4.4.0-63, linux-headers-4.4.0-63-generic and linux-headers-4.4.0-63-lowlatency. When purging linux-headers-4.4.0-63-generic we don't automatically want to remove the "all" file linux-headers-4.4.0-63 because that would break linux-headers-4.4.0-63-lowlatency. Am I right in this theory?
^^^ Any of you apt-get purge linux-headers... experts feel free to jump in :)
@Seth Thanks for that. What do you think of the idea of a bounty badge though? i like it because almost 20% of my rep points come from bounties but will others not be so keen on the idea?
I suggest two new badges:
Greedo - first bounty earned (bronze)
Boba Fett - earned 2000 rep through bounty (silver)

Now, the big question: do I be lazy today, and just spend the day at work watching TV series/youtube/whatever , or spend some time coding and working on my side project, or try to read textbook/do truth table computation/write lab report draft ?
Frankly, I don't want none of these. All I really want is to sleep. Curl up with my pillow and listen to ASMR
eh, I should write myself a script that rolls dice for me
@WinEunuuchs2Unix I'm safe for today. 4 in my cigarette box, and I work until 3 pm. Only 3 hours left to go, and I smoke only 2 during work hours on Sundays. Already had one, so that's 3 for me for the road
And even if I don't have any at home, I still have plently of pipe tobacco
@DougSmythies OK code has been modified to handle multiple headers when -generic and -lowlatency are installed. Make sure you are running this version with comment "Modified: March 12, 2017" : askubuntu.com/questions/892076/…

Hmmm I need one upvote to take me from the bottom of 10 people with 1 vote (like me) to get to my own list of 2 upvotes hint: askubuntu.com/questions/2793/…
@WinEunuuchs2Unix, couple concerns with your Zenity script for kernels.
First, it's only going to remove kernels that were installed through apt, which is not a fair assumption to make. Some people use compiled or custom kernels, which don't register themselves through the standard package system.
Hopefully anyone with the skill to compile their own custom kernel can look at the bash source and modify it to their needs of deleting extra stuff here and there.
In any respect my script does the same as the canned packages with 498 upvotes and does it faster. If the issue comes up where my script doesn't work for an individual I'd be happy to modify it to address their fringe environment.
@KazWolfe OK I rewrote the introduction taking out update-grub is only called once and put in the selling point that native Ubuntu bash is used so people that didn't install kernels with apt or dpkg can modify the source more easily :D
I'm a bit confused around apt-get and apt. Is apt an replacement of apt-get or just a similar tool? The reason why I'm asking is because it seems like most of the basic functionality in apt-get is also available in apt but there doesn't seem to be an apt equivalent to apt-get purge. What I like t...
Well, as far as emails go, there's really not that many people that send emails , if ever. I had my email in the profile for a while. Over years, most of the people who contacted me only found me through github , or when I voluntarily gave them my email
@Seth I see you closed the Ubuntu One question and noted it on the etherpad list - are you checking them all? Would it be easier for you if I do something different to making them not clickable? If I can do anything in a better way, please let me know...
@DougSmythies Sounds good. BTW @KazWolfe has concerns the script won't work for some custom kernel scenarios and I told him you were testing such a beast.
@DougSmythies Kaz mentioned that kernels can be installed in a non deb way. What i mean,.is that he is right and your case isnt the only that may need to be addressed
