I have 4 servers, and I've successfully set the Channel on 2 of them to Continuous Update. On the other 2 - identical VMs running identical software when built a couple of weeks ago - it fails when I try to do this. As soon as i click on "Set", I jump back to the previous screen, and it has a large red horizontal bar telling me, "Can not set channel! Wrong status." The only thing I see different is that on the 2 that fail, "Status:" is set to "Checking for new packages" while on the 2 that succeeded, it is set to, "Server is up to date".

Steps to reproduce:

1. On Compute main screen, click on "Servers" in the left column.

2. Click on the server.

3. Click on Update on bottom right of screen.

4. Click on "Channels' (currently set to "centos_7.7 (Current Release)", so select "centos7.x (Continuous Update)"

5. Click on "Set'

Red bar of sadness will appear.

On the server in question, I've run:

yum check-update - Nothing available

yum upgrade - Nothing available rhn_check - Nothing new

I've checked for a running/stuck yum command, or rpm command, and neither appears to be running, causing the package update to freeze.

How can I get past this issue? Has anyone else had this issue?
