FreePBX yumwrapper error

 I encountered the same thing after automatic module upgrades. I had two files located in: /dev/shm/yumwrapper/ I deleted those two files and things were happy again.

I don’t mean to offend, but I don’t know your level of Linux skill. Maybe this will help:
After logging into the server’s console (command line) enter the following two commands:

cd /dev/shm/yumwrapper/

(This will “change directory” into the directory noted in the error message.)

ls  

(That’s a lowercase letter L and this command will list any files in this directory.)

If there are any files listed, you need to delete them using the rm (remove) command. You could enter:

rm *

fwconsole restart
