I found it to be the fastest and most effective way to use the find command and exclude specific folders. That is using the “prune” option:
find /FOLDER_TO_SEARCH_INSIDE -path /FOLDER_TO_EXCLUDE -prune -o -name 'NAME_OR_PATTERN_TO_SEARCH_FOR' -print
That’s it, Enjoy!

We need to cleanup the following:

docker system prune
It might take some time.
Enjoy a clean environment!

To know which packages are supported and which are not, for how long and whether the community or canonical are the ones who support it, just run:
ubuntu-support-status
It will give you this sample output:
Support status summary of '$HOSTNAME': You have 211 packages (15.4%) supported until April 2021 (Community - 3y) You have 1431 packages (74.0%) supported until April 2023 (Canonical - 5y) You have 2 packages (0.1%) supported until April 2021 (Canonical - 3y) You have 2 packages (0.1%) supported until January 2019 (Community - 9m) You have 24 packages (0.9%) that can not/no-longer be downloaded You have 254 packages (9.5%) that are unsupported Run with --show-unsupported, --show-supported or --show-all to see more details
To get more detailed info, add –show-unsupported, –show-supported or –show-all. You could of course use grep to help in filtering.
Just Some Techie Notes!
