it cannot be reproducible for other, since you did not mention which
steps you exactly made. It's good that you updated your repositories,
but you did not mention how you updated the repositories. Did you use a
GUI, did you do it by command line? The best practise is to run from
command line...

...don't follow instructions that don't try to troubleshoot, but just
try to tinker and consider to use the official Ubuntu command line
package management tool apt first. IOW run

sudo apt update

Are there any warnings and/or error messages?
If so, copy and paste the command and it's output to an email.
If not, continue with

sudo apt full-upgrade

are there any warnings and/or error messages?
If so, copy and paste the command and it's output to an email.
If not, continue with...

...trying to install GIMP. Btw. for what purpose do you need the
libgegl-dev package?

FWIW there at least is no version conflict, see

libgegl-dev (0.3.4-1ubuntu2)

libgegl-0.3-0 (0.3.4-1ubuntu2)

sudo apt update
sudo apt install gimp

Copy and paste the command and it's output. The output will show us the
reason for the conflict, so we could tell you what to do, to get rid of
the conflict.

If you copy a command and it's output, then please don't (auto-)wrap the

Any reference for that claim?

Xubuntu is an official Ubuntu flavour, so EOL of 16.04 is April 2021,
see https://wiki.ubuntu.com/Releases.

Not all repositories are maintained in the same way, see
https://help.ubuntu.com/community/Repositories, but that doesn't mean
that the dependency chain is allowed to be inconsistent.

As you can see, it's possible to install gimp and libgegl-dev. Please
follow my troubleshooting advises.
