Problem
After upgrading to Ubuntu 20.04 form 18.04, I wasn’t able to start GIMP 2.10. The message was in the same format as that in a related Ask Ubuntu question, except that the version numbers were greater.
I attempted installing the package gegl
, which was irrelavant to the problem.
Analysis
I found the answers mentioning the package libgegl
helpful.
$ dpkg -l | grep gegl
ii gegl 0.4.22-3
amd64 Generic Graphics Library Test Program
ii libgegl-0.4-0:amd64 1:0.4.18+om-0ubu18.04.18~ppa
amd64 Generic Graphics Library
ii libgegl-common 1:0.4.18+om-0ubu18.04.18~ppa
all Generic Graphics Library - common files
Despite deletion of ppa:otto-kesselgulasch/gimp
by ppa-purge
, that leaves a
trace in /etc/apt/sources.list.d
.
