Might’ve been going on longer than 2.6.22: [Cursor 2.5/2.6] Taking longer than expected - #4 by Andrew_Leonidov based on this article. Im going to try a 2.3 revision.
Ran into the same thinking issue on basic prompts on 2.6 as well afte rplaying for a bit.
Im almost wondering if its a problem with the service, as the version i was running before was 2.6.20 right around composer time.
not sure if somethings happening external to the downloads, but ill keep chasing versions and ghosts until i can maybe find stability 
otherwise, guess its the world telling me that proxmox doesnt need fixed today.
