I've had this issue:
# do-release-upgrade -f DistUpgradeViewNonInteractive Checking for a new Ubuntu release Get:1 Upgrade tool signature [819 B] Get:2 Upgrade tool [1240 kB] Fetched 1241 kB in 0s (0 B/s) authenticate 'bionic.tar.gz' against 'bionic.tar.gz.gpg' extracting 'bionic.tar.gz' MarkInstall libpam-cap [ amd64 ] < none -> 1:2.25-1.2 > ( libs ) FU=1 No candidate ver: linux-image-4.4.0-131-generic No candidate ver: linux-image-4.4.0-135-generic No candidate ver: linux-image-extra-4.4.0-131-generic No candidate ver: linux-image-extra-4.4.0-135-generic No candidate ver: linux-signed-image-4.4.0-131-generic No candidate ver: linux-signed-image-4.4.0-135-generic # echo $? 1 Then it worked after I ran: apt-get autoremove Not sure, though, whether that was the issue... I'd rather blame that had something to do with the network/mirror. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1787712 Title: 16.04 to 18.04 do-release-upgrade fails with "Command terminated with exit status 1" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1787712/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
