Yes everyone is having the same issue on the AMP program with Minecraft Bedrock Server for Linux. It has been brought to the attention of several people in this community and businesses offering AMP Linux hosting for Minecraft Bedrock Servers.
This is already fixed in the development release. You can try it early if your license supports it. sudo su -l amp and ampinstmgr switch (nstancename) development and change (instancename) to your actual one, should do the trick to let you upgrade again. Windows only needs the second command. Then update inside the instance again.
