How do i recover from a failed upgrade of UPM

Hi,

I was upgrading the Plugin manager withing Confluence and the server crashed.

Now i get

Error occurred during template rendering: Invocation of method 'getCssResources' in class com.sun.proxy.$Proxy66 threw exception java.lang.AbstractMethodError at /decorators/includes/header.vm[line 35, column 26]. Contact your administrator for assistance.

I have tried:

* index rebuild

* Disabling decorators in the db

Been unable to find much help on the error.

Any suggestions?

I fixed this last night doing the following:

1) take the ZIP backups to a safe location

2) Dump the database and back that up

3) uninstall confluence

4) remove /var/atlassian/application-data/confluence

5) drop the DB

6) Re-create the DB

7) Install Confluence from scratch

8) Copy the latest zip into /var/atlassian/application-data/confluence/restore/

9) At the end of the install chose "Restore from backup"

10) restore and re-apply add-on's and themes etc.

Not ideal but all my content seems to be there so i'm happy.

Please follow the procedure below to rollback the plugin to a previous version:

1) Shut down Confluence;

2) Remove the existing UPM JAR file from this directory in your Confluence home directory:plugins/installed-plugins (The name of the JAR file may be prepended with a number, such as: 846688264762062110.atlassian-universal-plugin-manager-plugin-2.x.x.jar);

3) Copy an older version of UPM plugin .jar file into the same directory (https://marketplace.atlassian.com/plugins/com.atlassian.upm.atlassian-universal-plugin-manager-plugin/versions).

4) Start Confluence.

Hope it helps!

Cheers

Could you delete the newly installed version of the UPM using https://confluence.atlassian.com/display/CONFKB/How+to+manually+remove+malfunctioning+add-ons

That should give you back the old bundled version.

Very old, but ran into this today doing upgrades.

The atlassian comment was correct. Find the upm jar for the version you are running. Remove any upm jars from the plugin directory. Put the correct jar in place, and start. Should work.

Another thing that will work that is preferable to complete reinstall is move the plugin directory to plugin.old. Recreate directory with the proper permissions. The plugin you need may actually be downloaded automatically on start. Other wise you can put the correct jar into place.

This issue stems from the wrong jar being loaded for the version of the atlassian in use. Correct the version will resolve it.

Have any of these suggested solutions been successful? I'm will to wipe the Confluence instance, install the new version (I need to upgrade anyway), restore from backup, and purchase the few 3rd party plugins I have installed. Anyone care to stop me before I leap this cliff?

Still broken.

From what I can decypher (I'm not a java coder but have done some debugging in my time) it is almost theme related.
