apt clean → cleans the packages and install script in /var/cache/apt/archives/ (removes all stored archives in your cache)
apt autoclean → cleans obsolete deb-packages, less than clean (removes all stored archives in your cache for packages that can not be downloaded anymore (thus packages that are no longer in the repo or that have a newer version in the repo))
apt autoremove → removes orphaned packages which are not longer needed from the system, but not purges them, use the --purge option together with the command for that.
apt --purge autoremove → remove config files and (more important as it cleans dead subdirectories from the documentation tree) entries from /usr/share/doc.

Boot Partition Clean Up (Ubuntu/Debian)
# Check Current Kernel Version
sudo uname -r
# Example output: 5.4.0-64-generic
# As you see on image in my case – 5.4.0-64-generic is current kernel. Other older kernel versions can be deleted.
# List Old installed Kernel images:
sudo dpkg --list 'linux-image*'|awk '{ if ($1=="ii") print $2}'|grep -v `uname -r`
# Your output will something like:
linux-image-5.4.0-39-generic
linux-image-5.4.0-42-generic
linux-image-5.4.0-54-generic
linux-image-5.4.0-64-generic
# To cleanup boot partition in Ubuntu uninstall old kernels with apt command one by one:
sudo apt-get purge linux-image-5.4.0-39-generic
sudo apt-get purge linux-image-5.4.0-42-generic
sudo apt-get purge linux-image-5.4.0-54-generic
# Remove no longer used dependencies:
sudo apt-get autoremove
# Update GRUB:
sudo update-grub
Change Console setup
# For italian keyboard:
sudo dpkg-reconfigure console-setup
