I just installed Ubuntu 18.04 and going through all my dotfile-scripts to properly configure Ubuntu automatically as much as possible. Looping through gsettings I was able to configure most settings as I want them but I haven't found anything in gsettings related to "Connectivity Checking" which is new in Ubuntu 18.04 LTS (at least not included in 16.04 LTS).

I can turn off Connectivity Checking through Settings -> Privacy but how can I do this programmatically? Just uninstall network-manager-config-connectivity-ubuntu? I was able to turn off other privacy settings through gsettings.

Viewing the file list of this package at https://packages.ubuntu.com/bionic/all/network-manager-config-connectivity-ubuntu/filelist indicates that there is just one settings file (/usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf) but it does not show any possibility to enable/disable the feature.

Any help is appreciated.

UPDATE 2022: Please note that - even though this answer was accepted - the internal conf file shouldn't be edited manually according the the comment by thaller. The mentioned solution is: Adding a config file to the /etc/NetworkManager/conf.d directory - Documentation:

you can add additional .conf files to the /etc/NetworkManager/conf.d directory. These will be read in order, with later files overriding earlier ones.

Alternatively using D-Bus: busctl --system set-property org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager ConnectivityCheckEnabled "b" 0

(Haven't tested those options myself)

Original Answer: There is a flag in the file /var/lib/NetworkManager/NetworkManager-intern.conf that is set to false if you disable the setting in the UI:


You can use the tool crudini to set the flag using the command line or a script:

sudo crudini --set /var/lib/NetworkManager/NetworkManager-intern.conf "connectivity" ".set.enabled" "false"

For some reason the ui doesn't get updated until a reboot (didn't test logoff/login). Maybe there is some other command line tool that does the change and ensures that the UI gets updated as well.

btw: I used the following command to get the files that changed recently (only checked /var and ~ so far):

sudo find /var -newermt "-1 minute" -ls

There aren't any changes to gsettings. I monitored the settings using this command:

dconf watch /
  • Thanks for the information. I verified that the same file is updated for me and it is. I haven't tried to actually add it to my dotfiles script yet.

    /var/lib/NetworkManager/NetworkManager-intern.conf is internal, it should not be modified, as the code comment there says. If you'd like to edit the setting via config-files, the it's best to put a snippet to /etc/NetworkManager/conf.d. Alternatively, use D-Bus busctl --system set-property org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager ConnectivityCheckEnabled "b" 1 which indeed will write the configuration to the internal file.

  • Thanks @thaller for the command, but you should replace 1 by 0 to disable the connectivity check

I just wanted to add that you can also disable the connectivity checking by simply creating an empty file:

sudo touch /etc/NetworkManager/conf.d/20-connectivity-ubuntu.conf

This file will override any settings found in /usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf.

    I just tried this on a new Ubuntu 18.10 installation and the connectivity option disappeared completely from the Settings -> Privacy tab. I suppose that means it is off ;)
