After JIRA upgrade to 8.3.2 from 7.7.0, we cannot install JIra Service desk plugin

[Sudharsan Gopalakrishnan]

Hi.

We recently upgraded JIRA software from 7.7.0 to 8.3.2. After that we tried to update JIRA service desk plugin and also tried to uninstall & install back. It shows "An unexpected error occured , refer logs for information"

Please help me how to resolve this issue

I ran into similar issue. But mine was due to wrongly disabling the system add-on.

You can either follow the steps on the article to fix it. This didn't really work for me.

All do these kinda stuff on staging

All I did was to enable the plugins through database. 

Check the plugins that are disabled

SELECT * FROM pluginstate where pluginenabled = 'false';

Make sure to stop jira before running the below command

Enable all the plugins that are disabled

update pluginstate set pluginenabled = 'true' where pluginenabled = 'false';
