Sorry for the late reply. This is very strange, the error is in code that really shouldn't be executing in this case. If you try 20.04.3 you should be able to start a shell after the install fails which will at least make debugging more possible.
My only guess is that somehow subiquity thinks your block devices are unreasonably small (so somewhat related to https://bugs.launchpad.net/subiquity/+bug/1943609, although subiquity would have to think _all_ disks are small to hit this in your case I think). ** Changed in: subiquity (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939015 Title: [Ubuntu 20.04.2 Server] Autoinstall max() arg failure with cloud- config LVM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/1939015/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
