I am attempting to upgrade from 22.04 to 24.04(.01) for months (sporadically tried 2-3 times in September, once mid October and once yesterday) and still the same issue happens: the upgrade tool passes all the steps until it should start downloading and installing new/upgraded packages, which fails due to no network available.
Luckily enough it is able to rollback all the previous steps (which includes removing plenty of applications) and I am left with no networking. Luckily, a restart is all that is needed to resolve this.
Speaking about resolving (pun intended), I have noticed that resolvconf or some stuff around dhcp is on the remove list. I suspect this is the reason why networking stops working and no new packages can be downloaded.
How to fix this? Is this expected to happen or is it a bug? How is that nobody else experience(s|d) the same issue? 24.04.01 was released end of August and I have noticed some people had issues upgrading soon after that, but they do not seem to be related to my issues and no new issues are reported since early September.
Here is some upgrader tool output:
