I've been trying to install Forticlient VPN on LMDE 5 (Debian Bullseye), and it failed on dependencies for libappindicator1.

Reading another post apparently from what I understood Mint removed that library, so I proceeded to install it.

sudo apt-get install libappindicator1

OK.

Now I try to install Foticlient VPN (7.0.0.0018):

sudo dpkg -i Downloads/forticlient_vpn_7.0.0.0018_amd64.deb

Not sure where to go from here. This is a fresh install, following another post I first tried to install libindicator7 downloading the package, same for libappindicator1, which suggested to use already existing package on repositories, so I uninstalled everything and used the command line to install with apt-get. Same error.

Even though there's this error, Forticlient VPN installs and works, but leaves your libraries messed up, and:

sudo apt-get install -f

forces you to uninstall Forticlient. Any clues?

Try to partially repack the forticlient VPN and change its dependencies. Fire up a shell and navigate to the directory with the .deb, then do:

mkdir -pv forticlient && cp -v forticlient_vpn*.deb forticlient && cd forticlient # Create a nice clean workspace
ar vx forticlient_vpn*.deb && tar vxf control.tar.?z # Unpack the deb
# Now, edit the dependencies in control to use libayatana-appindicator1 instead of libappindicator1
tar c {post,pre}{inst,rm} md5sums control | xz -z > control.tar.xz && ar rcs forticlient_vpn_mod.deb debian-binary control.tar.xz data.tar.?z # Repack the deb

Then, forticlient_vpm_mod.deb is installation-ready.

  • Thanks a lot, very illustrative. If you can, for posterity, edit the last command and replace data.tar.gz for data.tar.xz. I confirm the tray icon to which the libayatana-appindicator1 refers works perfectly.

  • @chech :: done, I've rewritten the commands to make use of glob patterns and support xz archives, it also xz-compresses control now.
