I have Xubuntu 16.04 LTS installed:
# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.5 LTS
Release: 16.04
Codename: xenial
And I thought by now that the LTS upgrade to 18.04.01 would be possible, due to the announcement last month, however:
# do-release-upgrade
Checking for a new Ubuntu release
No new release found.
Is there a delay in releasing 18.04 LTS through the do-release-upgrade
route?
Try
the
-d
flag at the end of the command, it will upgrade to the current development version. Which might or might not be 18.04.
