Linux

Tell us what commands you ran exactly and what the terminal responded.

(Do this in general when asking for Linux help btw. that makes it a bit easier to give a useful reply straight away.)

As a brand new user, you don't need to use any commands to install librewolf. Open "Software Manager", type "libre" in the search bar and install the first result.

Install it from your Software Center. It's really easy and need no command at all.

I believe I’ve solved the issue thank you all for the help!

Just use the Flatpak, it makes everything much easier:

You have 3 solutions :

• RUN THESE COMMANDS

sudo apt update && sudo apt install -y wget gnupg lsb-release apt-transport-https ca-certificates

distro=$(if echo " una bookworm vanessa focal jammy bullseye vera uma " | grep -q " $(lsb_release -sc) "; then lsb_release -sc; else echo focal; fi)

wget -O- https://deb.librewolf.net/keyring.gpg | sudo gpg --dearmor -o /usr/share/keyrings/librewolf.gpg

sudo tee /etc/apt/sources.list.d/librewolf.sources << EOF > /dev/null Types: deb URIs: https://deb.librewolf.net Suites: $distro Components: main Architectures: amd64 Signed-By: /usr/share/keyrings/librewolf.gpg EOF

sudo apt update

sudo apt install librewolf -y

• USE THE DISTRO APP STORE

• USE FLATPAK (just enter this command into the terminal)

flatpak install flathub io.gitlab.librewolf-communitym

Step 1:

Go to software

Step 2: search librewolf

Step 3: install it

Sometimes the CLI is more complicated

One thing that could help is showing what is going wrong. Do just the icon does not appear? Do some error show up?

But regardless, I see that Librewolf is not packaged in Debian official software repositories (online storage a software packages are downloaded from), so they ask you to add their own repository manually, which for APT case (package manager in Linux Mint) is an overwhelming amount of code to type to say at least.

You say you are a new user, so I can highly recommend that if something is not officially available through simple apt install to try Flatpak. Official guide: https://flathub.org/setup/Debian, TLDR:

sudo apt install flatpak   # Installs flatpak to your system
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo   # Adds Flathub, the biggest store for flatpaks

Once it's there:

flatpak install librewolf

Someone using Linux for years might know where stuff on system is placed and not fear not knowing what a command do and how to undo it. But if you don't know what is happening, better to stick to distribution provided sources. Otherwise the equivalent would be like typing some commands in Windows to change registry keys :). I think Librewolf should recommend Flatpak by default instead.

Sorry if this is too much info, just tried to explain things a little more than usual.

Websites can be vague, or outdated. Is there any error from running the command?

Sudo apt install librewolf

Sudo apt install flatpak

Flatpak install librewolf

If that doesn't work then I recommend you try just installing it from your package manager of choice

But if that doesn't work then I don't know what else I can do for you mate. Firefox broke on my version of Linux mint just uninstalled it and used unchromeium Linux and it's subsequent distros can be quite weird at times
