apt-offline VS manjarno

If you have a USB stick and access to a Windows computer (neighbours, friends, etc.) with Internet access, you can use https://github.com/rickysarraf/apt-offline for this.

Take a look at https://github.com/rickysarraf/apt-offline

One possibility would be http://rickysarraf.github.io/apt-offline/. With this tool you can copy the necessary packages, including their dependencies, to a USB stick and then install them on a computer without internet access.

There was apt-offline that did a very good job as far as that goes.

Check out apt-offline which is packaged for Ubuntu.

I have also seen apt-offline.

Here's the discussion about the "ERROR: Path for keyring invalid" problem with apt-offline: https://github.com/rickysarraf/apt-offline/issues/102

If you cannot establish another network connection, you could solve the problem by using https://github.com/rickysarraf/apt-offline. You will need a Debian based distribution with internet access (a live distribution should probably work) and an USB Stick. This will copy the required package including dependencies to a USB stick. With this you can install the package on the computer without internet connection.

Manjaro is just broken. For more info see Manjarno.

Why you shouldn't use Manjaro. If you want an Arch based distro, go EndeavourOS, as it Arch with an installer.

I would replace Manjaro for EndeavourOS. Reasons here: https://github.com/arindas/manjarno/blob/main/README.md
