I am not happy with the state of this in 16.04: I do 'sudo do-release- upgrade' in the anticipation of getting 18.04.1, and I get instead
'Checking for a new Ubuntu release Please install all available updates for your release before upgrading.' even if I have just run sudo apt-get update; sudo apt-get upgrade. I am *not* in the habit of rebooting my machine after updates: oak@oak:~$ uptime 13:01:09 up 260 days, 18:06, 12 users, load average: 20.53, 20.91, 21.40 but the message does *not* suggest that the reason it won't let me do- release-upgrade is that there is a reboot pending. Indeed, even after a reboot and sudo apt-get update; sudo apt-get upgrade I get the same message. oak@oak:~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION="Ubuntu 16.04.5 LTS" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1797209 Title: do-release-upgrade should block release upgrades in some circumstances To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1797209/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
