Public bug reported: I have noticed that since upgrade to 20.04.1 (from 18.04), a warning message appears during boot: "cryptsetup: WARNING: Option 'size' missing in crypttab for plain dm-crypt mapping cryptswap1. Please read /usr/share/doc/cryptsetup-initramfs/README.initramfs.gz and add the correct 'size' option to your crypttab(5).".
AFAICT, there is no problem however. I use ecryptfs to encrypt my home directory but I don't think it's related (since the message is related to swap). This message used to appear during updates under 18.04 but I never paid attention to it. I probably use the same setup since 16.04. Others have reported the problem (https://askubuntu.com/questions/1109463, https://medium.com/@anirudha /fixing-cryptsetup-wating-for-encrypted-source-device-swapfile-error-on- linux-boot-ubuntu-20-04-5483e0dcf9e9). From what I read: - The answers indicate to edit /etc/crypttab and add a value for size but I don't know what value to use. - It seems that before 20.04, just editing /etc/crypttab was enough but some users say that they need to manually regenerate the initramfs image after each update which is boring. I have asked the question at https://answers.launchpad.net/ubuntu/+question/693615 and @bernard010 suggested to open a bug report. I have found anything worth in dmesg though. As I said everything seems fine (boot proceed normally, I can use the computer) but I expect that there is a way to permanently make this warning disappear.
