When APT is used as a bf(dselect(8)) method, bf(clean) is run automatically.
Those who do not use dselect will likely want to run code(apt-get clean)
from time to time to free up disk space.

+dit(bf(autoclean))
+Like bf(clean), df(autoclean) clears out the local repository of retrieved
+package files. The difference is that it only removes package files that
+can no longer be downloaded, and are largely useless. This allows a
+cache to be maintained over a long period without it growing out of
+control.

+All command line options may be set using the configuration file, the

Fix; attempt to correct a system with broken dependencies in

means using dselect or dpkg --remove to eliminate some of the offending
packages). Use of this option together with -m may produce an error in

Help; display a helpful usage message and exits.

dit(bf(-m, --ignore-missing))
Ignore missing packages; If packages cannot be retrieved or fail the
integrity check after retrieval (corrupted package files), hold back
those packages and handle the result. Use of this option together with
--f is discouraged.

dit(bf(-q, --quiet))
Quiet; produces output suitable for logging, omitting progress indicators.
