After running Disk Usage Analyzer on the file system, I am looking for ways to remove unneeded files on my Live USB.
Firstly, is there anything I can do about the files in the casper archive? For example, I noticed that there exists a directory
/rofs, which I'm sure stands for read-only file system, the one stored in the read-only
casperfile, so I can't removing anything in it. Specifically, I removed LibreOffice yet /rofs/usr/lib/libreoffice takes up 222 MB of precious storage, as does Thunderbird and a bunch of other things.
What can I clear regarding the apt program files.
/var/lib/apt/liststakes up 115 MB, and
archivesdirectory) is 139 MB. The
/var/cache/aptfolder is made up of several ~35 MB files, and I don't know if they are all necessary:
ubuntu@ubuntu:/var/cache/apt$ du -ah 4.0K ./archives/partial 0 ./archives/lock 28K ./archives 4.0K ./typescript 34M ./srcpkgcache.bin 31M ./srcpkgcache.bin.ifDvIA 34M ./pkgcache.bin.3IHVIK 32K ./pkgcache.bin.h2Zwz7 36M ./pkgcache.bin 133M .
I already clear browsing data regularly when I use chrome, so I don't think I have to deal with that much. However, I see that there are cache folders for other programs, and I wish to know if there is a safe way to remove the cache.
Generally, my question revolves around why I have only less than 300 MB on my 4.0 GB USB thumb drive when I only use it for browsing and simple development in python.
Your help is appreciated.
