The debian packages are typically in /var/cache/apt/archives, ready to be used for a reinstallation.
If you are short on space, you can safely delete these:
sudo apt-get clean
To delete only unused .deb package files (deinstalled, older versions etc) use:
sudo apt-get autoclean
To delete orphaned packages (which aren’t required or used), use:
[sourecode language="shell"]
sudo apt-get remove --purge `deborphan`
[/sourcecode]
deborphan is a distinct command that lists the orphaned packages.Advertisement
