Summary
"Plan your upgrade" doesn't show the latest Bitbucket versions on the page. The "Upgrade to" selector is greyed out, unable to browse other Bitbucket releases.
Environment
Bitbucket Server / Datacenter 7.19
This KB may be applicable to other Bitbucket supported releases
Diagnosis
Verify if your Bitbucket application has access to the following URL
https://puds.prod.atl-paas.net/rest/v1/upgrade/info.
For the pre-upgrade planning tool to show the latest version data, your application needs to be able to access the URL. If a connection can’t be established, for example, if you’re using a restrictive firewall or proxy server settings, the tool won’t be able to fetch any updates to version data, supported platforms, or documentation.- Generate a HAR file while rendering the "Plan your upgrade" page. The API <BITBUCKET_BASE_URL>/rest/troubleshooting/latest/pre-upgrade/info couldn't retrieve release information and marks the attribute 'stale' to true in the API response.
Cause
The API response data is marked stale because the versions are fetched from the cached version list that is packaged with ATST (Atlassian Support Tools plugin). A possible block of all outbound connectivity from the instance could be the reason for causing the issue.
Solution
Review the outbound proxy configuration and allow the connectivity to https://puds.prod.atl-paas.net/rest/v1/upgrade/info
