fwrite(): Write of 2123 bytes failed with errno=28 No space left on device
you dont have more space...
try : rm -rf /var/logs
and rm -rf /tmp/*
then try again
And configure maximum size (and optionally oldest log age) of your log with
journalctl (or other log manager used by your OS) to prevent it happens again.
