We linked to the same discussion on askubuntu.com (I replied you there).
My hope when reporting this is that we don't have to do the workaround
you described after each kernel update.
Did you open another bug report ? In this case, I will mark this one as
a duplicate.
** Description changed:
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
+ As I said everything seems fine (boot proceeds normally, I can use the
computer) but I expect that there is a way to permanently make this
warning disappear.
