Public bug reported:
In a focal LXD container, I was replacing python3.7 with python3.8. At
the end, I ran autoremove to get rid of the last python3.7 pieces, and
this happened:
$ sudo apt autoremove
sudo: setrlimit(RLIMIT_CORE): Operation not permitted
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
libfreetype6 libpython3.7 libpython3.7-dev libpython3.7-minimal
libpython3.7-stdlib python3.7-minimal
0 upgraded, 0 newly installed, 6 to remove and 55 not upgraded.
After this operation, 46.9 MB disk space will be freed.
Do you want to continue? [Y/n]
