This seems to be a valid one. An upgrade from 8.0.21-0ubuntu0.20.04.4
to 8.0.22-0ubuntu0.20.04.2 will likely trigger a timeout that will
prevent apt upgrade from finishing, because it requires an internal
server upgrade that can take several minutes (apparently depending on
the database size; I couldn't reproduce it locally with an empty db). I
subscribe Ubuntu Server, but still marked the bug as Incomplete since
I'd like to confirm my suspicion that the reporter does have a sizeable
MySQL database.
This concern sounds like
https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1882527
Although based on the reporter's reply, perhaps in this case it wasn't
caused by the database being large, and was something else.
Hey Robie,
Thanks for the reply. I had a gut feeling that some of you might know a
similar issue. Indeed, it seems like they're related; during my
investigations I also noticed the TimeoutSec parameter in the service
file, and thought that the next step of the investigation could start
there.
I left a question to the reporter asking whether they have a big
database. If they do, then I (or someone) can try to populate the test
database with dummy entries and try to replicate the scenario. Let's
see.
The bug submitter commented that he didn't have a big database and that
the system load wasn't particularly high during the upgrade. Moreover we
have a new almost identical bug:
LP: #1901956 - (New) [mysql-8.0] - package
mysql-server-8.0 8.0.22-0ubuntu0.20.04.2 failed to install/upgrade:
installed mysql-server-8.0 package post-installation script subprocess
returned error exit status 1
I asked if there is a big database in place or an unusually high system
load, but I think we have an actual issue here. What has to be
understood is if the bug is with the "server upgrade" operation taking
to long when it shouldn't, or "just" with the timeout, too low for an
operation that can take several minutes for good reasons.
