I woke up to a red exclamation mark on my computer. It warned I had only 800k of disk space remaining in /home . I went into terminal and did " df -h " to confirm this.
/dev/sdb5 825G 783G 13M 100% /home
That is 42gb that remains. Did Ubuntu go on strike while I was sleeping and refuse to use this? Is the4re a logical explanation? Or did I just discover an error with Ubuntu 18.04?
