Public bug reported:
Fully updated locally, multiple reboots before/after.
Ubuntu 16.04 Xenial
libecryptfs1 - 111-0ubuntu1.1
Using kubuntu GUI (possible cause?)
Problem:
Encrypted home directory as part of install process.
Logging into GUI as normal user.
Switch to alternate terminal (ctrl-alt-F2) - do not log out of GUI
Log into same normal user in that terminal.
Log out of that terminal.
Switch back to GUI interface (ctrl-alt-F7)
Open terminal.
ls on home directory
Shows results of:
. .. Access-Your-Private-Data.desktop .bash_history .cache
.ecryptfs .kde .local .Private README.txt .viminfo
Logging back into alternate terminal results in home directory being
remounted.
Expected result (any/all of the following):
1) When at least one open(local) login is still active, leave encrypted
directory mounted.
2) Notify user that home directory was unmounted
3) Notify user when attempting to access home directory that it is
unmounted/not accessible
4) Allow actively logged in user(pre-verified) to remount drive.
5) Notify user logging out that drive will be unmounted.
What happens:
No notifications that this happened occur. Attempting to perform any actions
that require access to home directory fails. As this was my first install with
the encrypted home directory, wasn't sure why my home dir was suddenly missing
when I hadn't logged out, just died. I thought initially this was a failure
with the encryption certificates, and I'd just lost everything. Was looking
into options to roll back encryption and any way I might be able to recover
lost data when I logged into terminal again and it was there. Cross verified
with GUI(still logged in) that home dir was now accessible.
Also, I notice if I have multiple terminals open(local or remote), and
exit any/all but one, the home directory remains logged in. The moment
the last terminal is logged out, the directory is unmounted, which
results in the GUI being unable to access that directory. Again, this
may point to a Kubuntu usage instead of just Unity(default?). However,
I would still expect this to work the same, regardless of what desktop
environment is being used.
Work-around: Remain logged into at least one terminal will allow home
directory to work again. This probably should only be temporary,
allowing time to do necessary saves/closing and log out of GUI/terminal
to log back in.
