Cannot install mySQL, PHP, Python on ReadyNAS 212 ver. 6.10.8

[Bva22]

I am trying to install mySQL, PHP and Python on a ReadyNAS212 but it always fails. I could install istat, Kernel plus and Plex Media server.

Any solution ?

I finally found a solution : download the debian package and then manual install within ssh session with  'apt-get install'. I could interact during the installation process and force the installation of non authentificated package.

Hello @Bva22 
  
And welcome to the NETGEAR Community! 🙂 

I wondered if is there any other issues or glitches you are facing in your ReadyNAS while performing disk tests, or in any another funtionalities.

If yes, then let me know them briefly.

Error

To overcome this error occured insert --allow-unauthenticated while trying to installating the services.

I encourage you to mark the appropriate reply as the “Accepted
