FreePBX Error: Trying to remove "sangoma-pbx", which is protected
You might have run into this error while attempting to do a yum based update of a Sangoma FreePBX 14 system. This can be caused by an accidentally released high level package that is no longer in the repos and needs to be backed out.
You should be able to fix this with this command:
yum downgrade kmod-forcedeth
Once you do this...
As usual and you should be all set.
