Comment 5 for bug 224303

addditional info I found:

kex@xpc:~$ G_DEBUG=fatal_criticals update-manager
current dist not found in meta-release file
current dist not found in meta-release file

(I upgraded one day before 8.04 was released)

What was peculiar is that when starting from command line, like this, sudo actually worked.

So I tried to update dist, but it said it is up to date already. And crashed when exiting:

kex@xpc:~$ sudo G_DEBUG=fatal_criticals update-manager --dist-upgrade
sudo: unable to resolve host xpc
