Dear Prof. Gavin, After invoking all the commands you have listed I have come to know that *.cache *folder contains 12 GB of space. .cache folder contains the followings;
event-sound-cache.tdb.bb916188e665483abe367841b820014a.x86_64-pc-linux-gnu gstreamer-1.0 pip ubuntu-report evolution ibus thumbnails update-manager-core fontconfig ibus-table thunderbird yelp gnome-desktop-thumbnailer mesa_shader_cache tracker3 Is anything removable from this folder to recover the space? with regards, On Mon, 29 Apr 2024 at 00:58, Gavin Abo <gabo13...@gmail.com> wrote: > The operating system /var log files I typically would not remove.
