Comment 9 for bug 1453738

I just registered to confirm this issue.
I just did a clean install of 15.04 and let Ubuntu use the entire drive. LVM was checked and encrypt home folder.
I did not select full disk encryption.

After setup completed, I was asked for the password of the swap partition, which just an (enter) bypassed.
After that, I am prompted for the password every time I install updates (just enter makes it go away again).
Do I need to post more info or are these details enough to reproduce the issue?
