If you installed GIMP from outside the repos at any time before the upgrade, it would make sense that it would be removed for compatibility reasons. Also, any and all installations from outside the official repos are not supported.
The reason GIMP 2.10 was not included in 18.04 is due to the fact that GIMP 2.10 breaks MyPaint 1.2 due to a library compatibility issue. Since MyPaint 1.2 and GIMP 2.8 are included in the Ubuntu Studio flavor, it would have broken the entire flavor. Additionally, GIMP 2.10 was released after the feature freeze. So, until MyPaint releases a 1.3 version, 18.04 will be stuck with GIMP 2.8. Ubuntu 18.10 will contain GIMP 2.10, and as such MyPaint was dropped from Ubuntu Studio until the bug is corrected.

Since this bug and workaround involves installation from outside the official Ubuntu repos, this bug is invalid. ** Changed in: gimp (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1788943 Title: after upgrade to xubuntu 18.04 from 16.04, gimp fails to launch...
