Playing around with Linux Mint, noticed during OS install it gave an option to encrypt the user's home directory. I skipped it, but now want to try it. I'm trying to ecryptfs-migrate-home -u UserName but I keep getting errors about files being open, which makes sense I suppose since i'm logged in as that user.
I only have this one user on my VM, is it not possible to encrypt a home folder while you're logged in? could i just encrypt the whole drive?
Just playing around here, so not worried about data loss, but would rather not have to waste another hour reloading the OS due to user error

I wonder why files are open. :-)

You'll need to create another user with admin privileges and encrypt the original user's home directory logged into the new account.

Do it as root - or single user.

I tried and successfully installed eight Unixes OSs this week, trying to get LM17 to "accept" and boot a FreeBSD, or TrueOS on sdb.
It did not go well. The partitioning and install went well, but I think grub2 "hates" ZFS and or UFS (FreeBSD and TrueOS native formats).

Any who's after that "party", I had to get back to work by Monday, so I fired up my install of 17.1, used LVM with encryption but decided additionally encrypting /home wasn't necessary as the entire thing is on an Encrypted LVM, the only way it will "go", AFAIK is during install else, it's all manual and I'd rather not mess any more with breaking stuff, so I opted for it during install.

It is the simplest method, IMO. During install.

Just sayin'

Thanks, i ended up doing it in single user mode. I agree, definitely easier to do it during install.
