Comment 22 for bug 1458322

Have updated the patch to work with 18.04, here are the instructions I just used to build it (personally I builds like this in a VM)... ultimately you get the file 'network-manager-gnome_1.8.10-2ubuntu1_amd64.deb' and that is the only thing you need to install on normal 18.04 system where you want the fix...

sudo sed -i 's/^# \(deb-src \)/\1/' /etc/apt/sources.list
sudo apt-get update
sudo apt-get build-dep network-manager-applet
wget http://archive.ubuntu.com/ubuntu/pool/main/n/network-manager-applet/network-manager-applet_{1.8.10.orig,1.8.10-2ubuntu1.debian}.tar.xz
tar xf network-manager-applet_*.orig.tar.xz
cd network-manager-applet-*/
tar xf ../network-manager-applet_*.debian.tar.xz
wget -P debian/patches http://gist.github.com/Lantizia/2f32f0ca8193a61ceefb0c8c95e92bcc/raw/hide_unmanaged_interfaces.patch
sed -i '1s/^/hide_unmanaged_interfaces.patch\n/' debian/patches/series
sudo dpkg-buildpackage -b
# Ignore the bit about not being able to sign it
# Only need to install 'network-manager-gnome_1.8.10-2ubuntu1_amd64.deb'
