Stuck with 20.7.5

[bebef]

Hi everyone!

I'm stuck with 20.7.5. Whenever I search for updates, most of the time I get "Timeout while connecting to the selected mirror.". When I click "Check for updates" again, I might get "There are no updates available on the selected mirror." or "The package manager is not responding.".

I have explicitly configured/tried several mirrors, all with the same result.  :(

Internet connection itself doesn't seem to be the issue, as I have no issues connecting to the mirrors (via the diagnostics tools in interfaces).

Cheers

try update from console ;-)

I tried the console, with the same result. Then I had a suspicion: my dynamic prefix IPv6 is broken (again), so I disabled IPv6 and it immediately worked!
