On Ubuntu 16.04 the network-manager-openconnect and
network-manager-openconnect-gnome plugins are not usable because they
are to old to use with the current version of network-manager.
This is the english version of this guide from a german ubuntu support
forum.
Unofficial built packages are available here:
http://tomtomtom.org/networkmanager-openconnect_1.1.93-1_i386.deb
http://tomtomtom.org/networkmanager-openconnect_1.1.93-1_amd64.deb
NOTE: You won´t get any security updates for this! It is just a
workaround until the packages will have been fixed in the official
repository!
Using VPN is a security feature - so it is better to build the package
manually from source because you don´t know what I put into the
packages. :-P
At first remove the unusable packages
sudo apt-get purge network-manager-openconnect network-manager-openconnect-gnome
You will need the build-dependencies.
sudo apt-get build-dep network-manager-openconnect
(NOTE: For this the 'deb-src'-Sources in /etc/apt/sources.list must be
active.)
You can do this with sed e.g.
sudo sed -i s/#deb-src/deb-src/g /etc/apt/sources.list
the new dependency for the new version.
sudo apt-get install libnm-dev
and the sourcecode from GNOME project.
wget http://ftp.gnome.org/pub/GNOME/sources/NetworkManager-openconnect/1.1/NetworkManager-openconnect-1.1.93.tar.xz
Unpack the tarball
tar -xf NetworkManager-openconnect-1.1.93.tar.xz
change to the unpacked directory
cd NetworkManager-openconnect-1.1.93
and run the configure script.
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
--libexecdir=/usr/lib/NetworkManager/
--enable-more-warnings=yes --disable-static
start compiling .
make
and install manually
sudo make install
install the dependency for use the software
sudo apt-get install openconnect
or build a package with checkinstall
sudo checkinstall
If you do so enter this:
networkmanager-openconnect
as package name
adduser, libc6, libdbus-glib-1-2, libglib2.0-0, libnm-glib-vpn1,
libnm-util2, network-manager, openconnect
as requirements
and
network-manager-openconnect, network-manager-openconnect-gnome
as conflicts.
If you get errormessages by installing the package try
sudo apt-get -f install
to resolve unmet dependencies.
To use the software it is necessary to add a systemuser for this
sudo adduser --system --quiet --home /var/lib/NetworkManager
--no-create-home
--gecos "NetworkManager OpenConnect plugin"
--group nm-openconnect}
At last restart the system.
network-manager-openconnect
and notnetwork-manager-openconnect-gnome
because they're not running GNOME, no: you need the-gnome
package, because it provides the actual/usr/lib/x86_64-linux-gnu/NetworkManager/libnm-vpn-plugin-openconnect.so
file referred to by the files installed bynetwork-manager-openconnect
:(
