Lost network connection with Ubuntu upgrade?

April 17, 2017

Did you upgrade your Ubuntu installation to 16.10 or 17.04 recently?

Did you have an Ethernet connection to the outside world?

Are you now not connected?

If you can answer yes to all these questions, this blog post may be for you. I have found this will fix it. This may not be the best solution however:

sudo rename /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf /usr/lib/NetworkManager/conf.d/_10-globally-managed-devices.conf_backup
sudo service network-manager restart

If you’re not bothered about keeping a copy of the file, just ‘rm’ it.

Try this command if the above does not fix it:

sudo dpkg-reconfigure resolvconf

Just a note of thanks to the authors of Qalculate! because I’ve just discovered it today. My elderly Casio fx-7700GB has started to consume batteries like Smarties. With Qalculate! I can continue to do calculations with fractions so I don’t lose precision to decimals in my Circuit Theory homework.

Installing it on Ubuntu (assuming you’re using the default window manager) makes it less pink as well.
