Upgraded to 2.1.0, cannot deploy

I noticed that I also need to deploy to a "Target type" of "Thing group". If I try and deploy to "Core device", the deploy fails with a similar error message as above. So I'm wondering if the deploy actually worked for a "Thing group"? It stays "Active" even if I revert to Cli version 2.0.5.

I think the deploy is failing even when I deploy to a "Thing group".

I notice on the "AWS IoT > GreenGrass > Core Devices > LeeThing2" page the Greengrass Core software version is 2.0.5, where it needs to be 2.1.0? I deleted and recreated the thing (after verifying that the Greengrass.jar version I was using was 2.1.0) and it still shows 2.0.5. I tried just deploying ggOpcLee (my lambda) with no other components, to LeeThing2, and got:

So I put back components Cli / LambdaManager / LogManager / Nucleus (all 2.1.0 versions) and got:

I notice "aws.greengrass.Cli={thing/LeeThing2==2.1.0, thinggroup/GreengrassQuickStartGroup2==2.0.5}," here, and I'm not sure where GreengrassQuickStartGroup2 is coming from (it's not listed on my "Groups" page), nor why it's asking for version 2.0.5 for Cli. Also it looks like Cli 2.1.0 is requiring Nucleus < 2.1.0 ("aws.greengrass.Nucleus={aws.greengrass.Cli=>=2.0.5 <2.1.0")

Any further thoughts appreciated...

I uninstalled 2.1.0 and reinstalled it, and now the deploy works! Apparently my 2.1.0 installation got scrambled when I upgraded from 2.0.0.
