How do I clear the cache created by running apt-file update?
Also, is there a way to see how much space the cache is currently using?

apt-file purge

Purge the user cache. An apt-file update will be needed before a search can be performed on the user cache. If the user cache doesn't exist, the system-wide cache can be used for user searches.

Purge

Clear "Contents-" files from the apt-file cache directory. If you receive any errors listing or searching, it's a good idea to perform a purge and then an update.

To delete the system wide cache use:

sudo apt-file purge

related directories:

 ~/.cache/apt-file
/var/cache/apt/apt-file

    I'm not sure when, but at some point the purge action was removed. For example it is present in Ubuntu Trusty 14 but not in Ubuntu Focal 20 – Jet Blue Aug 10 '20 at 03:55
  • Try removing cache files using sudo rm . Some thing like given on the same page http://manpages.ubuntu.com/manpages/focal/en/man1/apt-file.1.html. – Ajay Aug 10 '20 at 05:28

    Neither of the two directories you shared are present in my system (Focal). Perhaps the new version of apt-file shares the cache info with apt. This line in the docs makes me think so: "The apt-file command relies on the APT configuration. Notably, the default configuration makes apt fetch Contents files by default during a call to apt update." – Jet Blue Aug 10 '20 at 21:22
  • I think this answer is not valid for Ubuntu since it does not support purging in its apt-file version. – Thomas Mar 26 '21 at 09:20
