cross-checking

Question

After upgrading From SCOM 1807 to 2019 and UR3 we are not able to upgrade our Linux agents.
When we try to upgrade ore Oracle Linux agetns from console, the console hangs forever. To use the console again i must end the process at the background.

Current agent version is: 1.6.0-163
Oracle Linux Version is 7.3 and 7.9

Another strange problem is that I can only upgrade the Version 7.9 (starting the upgrade process) of Oracle Linux, but even here the upgrade screen hangs at cross-checking.

**On the Operationsmanager log files i see event id: **4503****
A module reported an error 0x80FF0004 from a callback which was running as part of rule "Microsoft.Linux.Universal.Process.Ssh.Monitor" running for instance "Linux Distribution" with id:"{3E583238-0CBD-C52E-EF77-6AE80F2AF9CB}" ...

Hi @Anakonda420 ,

You could have a look what Kevin stated in his blog post for SCOM 2019 UR3 under the Update UNIX/Linux MPs and Agents section:

If you have any issues, make sure your SUDOERS file has the correct information pertaining to agent upgrade:

The problem is solved by flushing the MS health service, very strange situation.
