If you’re a Ubuntu user who finds themselves with an ugly message like this one day when running a apt-get update,
No apport report written because the error message indicates a disk full error
you may have thought you’ve run out of disk space and run the command,
but then found you had plenty of space free. Well maybe you do have plenty of bytes free but what about inodes? They’re effectively a limitation of the number of files you can have in a filesystem.
