Potential upgrade issue on remote agents
Bamboo might be unable to upgrade add-ons on running remote/elastic agents:
This long standing upstream issue had been resolved as of Bamboo 5.3. However, there seems to be a regression in Bamboo versions 5.6+, which expose a similar defect.
In case you are affected, this can usually be remedied by restarting the Bamboo server or disabling/reenabling the remote agent.
Please refer to our KB article Unable to execute task due to plugin not being installed for details.
