How to clean /var/cache?
Solution 1
Polipo, a web caching program may store a lot of data in an on-disk cache.
One way to clear this up is to issue the command sudo polipo -x
- this will cause polipo to clear the local disk cache.
Solution 2
Method 1:
sudo apt-get autoclean
sudo apt-get autoremove
Method 2:
Launch your bleachbit as root user : no space in disk; sudo apt-get clean not working
Solution 3
The most powerful of all commands to clean the cache for command line users is of course
sudo apt clean
Which will also delete all the cached files.
Solution 4
Try cleaning ubuntu unnecesarry files using bleachbit. It is a tool that will help you clean your cache, temp files, cookies and it has other features also...
To install it:
sudo apt-get install bleachbit
Solution 5
It sounds so obvious, and yet chances are you haven’t done this.
By default Ubuntu keeps every update it downloads and installs in a cache on your disk, just in case you ever need it again.
This is useful if you regularly add and remove apps, find yourself needing to reconfigure/reinstall a specific package, or simply have a poor connection.
But the flip side is that the apt package cache can quickly swell to several hundred MBs. This command tells you how big your apt cache is:
du -sh /var/cache/apt/archives
To clean the apt cache on Ubuntu simply run the following command.
sudo apt-get clean
The apt clean command removes ALL packages kept in the apt cache, regardless of age or need. If you’re on a slow, capped or intermittent connection you may want to consider skipping this step.

When I woke up this morning, I found my root had filled overnight
du -hx --max-depth=1 / 132M /boot 4.0K /media 16K /lost+found 16M /root 702M /lib 4.0K /OLDHOME 8.2G /usr 73M /etc 4.0K /srv 11M /sbin 4.0K /selinux 8.0K /.config 4.0K /cdrom 4.6G /var 181M /opt 4.0K /mnt 9.3M /bin 4.0K /lib64 14G /
The space is used by /var/cache/polipo (2.7G). How can I clean this up safely?
I tried restarts=>didn't work
Used bleachbit=>the space is not detected in the cleanup previewPS: I did rm -rf youtube inside /var/cache/polipo and it freed up 2G space. Dunno if it was safe though
