[Trisquel-users] Running out of space in partition 1

[aferyok]

My Partition 1 has 15GB, with 2.6GB still free, about 83% full.  I have not  
installed any software other than what I am required to.  Each time I do an  
update, I have a little bit less space left.
I have had this computer for at least two years (perhaps four).  Do I need to  
manually delete log files with sudo?  Do I need to leave my computer on  
overnight?  How do I fix this?  Thank you.
