password request for cryptswap1 during boot when encrypted home directory selected

Hi Craig,

Could you please attach the /etc/crypttab from the affected system?

Thanks. crypttab clearly shows that this has been set up correctly, with /dev/urandom as the key, so we should not be getting a passphrase prompt.

Please also show the output of:

  systemctl --all | grep cryptsetup

<email address hidden> loaded activating start start Cryptography Setup for cryptswap1
  system-systemd\x2dcryptsetup.slice loaded active active system-systemd\x2dcryptsetup.slice
  cryptsetup-pre.target loaded inactive dead Encrypted Volumes (Pre)
  cryptsetup.target loaded inactive dead Encrypted Volumes

I see this message when working on the command-line, i.e. installing packages via apt.

I performed a clean install of 15.04 and I am prompted for a cryptswap1 password as well.

I belive this issue may become more visible as more people upgrade.

Same. Performed a clean install of 15.04 and I am prompted for a cryptswap1 password. Get it together guys

This is reproducible in a VM by configuring /etc/crypttab to include a /dev/urandom crypted swap line. This appears to be a bug in systemd rather than in cryptsetup.

I can confirm I have the same issue after the upgrade from Ubuntu GNOME 14.04.2 LTS to Ubuntu GNOME 15.04. Anyone knows a workaround for this? Do you need any logs or conf files to confirm/resolve it? I can provide if needed.

I can also confirm that this problem exists. Looking forward to the fix.

I have just installed Wily desktop with encrypted LVM and encrypted /home and I get this error to: System asking for passphrase for cryptswap1.

It also showed several times while installing packages in Synaptic.

Having a 20 character password for unlocking my LVM I got lazy and tried to hit the Enter key without typing my password and the system continued to load Ubuntu up to the login-screen.

To me it seems like a major problem that one can enter an empty password to bypass security.

The security is not all that compromised on an LVM system but it is on a system with encryptet /home only.

Anyone find a solution yet?

Just did a clean install of 15.10 with encrypted /home and can confirm I have the problem, too.

Note: I am not using LVM.

I had this error on 16.04 LTS as well. I had it on 2 systems, so this does not seem to be fixed yet.

there are also some duplicates about this bug i think;
https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/953875
which in turn has a lot of duplicates it seems.

+1 to the list of folks who say this bug is still active. It's quite annoying in 16.04 LTS, I get this message almost every time I use some "sudo <something>" command.

It's still present in 16.10

I just bought a Dell XPS 13 and am having the same issue.
