Disclaimer: This gist is a bit outdated now. The client download page now redirects to a login page that the downloads are guarded behind. You'll want to do a web search for a pulse secure deb file and install that now. Try: http://webdev.web3.technion.ac.il/docs/cis/public/ssl-vpn/ps-pulse-ubuntu-debian.deb. When I installed Pulse Secure 9.1R13, I didn't need to do anything else to get it working.

To install Pulse Secure for Ubuntu 20.04, it is a bit complicated since the support isn't great.

First, we'll want to go through the form at https://www.pulsesecure.net/trynow/client-download/. You'll get an email with download links to the latest versions of pulse secure. Download the Linux one with the deb file and then you can install it using dpkg from your downloads folder.

$ cd ~/Downloads
$ sudo dpkg -i ps-pulse-linux-[your-pulse-version]-ubuntu-debian-64-bit-installer.deb

Now, we'll want to go into the pulse directory and install the dependencies. We update the shell script file first to recognize Ubuntu 20.

$ cd /usr/local/pulse/
$ sudo sed -i "s/UBUNTU_VER\ \=\ 18\ \]/& \|\|\ [\ \$UBUNTU_VER\ \=\ 20 \]/" PulseClient_x86_64.sh
$ ./PulseClient_x86_64.sh install_dependency_packages
$ sudo apt-get install libenchant1c2a

Next, we'll want to create an extras and debs folder inside the pulse folder.

$ sudo mkdir /usr/local/pulse/extra
$ sudo mkdir /usr/local/pulse/debs   

Then we'll want to download the following debs into /usr/local/pulse/debs/.

$ cd /usr/local/pulse/debs
$ sudo wget http://archive.ubuntu.com/ubuntu/pool/main/i/icu/libicu60_60.2-3ubuntu3_amd64.deb
$ sudo wget http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb
$ sudo wget http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb

Next we will extract the debs into the extras folder.

$ cd /usr/local/pulse/extra
$ sudo dpkg -x /usr/local/pulse/debs/libicu60_60.2-3ubuntu3_amd64.deb .
$ sudo dpkg -x /usr/local/pulse/debs/libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb .
$ sudo dpkg -x /usr/local/pulse/debs/libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb .

Then we'll want to add the library path to our shell startup file and for convience, the pulse secure command can be aliased as well. Likely .bashrc if you're using bash or .zshrc if zsh.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pulse/extra/usr/lib/x86_64-linux-gnu/
alias vpn=/usr/local/pulse/pulseUi

By default, pulse secure will have its output go directly to the terminal from which you ran it from. If you'd like to keep those separate and detach the program from the terminal when you run it, you can instead create the following alias: alias vpn="nohup /usr/local/pulse/pulseUi >| ~/.pulse_secure/pulse/pulse-output.log &" (thanks @GreyCardinal!)

Lastly, we want to make sure to source that same shell startup file e.g. source ~/.bashrc so the changes are loaded. We can then startup the client.

$ vpn

If you get disconnected and the GUI is stuck in a "reconnecting" status, you can use pulsesvc -K to kill the process.

@da0ist I haven't used Ubuntu in a while so it may be different. But if your version of pulse secure is 9.1r11, there were some significant changes. The maintainer of the arch linux user package for pulse secure (see discussion here https://aur.archlinux.org/packages/pulse-secure/) wasn't able to get the host checker working on that version. I've still been using version 9.1r9

It works for me on Ubuntu 20.04.2 LTS.
Thanks for your helpful guideline.

@eugenetriguba why did you choose to extract packages under /usr/local/pulse/extra and workaround it with LD_LIBRARY_PATH, instead of simply installing those into a system, as usual (i.e. sudo dpkg -i libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb libicu60_60.2-3ubuntu3_amd64.deb libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb).
Tried installing on my system, and everything works flawlessly so far.

@Youw Under the resources section, you'll find this post: https://askubuntu.com/a/1142879

There's another answer in that post that uses your approach: https://askubuntu.com/a/1222612

Either one works fine. I have no strong preference. This gist is just a combination of stuff already out there on the web to put it in one place so I could refer back to it.

Youw commented May 20, 2021

Sounds reasonable. My preference on the second approach is that it is simply less steps to achieve (practically) same result.
I asked only because I assumed there could be issues with having those packages installed, which I didn't know or didn't face yet.
I guess it makes it "no known issues so far". Thanks.

@Youw Agreed. I think simpler is generally better. I'll look into it, try it out, and consider updating the gist if I don't come across any issues. Thanks for bringing it up!

I sent form from https://www.pulsesecure.net/trynow/client-download/ - but have not recived any email... Maybe this is because Pulse Secure is Ivanti now ;/

@miedzikd You can find downloads for it hosted on other sites if needed by doing a web search. For example: http://webdev.web3.technion.ac.il/docs/cis/public/ssl-vpn/ps-pulse-ubuntu-debian.deb

I faced the [: =: unary operator expected error on my Pop!_OS 20.04 and thanks to the link @eugenetriguba posted above https://community.pulsesecure.net/t5/Pulse-Desktop-Clients/Unable-to-install-on-Ubuntu-18-04-PopOS/m-p/41077/highlight/true#M1087 I was able to make it finally work.
Keep in mind you need to replace OSNAME=$(lsb_release -d | grep -o "Ubuntu") to OSNAME=$(lsb_release -d | grep -o "Ubuntu\|Pop")
in both tmp/DEBIAN/postinst and /usr/local/pulse/PulseClient_x86_64.sh files

@eugenetriguba I downloaded pulse secure deb file from your google drive and installed it. But when I type cd /usr/local/pulse/ in the terminal, I'm getting following error. Please help me to sort this out.
bash: cd: /usr/local/pulse/: No such file or directory

@gihandilanka-github They put their files in /opt/pulsesecure. With newer versions, you'll want to make sure you also have their pulsesecure systemd service running as well.

There is an article with version 22.2.R1 of PulseUI
(https://www.cyberithub.com/how-to-install-pulse-secure-vpn-client-on-ubuntu-20-04-lts/

Link to the deb package from article:
https://dl.technion.ac.il/docs/cis/public/ssl-vpn/ps-pulse-ubuntu-debian.deb

I've tried it and it work for me.

Have you considered to use NetworkManager+Openconnect plugin ?
It works fine for me, no need for 3PP SW.

Tried console client today. Works with additional parameter --protocol=pulse
Will try with networkmanager tomorrow
