Hi there @Sam_Kemp,
Thanks a lot for the message. As you can see in this error message, you happen to have ended in a rather specific situation with “conflicting” information in Rockstor’s database. As you do not have this rock-on installed, the following command may be able to help:
/opt/rockstor/bin/delete-rockon CouchPotato
This script will erase any mention of this rock-on in Rockstor’s database, thereby freeing you from the conflict you encountered (at least I believe it can help).
As to what happened and why it happened, things are a little more obscure. As @phillxnet mentioned, there may have been a timeout happening at the wrong time leading to incomplete information in Rockstor’s database related to rock-ons. By curiosity, you mentioned you do not have CouchPotato installed currently, but what is ever installed in the past, or failed when trying to do so?
I’m planning on looking into making this area of Rockstor more robust to these situations in the future, but for the time being, the script above should be able to move you forward, pending nothing bigger is happening on your machine:
Hope this helps,
