Isn't this dead?
@Terrance Nevertheless I think we should and do.
 
I was just wondering because Canonical dropped it from the Ubuntu ISOs a long time ago.
@dessert You wanna give the link or should I?
 
@Terrance Don't just give the link, write a short answer with the workaround, that's useful information for AU! Of course it's you who should have the rep.
 
12:13 AM
@dessert Really doesn't matter to me. You did the work finding the issue. =)
 
@Terrance But I want to go to sleep now, it's 01:14 here! :D
 
@dessert =) Alright, if no one has written anything by the time I get home, I will write up an answer for it.
 
@Terrance That's the spirit, I'll leave a short comment for the OP to know. Get home safe!

Q: How to install rEFInd for DIY multiboot USB

EraserPencilI intend to create a dualboot persistent usb. I'd like to try creating a USB where I can boot macOS High Sierra and WIndows 10. From what I understand of LVM, I can create 2 VG, 1 APFS and 1 NTFS. This would allow me to boot into Windows10 on a PC and Windows10/macOS on a Mac. I know workarounds ...

@SergiyKolodyazhnyy Regarding this: The only other reason i could think of might be the many offspring's from base Debian which would make it difficult for apt-get to know them all and their respective correct sources.list lines. so they skipped to include such functionality.

A: Cannot upgrade unsupported version of Skype for Linux (v5)

Nicholas OdicohIn 32 bit linux, make skype a "higher" version: sudo sed -i 's/4.3.0.37/8.3.0.37/' /usr/bin/skype It replaces the version number in the binary for a higher one to work around the forced incompatibility. Make sure that you have the same version 4.3.0.37 by calling skype --version or update the com...

:O
 
@dessert Wiat! What? hes applying sed changes to a binary file?
probably a bad idea ...
 
@Videonauth To change the version number!
What do we do when encountering a possibly valid answer that's just a bad idea?
 
@dessert downvote it, it will then be sent automatically to the review que for low quality as soon it hits a treshhold for downvotes
if i got this right
maybe comment on it why this is a bad idea:)
 
@Videonauth Interesting, that sounds very reasonable! I feel like this has to be documented anywhere, where does EliahKagan and Co. take all his knowledge?
@Videonauth Could you do that please? I will look biased as the accepted answer is from me…
 
in fact if there would be a number sequence in the binary lets say 41320337 this would get cought by s/4.3.0.37/8.3.0.37/ too
remember the sed substitute first field is a regex
 
8:28 AM
omg you're right, it's not even a correct sed expression
 
and . can be anything
 
\. would be a dot
wait no
he did escape the dots, it's fine
well not fine, but at least not totally wrong ;)
 
yep i guess the \ got eaten by the page because not properly code formatted
still, a bad bad idea
might work, but might as well kill the binary
 
escaping the dots in the replacement section is unnecessary though (but not harmful)
 
except youre using r/.../.../
which would make both fields a regex
if i remember this correctly
I'd rather advise the use of a hex editor instead of sed as this could go horribly wrong. And please if you stick to this answer use -i.bak so at least a backup of the file is made before the change. — Videonauth 1 min ago
 
8:34 AM
there's no r/…/…/ in sed AFAIK… what would be the use of a regex in the replacement?
horrible layout, good content ^^
I also use sed.sourceforge.net/sed1line.txt a lot, it's like an extended cheat and tldr
 
there is an r/ but i was wrong, long time not used sed tbh.
> r filename

Reads text file a file. Example:

$ seq 3 | sed '2r/etc/hostname'
SCrolling 2 minutes to get the the edit button, cant we have those buttons at the top please ? askubuntu.com/q/981159
 
9:07 AM
@Videonauth Shoot first, read questions later. ;D
 
Tbh editing this question is a pain and since he used quotes for formatting all the lines are off now.
 
@Videonauth sed "s/['\"]//g" ;)
 
sed 's/^\>\ //'
still would leave the lines in their messed up format
since making something a blockquote inserts newlines if used on a long block of text

Of course you can preserve /home in an Ubuntu reinstall and you're done, but in this case Ubuntu is being installed over Mint, not over Ubuntu. I don't know if it would work that way, because I've never tried it. — karel 5 hours ago
@karel Is it in installer? and even if the /home is under root partition? I haven't seen such in any versions yet!

@Anwar Your comment led me to a solution to the question: askubuntu.com/questions/56051/… Someone's going to answer that question for sure unless somebody dupes it to that link and I can't CV it because I've already retracted my CV at that question.
 
@karel Do you need somebody to CV? ;)
 
1:13 PM
Anybody please mark this as a duplicate of that – OP said he tried it, but after a comment war it turns out the second answer is exactly what he needs. sigh Unfortunately I already used my CV and retracted it later…
 
@dessert done
 
@Videonauth thanks!
Why was this deleted? oO

Q: Using wmctrl with zenity prompt causes budgie-wm segmentation fault

TomI'm attempting to write a bash script that switches between workspaces with some dialog prompts along the way. I'm running Ubuntu 17-04 with Budgie remix. When using wmctrl or zenity separately, they both work fine. Put them together however and budgie window manager crashes with a segmentation ...

 
do you have an actual answer for that?
 
1:24 PM
not a clue
but I'm sure it's a bug → off-topic
 
@dessert I already CVed wrong and then the OP edited the question and I retracted it, so yes I need a volunteer to CV that question because I can't CV it.
 
@karel Sorry, which question again? I got confused here… Is it a duplicate?
 
1:49 PM
@dessert It's this question: askubuntu.com/questions/981541/… however it has already been correctly duped and closed, so it's OK now.
 
@karel OK :)

A QI was trying to create bootable USB of Ubuntu 17.04. First, I erased everything from the pen drive and then started to copy using sudo dd if=path_to_ubuntu_image of=/dev/rdisk2 but it is taking around 5 hrs to complete the process. I read previous answers about speeding up it using rdisk instead ...

Any ALSA experts around? I'd like to have my volume adjustments to the center channel persist after a reboot.
But as it stands now, the volume always resets to 100% after a reboot.
^--- that channel
Master volume is preserved across reboots.
 
@NathanOsman Not an expert, but you can easily script it using amixer get Center and amixer set Center <value>.
 
Good idea - thanks.
 
Oh, there's also
alsactl store
> store saves the current driver state for the selected soundcard to the configuration file.
maybe not quite right :P
equivalent:
alsactl restore
> restore loads driver state for the selected soundcard from the configuration file. If restoring fails (eventu‐
ally partly), the init action is called.
