Unable to install Conduktor - Depends: libglx0 but it is not installable

Question

While installation I am having package conflicts. This is the response I am receiving.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

Answer 1

It seems Conduktor does not support Ubuntu 16.04, the libglx0 library is only available starting from bionic (18.04 LTS): https://packages.ubuntu.com/search?lang=en&keywords=libglx0&searchon=names

Answer 2

For anyone who is having problens with Conduktor on Ubuntu 20:

Ubuntu 20 updated from libffi6 (required by Conduktor) to libffi7, so you'll end up with this error:

$ sudo apt install ./Conduktor-2.7.5.deb

You can fix it this way:

• download libffi6 here http://mirrors.kernel.org/ubuntu/pool/main/libf/libffi/libffi6_3.2.1-8_amd64.deb
• instal it: $ sudo apt install ./libffi6_3.2.1-8_amd64.deb
• now, with success, install Conduktor: $ sudo apt install ./Conduktor-2.7.5.deb
