Hi MMnbJEE,

Thanks for your bug report. I can't see anything in it though that would
suggest libblockdev-swap2 is involved in your problem at all. The bug
report is also way to vague to tell what your problem is or where to
assign it. (Honestly it also seems more like a support request than
a bug report and the bug tracking system is not a support forum.)

Regards,
Andreas Henriksson
