I tried to recreate the i2p+ install from
https://stormycloud.org/install-i2pplus/
While this install can be recreated in all Linuxes I selected my target Debian-12.
I created an INDEPENDENT VM based on Debian 12 template. My Debian-12 template does not have firefox-esr, nautilus, games etc so I proceeded with the following.
sudo apt install default-jdk thunar firefox-esr -y
sudo adduser i2p && sudo usermod -aG sudo i2p
Because I do have a copy of i2p+ in Downloads:
sudo cp /home/user/Downloads/i2p+ /home/i2p/i2p+
su i2p
cd /home/i2p
java -jar i2p+
Bottom line: default-jdk and thunar work when I call them from i2p user terminal but firefox-esr can’t load the profile and exits. I think that firefox-esr should be able to start. Shouldn’t it?
