Yesterday I was editing some videos on Kdenlive. It crashed and a prompt showed that I have very few disk space. Seeing this I analyzed the disk and found that /tmp folder was acquiring most of the space on the partion (my linux partion is of around 42GB of which 19GB remains free). I inquired upon Google about /tmp folder and found that it is place where temporary files are stored and it is cleaned at every boot.
I may have delete some of those files manually.
Now at each boot, Ubuntu ask me for a new Default Keyring Password whenever I open Chromium-Browser, i.e. my Default Keyring Password resets on every boot.
I would also like to know why this happened. Thanks in advance.
P.S.: I didn't checked on Mozilla Firefox, but think that it would give same result.
