Ask Ubuntu General Room

Let me guess, respect each of them

Basically it is the same as what i asked

for URI in URI1 URI2 URI3 ; do writeToFile $URI;done

@Serg I guess in that case the first one you write has a higher priority, or the others are discarded

@kos YES =) great =D

?.archive.ubuntu.com ???

@kos, wait

This would be correct:

`deb us.archive.ubuntu.com/ubuntu wily main
deb it.archive.ubuntu.com/ubuntu wily-updates universe
deb us.archive.ubuntu.com/ubuntu wily-security main
deb it.archive.ubuntu.com/ubuntu wily-security universe`

@kos ^^^

@A.B. What happens in that case by the way? The first one has a higher priority?

10:12 AM

For your script? @kos

For your script, there is no priority.

@A.B. No, for apt-get. Seems a bit random to add mirrors like that, I mean, I suppose it changes apt-get's behavior

@kos No, all is fine. main uses us.archive, main and security uses us.archive, universe updates uses italy and security too

Looks crazy, is perhaps not useful, but valid

@A.B. Yeah, I suppose in that order though. Ok, I guess I'll have to store mirrors as well. :@

@kos @Serg @xiaodongjie new rule added (11) Don't change the protocols, e.g. https, http, tor, ...

@A.B. yes.

10:22 AM

@A.B. those are part of URI , they won't be changed

@Serg Yes, correct, ok

thank you.

10:57 AM

@xiaodongjie I have nuked my sources.list with echo | sudo tee /etc/apt/sources.list and one repository added with sudo apt-add-repository universe After that sudo ./apt-add-update enable updates

% cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily universe

yes, let me update the script now.

@A.B. I think it's becoming a bit too complicated. I think for now I'll just post an alternative script where you have to specify the protocol and the mirror, even if I won't get the bounty, I think it will be useful to somebody (I'll be using it myself from now on)

stuck again

@kos What is complicated?

with the mirrors?

If the script can check lsb_release , it makes it much easier . . . . if it has to respect all the suites even for the other releases, then it has to generate both trusty-security and wily-security . . . .

A: How to read and write to Ask Ubuntu from command line?

11:10 AM

@A.B. It's not that you can't do it, the problem is it's actually a program: every entry become multiple in an exponential way, you have to multiply each protocol found by each mirror found by each entry found; that excluding entries already present and splitting and rewriting semi-duplicate entries keeping track of the protocol and the mirror. To do things right it's a bit of work

(a bit=a lot)

Actually there is a way easier way, but you have to know Python (which I don't): going through the source code of software-properties-gtk and create a front-end to the inner functions it uses to add distributions; that way you have a perfect mirror of what it does in the command-line.

I have a question on mounting a specific folder of a partition and I found a related answer askubuntu.com/q/205841/294611 but I want that folder to be mounted with rw and rest with ro

@kos I'm not sure. protocol and server and path = URI

there is nothing to multiply

Pandya

For our meta site, I think the tag on-topic should be synonyms of/under scope.

@A.B. please check again the code in my answer.

I think that it'll work very well.

It can work with empth sources.list file.

@A.B. default?

can you explain more detail?

@A.B. Here: chat.stackexchange.com/transcript/message/25708888#25708888 if you have another protocol elsewhere (even if it uses one of the mirrors alredy present) in a another source that means you have to parse each protocol found, each mirror found and write a number of entries equal to the result, otherwise it doesn't fit the requirements of respecting the present protocols and the present mirrors.

Good morning folks!

@ByteCommander Good morning my friend ! :)

@A.B. OK, here's a new paste. The scratchPad.sh will be appending the sources to the file, just like the previous script has been doing. The output to the console right now is what will go into the file. It's just a testing phase right now.

paste.ubuntu.com/13514049

As you can see, I have in /etc/apt/sources.list a source for wily , and some sources for trusty. The output respects both

It also respects the URI's for local server, mirrordenver and archive.ubuntu.com

Basically that's a nested loop where I generate string "deb URI suite components"

@kos hello

@A.B. +1 from me askubuntu.com/q/700860/228051

@A.B. So for each URI rewrite one entry for the distribution to be enabled containing all the enabled components? And I think I'm forgetting something here, but that itslef leads to duplicate lines; see here: paste.ubuntu.com/13514116

@GeoMint o/

good point @kos

12:16 PM

@kos can you please comment on my output in the paste ?

paste.ubuntu.com/13514049

am I getting somewhere close ?

@ByteCommander tox broken ?

@Serg From what I understood, only distributions for the release should be enabled. Beside that, that output in that specific case is fine. Have you tested how it behaves in more complex situations?

@kos I minimized the sources.list file so it is easier to read. But with more complex sources.list it seemed to work fine . . .depends on @A.B.'s judgement

@Serg For example what happens if you use the part before <command> [...] here as /etc/apt/sources.list?

Byte Commander

@cl-netbox Nope, just forgot to start it once again! ;D

If it was broken, you'd have heard me rant about it.

@kos: I thought it was, but it seems that it is happening almost everywhere and all the time, I just hadn't noticed before.

@ParanoidPanda Almost everywhere all the time is not the same as only in specified places all the time, that means (99%) that the keyboard is failing.

@Serg Well, congrats on that. Seems to be working fine. Maybe I'm overcomplicating things.

@kos I think you've considered this problem much more systematically than most of us . . . .

Which is good

user136984

@kos: No, that's what I mean, it's happening all the time in specific places, there is never a time when it stops in those places nor starts in any other new ones seemingly.

12:50 PM

OK, i need to go to sleep

@Serg Not so much in this case, if it's easy it's easy. My brain is full so I'd better think about it again later. :D

@kos yeah, we still have 4 days before bounty is due

@ParanoidPanda Ok, but have you tried the other keyboard in those places where it doesn't work? What happened?

take some rest, clear the mind, and just keep on asking A.B. questions to get at what he actually wants

The only think i need to know now is default case

Q: How to mount specific directory of a partition with read and write permission and rest as read-only

@Serg Anyway I was thinking of something else, which I think would be way more useful: specifying the mirror and the protocol as arguments. If we have to take care of situations that are that complex, is unlikely that there's a predictable correct result that we can infer from the already present sources, it's more like guessing or patching everything to make sure we get what we want. And duplicating entries in an unuseful way.

Q: PHP cannot create directories or write files (Ubuntu 14.04)

I have transferred an existing PHP application from a Red Hat server to Ubuntu. The upload functionality of the app is no longer working due to PHP being unable to write to the selected directory. I modified the directory to 755 www-data:www-data but this still does not work.

ubuntu permissions php chmod

o_O

@kos personally, I think for 99% of the cases , it's sufficient to edit sources.list just like the GUI version does. Write a line or delete a line . . . such protocols as tor are added by advanced users in cli anyway . . .

@kos: No, I have to remove the cake from the other keyboard before I can use it as a reliable comparative... :P

@ParanoidPanda Being serious for a moment, you can do whatever you want, but why not testing the other keyboard. I just don't understand that. It's the most reasonable thing you could do, yet you seem to be refusing to do that for no apparent reason.
