Package ipython is not available but is referred to by another package.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
conduktor : Depends: libglx0 but it is not installable
E: Unable to correct problems, you have held broken packages.
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

The following information may help to resolve the situation:
The following packages have unmet dependencies:
conduktor : Depends: libffi6 but it is not installable
E: Unable to correct problems, you have held broken packages.
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
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
This command helped me:

Following this guide but unable to install cfdisk.
sudo apt-get install cfdisk

This is because the cfdisk utility is not shipped in a cfdisk package but in the util-linux package.
aptitude install util-linux
