Example of setting up Session-Privacy-Messenger app in very secure, isolated way, running behind tor and ability to run multiple session accounts at once on Linux with dexsetup:

• everything downloaded and configured by below example is very standard system packages installation/configuration or pure user-space-files thing in very isolated environment by firejail and tor by proxychains.

Installation

• detect if tor is already configured, detect if to use sudo or su and install base packages.
• download dexsetup.installer anonymously by tor and run it with pre-configured arguments to install/update session and setup profile name default.

# set base packages for anonymity from very beginning because we do not want even to gitbub to spy on us.
pkgs="proxychains4 tor torsocks wget";

# detect if tor is configured for user or not
groups | grep debian-tor > /dev/null && cfg_user_tor="echo 'Tor for ${USER} is already configured'" || cfg_user_tor="usermod -a -G debian-tor ${USER}";

# detect if to use sudo or su
sudo -v; (test $? != 0) && su_cmd="echo 'Please enter ROOT password'; su - -c" || su_cmd="echo 'Please enter ${USER} sudo password'; sudo sh -c";

# do necessary system update and install all needed packages
eval "${su_cmd} \"apt -y update; apt -y full-upgrade; apt -y install ${pkgs}; ${cfg_user_tor}; exit\""

#download installer and verify file checksum
branch="main" && mkdir -p ~/dexsetup && cd ~/dexsetup && rm -f installer.sh && rm -f installer.sha512 && proxychains4 wget "https://github.com/nnmfnwl/dexinstaller/raw/refs/heads/${branch}/installer.sh" && proxychains4 wget "https://github.com/nnmfnwl/dexinstaller/raw/refs/heads/${branch}/installer.sha512" && sha512sum installer.sh | grep `cat installer.sha512` && (echo "installer fingerprint verification success") || (sha512sum installer.sh; echo "installer fingerprint verification failed"; rm -f installer.sh)

# run installer with pre-configured arguments to use dexsetup.framework just to download/update session and make profile named default.
cd ~/dexsetup && bash installer.sh DEFAULT-N c-y dexsetup-update-y session-y session-profile-y session-update-y

Setting up multiple profiles

• with dexsetup.framework you can setup any number of profiles just in second!
• example how to setup profile named johnsmith

cd ~/dexsetup/dexsetup && ./setup.session.profile.sh johnsmith

Restore Session profile from old account

• If you been using Session app before the old profile files could be found at ~/.config/Session/
• You can very easy restore your session profile to be used secudrely by dexsetup as:

cp -r ~/.config/Session/* ~/dexsetup/session/latest/data/profile/johnsmith/

Make link and put it on Desktop

• To make a link for specific session profile on Desktop, click with right mouse button and choose make a link and move file on your Desktop or use command:

ln -s ~/dexsetup/session/latest/firejail.session.default.sh ~/Desktop/session.default.sh
ln -s ~/dexsetup/session/latest/firejail.session.johnsmith.sh ~/Desktop/session.johnsmith.sh

How to start specific Session profile

• To start session profile just double click on profile at ~/dexsetup/session/latest and choose run or run in terminal or use command like:

cd ~/dexsetup/session/latest/ && ./firejail.session.default.sh

Session directory struture

• session profile files could be found at ~/dexsetup/session/latest/data/profile/<profilename>

cd ~/dexsetup && tree -d -L 4 session
