Comment 5 for bug 1597154

I have installed a fresh 16.04.
I have these partitions

Device Start End Sectors Size Type
/dev/nvme0n1p1 6 76805 76800 300M EFI System
/dev/nvme0n1p2 76806 19691128 19614323 74,8G Apple Core storage
/dev/nvme0n1p3 19691129 19849820 158692 619,9M Apple boot
/dev/nvme0n1p4 19849984 20850687 1000704 3,8G Linux swap
/dev/nvme0n1p5 20850688 61279231 40428544 154,2G Linux filesystem

During the install/update process, I add to enter the password for the swap partition about 10 times.
After this tedious process, the system is still asking for the password for the swap at each boot. I have patched ecryptfs-setup-swap as mentioned above but I still have to enter the password at each boot. Should I relaunch/update something having patched ecryptfs-setup-swap?? Should I try to change the swap GPT partition type??
