[pkg-cryptsetup-devel] Bug#886398: cryptsetup doesn't correctly unmount encrypted disk

[Michael S]

Package: cryptsetup
Version: 2:1.7.3-4
Severity: important

Dear Maintainer,

cryptsetup on my system doesn't close properly encrypted disks on reboot/shutdown, reporting '(busy)' message several times until failing.

I have this problem since moved from jessie to stretch a year ago and the problem has not been fixed until now.

I know there is a ticket 792552 suggesting some patches but neigher is working for me, I have tried:
- removing /run/udev/control before do_stop() in cryptsetup.functions
- adding `dmsetup remove_all` to do_stop()

Please could you be so kind and fix the bug properly in the package existing in stable Debian release?
