[Bug 2076019] Re: package firefox (not installed) failed to install/upgrade: new firefox package pre-installation script subprocess returned error exit status 10

[Amin Bandali]

Hello, I tried upgrading an Ubuntu 22.04 VM (using libvirt, which is
qemu-based) to 24.04 but was not able to reproduce this error; the
upgrade went through just fine. Is there perhaps anything unusual about
your system/setup?

Also, if you still have access to the system in that state, I wonder if
trying restarting the following snapd services before attempting to
upgrade may help:

sudo systemctl restart snapd.seeded.service
sudo systemctl restart snapd.service
