Bug#931649: apt: Please advise users on moved or EOL'd repositories
Package: apt
Version: 1.9.1
Severity: wishlist
Dear APT Maintainers,
When a repository is no longer available APT does tell that but gives
little help to the user who the issue could be resolved:
root@teaching-dolphin:~# apt update
Ign:1 http://archive.ubuntu.com/ubuntu artful InRelease
Ign:2 http://security.ubuntu.com/ubuntu artful-security InRelease
Err:3 http://security.ubuntu.com/ubuntu artful-security Release
404 Not Found
...
Reading package lists... Done
...
E: The repository 'http://archive.ubuntu.com/ubuntu artful-backports
Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is
therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user
configuration details.
root@teaching-dolphin:~# do-release-upgrade
Checking for a new Ubuntu release
Your Ubuntu release is not supported anymore.
For upgrade information, please visit:
http://www.ubuntu.com/releaseendoflife
On the other hand if the user knows about do-release-upgrade or can
update /etc/apt/sources.list manually the system can be upgraded to a
still supported version or changed to use the new location of the
repositories if they moved.
Please consider printing hints in well known cases to help users
getting out of the situation by either suggesting upgrading the the
system or redirecting them to the new repository URLs.
Cheers,
Balint
