on kubuntu 20.04

[mhamadalkhubbi]

I got this when installing Package com.github.babluboy.nutty is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'com.github.babluboy.nutty' has no installation candidate any solution?

Thanks for raising this issue. Here is Nutty's launchpad build page for the stable version: https://code.launchpad.net/~bablu-boy/+archive/ubuntu/nutty.0.1

Try with the following PPA: sudo add-apt-repository ppa:bablu-boy/nutty.0.1 sudo apt-get update

Or try the instructions here to build from source, that should work. https://babluboy.github.io/nutty/#install
