Updater reverts repositories to default

[cassidea]

Describe the bug
Mintupdate reverts repositories to Ubuntu and Mint defaults which are extremely slow in my case (<20kB/s)

To Reproduce

• be on Mint 22
• select mirrors for Mint and Ubuntu
• start update to 22.1
• cancel update when packages are downloaded
• check repositories in mintupdate

Expected behavior
Configured repositories should be used

Distribution:

• Linux Mint
• LMDE
• Other (please specify)

Software version:
7.0.5 and previous
I started the update process with a previous version when the problem occurred. Then mintupdater got updated to 7.0.5. probably due to the canceling of the update process. But the error still exists.

Reason is, that the updater copies a file with the default repos from /usr/share/mint-upgrade-info/{codename}/official-package-repositories.list to /etc/apt/sources.list.d/official-package-repositories.list, see

mintupdate/usr/lib/linuxmint/mintUpdate/rel_upgrade_root.py

Line 57 in c540de3

subprocess.run(["cp", sources_list, "/etc/apt/sources.list.d/official-package-repositories.list"])

I guess some sed magic could do the trick, too.

I just learned that this is expected behavior, see https://forums.linuxmint.com/viewtopic.php?p=2417609#p2417609
