Tried to run in / but ran out of space for logs.

There's a 1GB Swapfile:

              total        used        free      shared  buff/cache   available
Mem:           990M        121M         88M         22M        781M        624M
Swap:          1.0G        101M        922M

What could be causing the 6GB bloat?

    Could you post output of: sudo find / -type f -size +1000M -exec ls -lh {} \; Oct 25 '19 at 19:49
  • Does rebooting fix the issue? I've had a similar problem where I deleted a file but the space wasn't marked as usable until I rebooted. Oct 25 '19 at 20:04

    Thanks! I'd found linux header files clogging the space. Have removed them with sudo apt-get autoremove.

The bulk of the usage was in /usr/src.

Apparently there were lots of linux header files in there amounting to 3GB!

Did the following:

sudo apt-get update
sudo apt-get -f install (cause there were some unmet dependencies)
sudo apt-get autoremove

ubuntu@:~$ sudo apt-get autoremove

After this operation, 3214 MB disk space will be freed.

After removing those header files, usage is down to 3.3GB. With 1GB swap that's around 2GB of various files which I think is quite reasonable.
