ubuntu 2004 server on-boarded to uyuni but unable to subscribe to channel

[jawahk]

Problem description

we are able to on-board ubuntu 2004 server to uyuni successfully with saltminion but unable to subscribe to channels, need help to sort thatup

Steps to reproduce

1.on-board the server and try to subscribe the channel via uyuni it throws error

error message :
Failed to apply state: channels.

\ the\n saltenv was not explicitly set.\n\n pillarenv\n Specify a Pillar environment to be used when applying states. This\n
\ can also be set in the minion config file using the\n :conf_minion:pillarenv option. When neither the\n :conf_minion:pillarenv

Hey @jawahk
would you consider first upgrading your uyuni to the newest version?
Also make sure you're onboarding your clients the right way. Either use the WebUI, or refer to this part of the docs:
