I have several FreePBX instances running. All can run yum update, but one consistently fails with the following error:
Could not retrieve mirrorlist http://mirrorlist.sangoma.net/?release=$releasever&arch=x86_64&repo=os&dist=$dist&staging=$staging error was
14: HTTP Error 500 - Internal Server Error
The PBX is running fine otherwise. Full internet connectivity. The Sangoma-base.repo file is identical to the file on a PBX that can run yum update. The 500 error from the sangoma mirrorlist appears legitimate.
