I can't disable proposed updates

[Albert Cutrona]

Hi!!

Accidentally I've enabled proposed updates in development section but now I can't disable it. I've rebooted the laptop but the issue isn't fixed.

Regards!!

Albert, a reboot shouldn't be necessary. Did you get a "reload" prompt when you un-ticked the "Pre-released updates" box?

Did you click "Reload" or "Close"?
Is that box still ticked?

We need a little more information from you in order to establish whether you have encountered a bug or need help in disabling the proposed repository.

Hi, thanks for your response.

Yes, I've reload as the pop up suggests, and after reloading, the box is still ticked. I've deleted the source "proposed" in etc/apt/sources.list.d, sudo apt-update, and the box isn't ticked anymore.

If you need I can try to reproduce it.

Best regards!!

Status changed to 'Confirmed' because the bug affects multiple users.

Just noticed the same thing in my Xubuntu 16.04.
I do not recall enabling proposed at all, so I'm baffled.

I have now removed the proposed.list and proposed.list.save from /etc/apt/sources.list.d folder by commenting the files with a # and will see what that does.

[ajgreeny (ajg-charlbury)]

OK, that worked as expected, and now when I go to Software Sources from the Xubuntu menu I can enable and disable the proposed repos without a problem as I expect to be able to do.
This is baffling!

[Brian Murray (brian-murray)]

Were in /etc/apt/sources.list.d/ did you find proposed enabled? What was the name of the file and what were its contents?

[ajgreeny (ajg-charlbury)]

I found the two files, proposed.list and proposed.list.save in /etc/apt/sources.list.d folder and both of them had the same content:-

deb http://gb.archive.ubuntu.com/ubuntu/ xenial-proposed universe main multiverse restricted

Neither file had that one line commented out with a # as I would expect. I removed those files and now I can enable and disable the proposed repos and if enabled the /etc/apt/sources.list file contains a line as shown above as I expected.

[ajgreeny (ajg-charlbury)]

Just as a trial I have a few minutes ago restored the proposed.list file to /etc/apt/sources.list.d/ which is where I originally found it, and once again I am not able to disable the proposed repos from software-sources GUI. Whatever I do, the tick in the selection box of the Developer Options tab stays firmly selected.

Removing that proposed.list file once again as I did before has once more disabled the proposed repos.

So it looks as if something has added those proposed.list files to /etc/apt/sources.list.d/ with no reference to me, and I am completely baffled about what has been done, by what process, and why it happened.

I do have several ppa repos enabled, but I always have done so without this ever occurring in the past, so I believe that is unconnected.

[ajgreeny (ajg-charlbury)]

Hopefully a final comment about this from me, with a suggestion about how to restore the packages that you don't want from "proposed" back to stable repository versions.

With some help from another Ubuntuforums member, 1fallen, I was given this info page from askubuntu
http://askubuntu.com/questions/768849/how-to-reverse-proposed-channel-package-upgrade
which I followed and successfully managed to get my machine back to where I thought it was before this surprise discovery of "proposed" being enabled.

[Brian Murray (brian-murray)]

I haven't dug all the way into the code but I suspect the Developer Options tab and the Updates tab only hanlde -updates, -security, and -proposed to exist in /etc/apt/sources.list not in a different file in /etc/apt/sources.list.d/.

Additionally, I'd expect -proposed to appear in the "Other Software" tab of software-properties.

I'm still really curious where the proposed.list file came from. Maybe try "dpkg -S /etc/apt/sources.list.d/proposed.list".

[ajgreeny (ajg-charlbury)]

The output from
"dpkg -S /etc/apt/sources.list.d/proposed.list"
is now what I expected,
"dpkg-query: no path found matching pattern /etc/apt/sources.list.d/proposed.list"
as I have now disabled the proposed repos so that is no help.

I did not think to look in the "Other software" tab of software-properties, but as far as I can remember the proposed repos were not there, and I think I would have noticed as I go there quite often as I have several ppa repos for which I sometimes check out repo addresses.
.
Anyway, problem over for me now as I am back to the standard repos versions of everything with no problems so I don't see any way that I can help any further.

[Expired for software-properties (Ubuntu) because there has been no activity for 60 days.]

[ajgreeny (ajg-charlbury)]

I forgot about this bug, but I later realised that the problem was due to my installation of the OS from a daily cd version of the ISO file from http://cdimage.ubuntu.com/xubuntu/xenial/daily-live/pending/xenial-desktop-amd64.iso.zsync rather than the normal download site. I did not realise that the version from there has proposed repos enabled
Apologies for not reporting this find before, but at least I now know what was the cause.
