I think you'll find that
was a 'real' suggestion. Quite simply, the dependency you need isn't in the repositories for 'Disco Dingo'.
The suggested steps ought to help somewhat. No guarantees, but they should help.
------------------------
If that doesn't work, you could always try this:-
https://ubuntu.pkgs.org/18.10/ubuntu...amd64.deb.html
It's the download page for that particular dependency from the previous release, Cosmic Cuttlefish, over at
pkgs.org. I'm assuming you're 64-bit with this, yes?
The download is further down that page. You
can install this directly, by clicking on the .deb, but I'd advise installing it via gDebi. You can get gDebi from the repos:-
Code:
sudo apt-get install gdebi
gDebi just seems to handle dependencies of .deb packages better than anything else.
This is the 'manual' way we often resort to in 'Puppy' Linux, and is the one thing that always astounds me about the package management system in mainstream distros. The package you very often need is available, quite freely, in
another repo somewhere.....but because it's not an 'official' repo, use of such is frowned upon. The system won't let you use something from a foreign repository, because
that's not kosher!
Give it a try. Can't hurt. It may not be the 'officially approved' way of doing things, but it'll get you what you want. Of course, you may end up going on a 'lib-chase', as further dependencies are uncovered.....but
pkgs.org is a very good resource for all this.
(If it's a weather app you're after, you could do worse than to give this a try:-
https://jackd248.github.io/temps/
'Temps' - an Electron-based weather app, that looks very like a mobile phone app. It works very, very well, though; I've been using it for a couple of years now.)
It's a single binary, which you can run from literally anywhere.....
