I've tried to re-install everything using

for package in $(apt list --installed | grep -P ".*(?=/)" -o); do sudo apt install --reinstall -y $package; done;

and got this error

[you-nerd (you-nerd)]

was iirc just running

sudo apt update
sudo apt upgrade

for the daily/latest build

[you-nerd (you-nerd)]

had the error pop up again, this time on a fresh install of the daily build from 2023-04-10: d355b7bf12aac278d72652c38f68d7a2db2c8e0e44d57cd614d4b3a3024efb2a *lunar-desktop-amd64.iso

Steps to reproduce here:

Use ubuntu studio installer to install *-wallpapers & *-menu; *-lowlatency, *-lowlatency-settings, *-performance-tweaks & *-pipewire-config. Lastly, use ubuntu studio installer to install *-audio, and let it enter standby mode via 1 hour timeout.

Then resume from standby and login to see that the installer has completed installing and that this bug has been identified with the 'An error has occurred' prompt.

[you-nerd (you-nerd)]

error popped up once again, this time on a fresh install of the daily build from 2023-04-11: 03fbe48602860c82f2eda6daffa8b86f771ef7978991bd29d94e92d193c93613 *lunar-desktop-amd64.iso

Was running the following in terminal:

sudo apt update
sudo apt install ubuntustudio-installer
y

[error occurs as packages are being downloaded]

I've encountered the same crash during every release upgrade I've tested from Kinetic to Lunar. I've opened a bug (2015919) with an ubuntu-release-upgrader task so that we can look at surpressing the crash message during the upgrade process.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubuntu-release-upgrader - 1:23.04.5

---------------
ubuntu-release-upgrader (1:23.04.5) lunar; urgency=medium

  * Update the autopkgtests for the deb2snap changes.

[Daniel van Vugt (vanvugt)]

I'm not sure how many people that workaround will help given this is the top crash in Ubuntu 23.04. I don't imagine it's during release upgrades in all cases.

I tested an upgrade without the DistUpgradeQuirk in play and I did not receive a crash report from tracker-miners. Thanks for fixing it!
