It looks like this issue has been happening multiple times. Apparently it doesn't happen if we try to update a clean install. And the common denominator seems to be that lxd is installed and some containers are running.
So, I've tried the following: - setup a bionic VM with an encrypted storage: single disk with 2 partitions - created a striped zfs pool using the encrypted storage - initialized lxd to use the zpool - started multiple containers - distro upgrade from bionic to focal (with the containers active) - distro upgrade from focal to groovy (with the containers active) But, even with all of the above, I wasn't able to reproduce the problem: the distro upgrade went smooth and completed without errors. Considering that lxd moved from being a deb package to a snap, I was wondering if this could be part of the problem. However during my tests (upgrading from bionic to focal) lxd actually moved from deb to snap and I couldn't see the problem. So, it's either a rare set of conditions, or the problem is gone now with the recent Ubuntu releases. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1841377 Title: package zfsutils-linux 0.8.1-1ubuntu9 failed to install/upgrade: installed zfsutils-linux package post-installation script subprocess returned error exit status 1 Status in zfs-linux package in Ubuntu: Confirmed Bug description: During upgrade from 19.04 to 19.10.
