Error installing:(unknown package)

Hi Guys
Running v17 on a rpi1 and had an update available this morning. Tried a couple of times but fails with the above error.
Logs here

You have the v18 repository installed, a clean downgrade to v17 stable is not supported.
Not sure which package thrwos that error. but If you are on a test build I suggest:

  1. Do upgrades via command line as it gives more infos
  2. Stay in the testing thread if you have problems.

Downgrading isn’t supported.

Ah yes. Forgot i added the 18 to a pi but didn’t run the update. (Waiting to fix the boot loop) then cloned it to another pi.
Clean install and working well
