sudo apt install lvm2 But I wasn't using LVM and had no volumes set, so it wasn't risky for me.

I have no idea why lvm2 fails to install/upgrade though... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882179 Title: package lvm2 2.03.07-1ubuntu1 failed to install/upgrade: installed lvm2 package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1882179/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
