Welcome back guys, in today's article I am going to show you how to fix the mozilla Firefox not opening error on ubuntu. in our previous article, we discussed how to install Ubuntu on Termux, and I've been getting a few complaints from some of you saying the Mozilla Firefox isn't functioning, so I decided to come up with an article that can get this fixed for you 100%
How To Fix ?
The first thing we're going to do is make sure our repositories are up to date, to do that type the command
- sudo apt update
After that we're going to uninstall the old Firefox from our Ubuntu to do that, launch your terminal and type the command
- sudo apt autoremove firefox
Now we're going to make sure out Gnupg is up to date or installed, to do that type the command
- sudo apt Install gnupg
Now we're going to add Debian repository to our ubuntu sources repo, to do that, type or copy the command
- echo "deb http://ftp.debian.org/debian stable main contrib non-free" >> /etc/apt/sources.list
now to update the newly added Debian repository we type the command sudo apt update, and now we should get an error that says "the following signatures couldn't be verified because the public key is not available" .
To fix that copy or type the commands below in your terminal
- sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv-keys 648ACFD622F3D138
- sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv-keys 0E98404D386FA1D9
- sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv-keys 605C66F00D6C9793
after that you can now update your repository again by using the command
- sudo apt update
Now we're going to install mozilla Firefox again by using the command
- sudo apt Install firefox-esr
After successfully installing Firefox you can now connect to your vnc desktop again and you should locate Firefox in the internet option in your application menu
