I installed Octopus Server 1.6.0.1714 and ran “Upgrade all” from the Environments page to upgrade my tentacles. Several of my tentacles upgraded successfully, but several of them did not. I reran the proces with no success.
I then ran the installer program on the servers in my environments that had failures. After the install/upgrade completed, I received the following error:
Could not start Octopus tools: Could not load file or assembly ‘System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes’ or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
I tried uninstalling my tentacle and reinstalling. I also tried restarting. I don’t see anything in the event log. No luck. Any ideas?
