    How To Clean Up Ubuntu

Some simple ways to free up space on Ubuntu
Remove Unnecessary Packages and Dependencies

apt-get autoremove

Clean Apt Cache

Check the amount of apt-cache on your system
du -sh /var/cache/apt

Remove all apt-cache from your system
apt-get clean

Uninstall Pakcages You Never Use

Remove specific packages
apt-get remove package-1 package-2

Remove packages and dependencies that are no longer required
apt-get autoremove

Remove Old Kernels

List your current version of linux kernel
umame -sr

Check how many linux kernels versions are installed
dpkg -l | grep linux-image | awk '{print$2}' | wc -l

Check which linux kernels versions are installed
dpkg -l | grep linux-image | awk '{print$2}'

Find the linux image number and set the LINUXIMAGE, for example linux-image-3.13.0
LINUXIMAGE=linux-image-3.13.0

Find the linux image extra number and set the LINUXIMAGEEXTRA, for example linux-image-extra-3.13.0
LINUXIMAGEEXTRA=linux-image-extra-3.13.0

Find the lowest version number and set the STARTNUM, for example 50
STARTNUM=50

Find the version number before the current version and set the ENDNUM, for example 100
ENDNUM=100

Automagically delete all the old kernel versions
for i in $(seq $STARTNUM $ENDNUM); do apt remove --purge $LINUXIMAGE-$i-generic -y; done
for i in $(seq $STARTNUM $ENDNUM); do apt remove --purge $LINUXIMAGEEXTRA-$i-generic -y; done
