Your file system seems to be full, can you check following

df -h

I have checked but which files to delete? i have no idea

Can you establish a connection via SSH? That way you could copy all the information directly from the SSH terminal and not have to do screen prints. Also, this simplifies the way to copy the following command, which we can use to find out what large files you have on your system.:slight_smile:

du -a / --exclude /mnt/usb_drive | sort -n -r | head -n 20

Ok, after I have found out, delete them?

let’s have a look first. Or you know what you do and you are 100% sure.
