I can't get the 16.04 LTS to 18.04.1 LTS upgrade to work, I'm running server.
My current version:
lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.5 LTS Release: 16.04 Codename: xenial
However despite 18.04.1 being released on the 26th of July, at present on the 31st I'm still being informed that there is no new release?
/etc/update-manager/release-upgrades file is:
# Default behavior for the release upgrader. [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the release that immediately succeeds the currently-running # release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that this option should not be # used if the currently-running release is not itself an LTS # release, since in that case the upgrader won't be able to # determine if a newer release is available. Prompt=lts
And the output of
Checking for a new Ubuntu release No new release found.
Update manager core is already installed:
sudo apt install update-manager-core Reading package lists... Done Building dependency tree Reading state information... Done update-manager-core is already the newest version (1:16.04.13). 0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
Note that this question is distinct to the one here Should I be offered the option to upgrade to 18.04.1? as that question deals with a GUI/desktop based situation whereas this specifically addresses the issue from a terminal / server angle.
