snap remove not working after snap try

[Ondrej Kubik]

snap remove fails after use of "snap try" and removing used directory(prime) later in the process.

snap version
snap 2.37.4
snapd 2.37.4
series 16
ubuntu 18.04
kernel 4.15.0-36-generic

command:
$ snap remove opengrok
2019-03-13T12:42:13Z ERROR cannot discard snap namespace "opengrok", will retry in 3 mins: cannot discard preserved namespace of snap "opengrok": cannot unlink opengrok.mnt: Device or resource busy

snap-discard-ns output:

Hi Ondrej, I cannot reproduce (snap version 2.41+git1457.73f3b15~ubuntu16.04.1, edge channel): I've "mysnap" snap directory, then:
1. sudo snap try mysnap
2. rm -rf mysnap
3. sudo snap remove mysnap

(works, snap gets uninstalled).

Is that the scenario? Can you retest with current snapd?

Unfortunately I can't test this, as I had to recover system from broken
state to continue with my daily development. So I can only update if I get
system to this state again
