Problem with pkg command

Morning, I’m starting to admit I’m not an expert of TrueNAS, but I’m experiencing a problem on pkg command thai I used several time in TrueNAS with success. I would like to create in a jail a paperless-ngix distance starting from command line. I failed at first pkg update command. This is still true if I tried to update existing jails to latest version. The message is “Please check your network”.
Any suggestions please?

Hi, are you talking about Core’s jail?

I’m sure there’s more to the message–can you give the exact, complete message you’re seeing?

And presuming you’re using CORE, which version?
