I just installed Ubuntu 15.04. During installation, I enabled both full disk encryption and home directory encryption. I then proceeded to install several applications.
While installing these with apt-get, I got the following message:
Broadcast message from root@my-machine (Thu 2015-06-11 20:46:43 EDT):
Password entry required for 'Please enter passphrase for disk ubuntu--vg-swap_1 (cryptswap1) on none!' (PID 7634).
Please enter password with the systemd-tty-ask-password-agent tool!
Please enter passphrase for disk ubuntu--vg-swap_1 (cryptswap1) on none!
This message came up fairly randomly, averaging once every minute or so. A couple times it happened twice in a row, with virtually no time between (I suppose there's a chance I typed my password wrong). The installation process appeared to pause each time (until I enter my passphrase), though I'm not convinced it was fully paused.
To me, it appears that my machine isn't saving the decryption passphrase, which I think it should do at boot (when I decrypt the disk) or at login time (when I decrypt the home folder). Any idea how I can coax it into doing this automatically?
