I think this is a strong possibility. The system is hosted on an old Xen hypervisor (although, I've never had this problem before, updating other VMs from 18.04 to 20.04).

I still was able to finish the update successfully, nevertheless. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903367 Title: package lxd (not installed) failed to install/upgrade: new lxd package pre-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1903367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
