Swap passord is being asked multiple times while updating packages

[Saverio Miroddi]

I have a system with a crypted swap partition.

When I upgrade my packages, for no apparent reason, I'm being asked the swap password multiple times:

Processing triggers for man-db (2.7.0.2-5) ...
Processing triggers for ureadahead (0.100.0-19) ...
ureadahead will be reprofiled on next reboot
Processing triggers for systemd (219-7ubuntu3) ...
Setting up udev (219-7ubuntu6) ...
Please enter passphrase for disk MYDISK (cryptswap1) on none! ************************

Note that in the report, the partition may not be visible, because I've just removed it.
