Symptoms

While upgrading or installing Bitbucket Server, users cannot get past the "enter license" screen although they have a valid license.

Cause

This issue is likely caused by multiple Atlassian applications (or other Java web applications) being located at the same hostname and context path and overwriting each others JSESSIONID (changed to BitbucketServerid in BitbucketServer 5.x onwards) cookies.

For example, if you have JIRA located at:

https://my-domain:8080

and Bitbucket Server located at:

https://my-domain:7990

Then accessing a page from JIRA will invalidate your Bitbucket Server session.

Resolution

To confirm whether this is the case, try clearing the cookies from your browser and using Bitbucket Server. You should experience no problems until you log into JIRA again.
