Hi All,

Just installed new firmware (mPower™ Edge Intelligence 5.1.5) on a MTCDT-247A (AEP AUS)

and tried the installer script (which ran fine on the previous 1.4.17 firmware I had on it) and get the following error

installer.sh: line 733: /var/config/lora/global\_conf\_src: Permission denied  
FATAL ERROR: could not obtain gateway id, Lora card not found

even though the card shows up within the Multitech GUI no worries

any ideas?

regards  
Paul

So, is there such file `global_conf_src` in that folder `/var/config/lora/`? If yes, what are its file permissions? Something like `ls -l /var/config/lora/global_conf_src` should tell.

(If further debugging is needed then please link to the installer script as well?)

Could you run the install script using sudo?

> sudo bash ./installer.sh

Yep, you must running the installer after updating again with the sudo command.  
Then everything will go well.  
Just done last evening
