GIMP will not start, GEGL error
Solution 1:
I had to add the repo again. Then run:
sudo apt install ppa-purge && sudo ppa-purge ppa:otto-kesselgulasch/gimp
sudo apt-get install gimp
After that gimp was able to install and start normally.
Solution 2:
When you say
I've tried removing and reinstalling GEGL.
you’ve been updating the standalone GEGL package. What GIMP needs is the libgegl package, which is not included in ppa:otto-kesselgulasch/gimp for some reason. I have submitted a bug report to the PPA maintainer.
Solution 3:
I had remove gimp and gegl with
sudo dpkg --remove gegl
sudo dpkg --remove gimp
And reinstalled again to get it work.
Solution 4:
I received this error, too, & tried all the solutions to resolve it. Now, when I try to launch GIMP, I see it trying to launch in the "Activities" bar, but then it disappears & the app fails to launch. I've purged it from my system & have tried reinstalling it, but so far nothing has worked. I still cannot get the app to launch in 20.04.
