Hi,
after upgrading Jira Software 8.2.2 to 8.2.4 using the Linux installer the following error appears at "Administration > Applications > Versions & Licenses":
"Jira Core must be updated to be compatible with this version of Jira Software."
The error appears although both Jira Software and Jira Core are version 8.2.4 as you can see in the screenshot.

I also tried manually upgrading Jira Core by using the Jira Core installer atlassian-jira-core-8.2.4-x64.bin but the error still shows up.
