I set up a laptop with linux mint cinnamon within the last two weeks, and while trying to install The Sims 4 today I got a message that the hard drive was out of space. I have installed nothing so far except for Steam, and tools to get The Sims 4 running. I see that 131gb is taken up by .ecryptfs and a web search turned up this thread however I used the utility that was suggested with the same result. Then OP says multiple reboots have cleared up the issue. I am on reboot 4 now with no such luck.
Is it safe to delete this? Is it something with timeshifted?
Full disk encryption should be an option during setting up the partition. iirc you beed to select lvm or something similar there.
