Error updating Calamari on multiple Linux tentacles

Octopus Server 3.3

When updating Calamari on multiple Linux tentacles, I get:
The process cannot access the file ‘C:\Program Files\Octopus Deploy\Octopus\Calamari.3.3.0.tar.gz’ because it is being used by another process.

on all except 1 of them. Retrying after the 1 updates does the same for the remaining. It looks like the updater is locking the file against itself.

Hi Ryan,

Thanks for reporting this issue. The fix will be in the next release. You can track it here:
