I'm going to take a shot in the dark and ask if the root file system
is XFS. It doesn't take too much googling to find out that XFS has a
reputation for reporting ENOSPC when there seems to be more than enough
room left. Apparently, it can do so as a result of fragmentation problems
even though the disk as a whole has lots of space --- for one cautionary
example see this thread:
https://www.spinics.net/lists/linux-xfs/msg22856.html
typo-ishly titled "ENSOPC on a 10% used disk". It looks like the XFS crew
installed a fix for the underlying bug ... but that thread is from 2018
and you're running a 2015 Ubuntu release.
Or, to cut to the chase: maybe updating to a less hoary kernel would help.
If you are stuck with this Ubuntu release for some reason, consider using
a less bleeding-edge-at-the-time file system.
