The build failed on jammy because of a new shellcheck warning, which was
fixed in Debian already. See https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=1002270.

I have uploaded a merge to a PPA, where it built just fine. I am
attaching the debdiff for that.

Title:
  [20.10 FEAT] Increase the crashkernel setting if the root volume is
  luks2-encrypted

Bug description:
  Description:
  In case the volume containing the root filesystem is encrypted using LUKS2 
the memory used while unlocking the volume may exceed the size allocated to the 
kdump kernel. This will lead to a failure while processing kdump and the dump 
file will not be stored. Unfortunately, this condition may not be detected by a 
client before a problem occurs.
  The request is to have the kdump package installation script check for LUKS2 
encryption (more precisely for Argon2i PBKDF, which is the root cause of the 
high memory usage). If the condition is met, the installation procedure should 
increase the crashkernel parameter to a higher value (>=512M)or issue a 
warning, if the system memory is insufficient to reserve enough crashkernel 
memory.

  Business Case:
  Pervasive Encryption and Secure Execution require encryption of the 
filesystems in order to keep customer data secure at all times. With the 
increasing usage of these technologies, the number of kdump will rise too, 
typically at inconvenient times, when the kdump is triggered due to a real 
customer issue.
  With the suggested change, the number of customer complaints and effort to 
handle them will be reduced.
