When deploying and the snap is not available in /tmp/slurm.snap adding a unit fails

[erik78se]

So, the slurm stack is deployed in vsphere:

Then I did:

juju add-machine --constraints "mem=32G cores=8" added machine 7 juju add-unit compute --to 7

.... then the install hook failes with the below error:

unit-compute-2: 11:08:20 ERROR unit.compute/2.juju-log Uncaught exception while in charm code:

@erik78se thanks for reporting this. I don't see this issue popping up anywhere so I'm going to close this out. Please reopen if this pops up again.
