Quick update as I have tested a number of install options on a Thinkpad 460s.
1 - Secure Boot, UEFI, no Wifi - install works and all good after apt-get update,upgrade 2 - No Secure Boot, UEFI, no Wifi - install works and all good after apt-get update, upgrade 3 - Same as 2, enabled Wifi, but no Update during install - Fails This one was interesting as I assumed the issue was part of the upgrade at install scripts... not so. 4 - Legacy Bios - install USB will not even boot. Likely unrelated and an issue in setup. Also the mentioned AskUbuntu question has been flagged as attracting low quality answers by some dumba$$ algorithm so cannot be update without 10 rep points. The unfortunate downside of automated SPAM. Regardless a networkless install seems to be a work around for now, and upgrading after seems to work fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1673247 Title: package snapd 2.23.1 failed to install/upgrade: trying to overwrite '/etc/apparmor.d/usr.lib.snapd.snap-confine', which is also in package snap-confine 2.23.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1673247/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
