[Error/13] Upgrade failed: Failed to find a release matching the specified version: Mainline/2.6.4.2 - This version may no longer be available to download, you should update to a newer version.

Steps to reproduce:

  • Step 1: Update AMP on Windows per cmd with ampinstmgr upgrade ADS

Actions taken to resolve so far: I tried to get some help from Chatgpt, didnt work too. Then i tried to reboot my sytem, didnt work too. Also downloading and installing the update with the AMP Instance Manger with gui didnt work.

You’ve got networking issues that are preventing the download of update data. Check your systems internet connection and try again.
