Upgrading CUC from 7.1.5.33900 to 7.1.5.35901

[fbaheux.ext1]

Hello,

I'm trying to upgrade a CUC from 7.1.5.33900 to 7.1.5.35901.

The installation went well, but I'm unable to switch version, from browser or from CLI.

When I entered utils switch-version, I got several ERRORS:

 - first: ERROR: Acquiring Lock failed. I did a utils system restart

- then: ERROR: Sync after switch version failed.

I did multiple restart, and I always have the Sync after switch version failed.

Do you have any idea?

Can you try reinstalling the upgrade file after restarting server and then do a switch version. If the issue persists then you need to gather the install logs to troubleshoot further.

I try to reinstall the upgrade file and to do a switch version again.

I'm still having ERROR: Sync after switch version failed

How can I acces the install logs?

You can collect them via RTMT > Trace and Log Central

I collected the Install Logs from my Unity.

As I do not know which one could be interesting, I zipped them all.

I really don't know what is happening.

We decided to do a fresh reinstall.
