Ok here's the solution...  I've followed these instructions: https://askubuntu.com/questions/1135065/cant-run-pulse-secure-on-ubuntu-19-04-because-libwebkitgtk-1-0-so-0-is-missing with only difference here:  So instead version 19:  sed -i "s/UBUNTU_VER\ \=\ 18\ \]/& \|\|\ [\ \$UBUNTU_VER\ \=\ 19 \]/" PulseClient_x86_64.sh replace this line with your current version, in my case:  sed -i "s/UBUNTU_VER\ \=\ 18\ \]/& \|\|\ [\ \$UBUNTU_VER\ \=\ 20 \]/" PulseClient_x86_64.sh Then, do the rest and after that install this package: https://ubuntu.pkgs.org/18.04/ubuntu-main-amd64/libenchant1c2a_1.6.0-11.1_amd64.deb.html  sudo apt-get install libenchant1c2a You should be able to run Pulse UI now by running this command:  /usr/local/pulse/pulseUi It worked for me. Good luck! :)    ... View more
