How to clear the APT cache - The Linux Notes

Clear the APT cache to reclaim disk space used by the downloaded packages.

Inspect APT cache configuration

Check out the current APT cache configuration using the following command.

$ apt-config dump | grep "^Dir\( \|::Ca\)"

$ apt-config dump | grep "^Dir\( \|::Ca\)"

Dir "/";
Dir::Cache "var/cache/apt";
Dir::Cache::archives "archives/";
Dir::Cache::srcpkgcache "srcpkgcache.bin";
Dir::Cache::pkgcache "pkgcache.bin";
Dir::Cache::Backup "backup/";

Dir "/";
Dir::Cache "var/cache/apt";
Dir::Cache::archives "archives/";
Dir::Cache::srcpkgcache "srcpkgcache.bin";
Dir::Cache::pkgcache "pkgcache.bin";
Dir::Cache::Backup "backup/";

Remove every package from the cache

Perform a simulation of the whole process.

$ sudo apt-get clean --dry-run

$ sudo apt-get clean --dry-run

Del /var/cache/apt/archives/* /var/cache/apt/archives/partial/*
Del /var/lib/apt/lists/partial/*
Del /var/cache/apt/pkgcache.bin /var/cache/apt/srcpkgcache.bin

Del /var/cache/apt/archives/* /var/cache/apt/archives/partial/*
Del /var/lib/apt/lists/partial/*
Del /var/cache/apt/pkgcache.bin /var/cache/apt/srcpkgcache.bin

Remove retrieved package files.

$ sudo apt-get clean

$ sudo apt-get clean

Remove outdated packages from the cache

$ sudo apt-get autoclean --dry-run

$ sudo apt-get autoclean --dry-run
