Possibly the 20.04.4 live system is also involved, because to my knowledge setting a proxy via Settings/Network does not normally make any changes to /etc/apt/apt.conf (i.e. you are not prompted for a sudo password after setting a manual proxy in Settings/Network).
So I'm guessing the 20.04.4 live system made the apt.conf change since apt requires it. (Note: some earlier versions of Ubuntu live systems did not make the apt.conf change automatically; we had to do it manually whenever we had to use proxies.) In any case, whatever cleared the manual proxy setting from both user accounts ideally shouldn't do that. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1986850 Title: Manual proxy is partially cleared on 20.04 => 22.04 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-upgrader/+bug/1986850/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
