Describe the issue you encountered

gdb -q
Traceback (most recent call last):
  File "~/.gef-.py", line 86, in <module>

I was able to install inside gdb last week, but now neither inside gdb nor outside gdb installations are working. What could be the reason?

Do you read the docs and look at previously closed issues/PRs for similar cases?

You can also provide a Dockerfile if you prefer

Additional context?

You'll need to either update gdb or downgrade gef. The compatibility matrix needs to be updated. You should be able to go to a release from mid-2022 at least.

Should be fixed by #1061 (at least on 18.04)
