Why I get error Failed to execute child process "/sbin/ifconfig" when opening Nutty?

  • 772

I am in Ubuntu 18.04, I installed Nutty using command

sudo snap install nutty

while trying to open using

sudo nutty

I got this error:

[_LOG_LEVEL_WARN 03:18:10.669274] nutty.vala:1248: Error encountered in execution of sync command [/sbin/ifconfig -s]: Failed to execute child process "/sbin/ifconfig" (Permission denied)

Any ideas will be appreciated, thanks!

  1. The ifconfig command is provided by the net-tools package, which is no longer installed by default on 18.04. It is deprecated in favour of the more versatile ip command. Also see ifconfig missing after Ubuntu 18.04 install for more info.

    What you could try is to install that package anyway, as it is still available in the repositories:

    sudo apt install net-tools

    After that the missing /sbin/ifconfig command should be available, but I can't say whether it would be able to work correctly with the rest of 18.04's new networking stack and with your snap application. If it fails, remove that package again.

    As a long-term solution, you should file a bug report for the maintainer of your nutty snap package and ask them to update their software to use ip instead of ifconfig from now on.
