EDIT: No problem - I forgot to do a sudo apt-get update afterwards (D'oh!)
I had to reinstall Ubuntu 16.04 from scratch and when I came to install indi-full and kstars-bleeding I got back:
$ sudo apt-add-repository ppa:mutlaqja/ppa
Latest INDI Library and drivers!

$ sudo apt-get install indi-full kstars-bleeding

E: Unable to locate package indi-full
E: Unable to locate package kstars-bleeding

I've never had this before

EDIT: Another senior moment. I got impatient and installed Kstars from the Ubuntu software manager. WRONG!!! This caused the conflict when i then tried to install indi-full. So I removed everything then installed indi-full followed by kstars-bleding as per the instructions and all is well

Actually there is a problem:
$ sudo apt-get install indi-full

indi-full is already the newest version (1.2~201609021821~ubuntu16.04.1).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
indi-full : Depends: libindi1 (>= 1.2.0) but 1.1.0-1ubuntu1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Hmmm... this was what started me down a path that resulted in having to reinstall Ubuntu

Looks like you installed libindi1 from Ubuntu repo, then tried to use it from PPA. Debian divides INDI into several packages different from my way. At any rate, I'll add a "conflict" flag to my control file. Thanks for the report!

EDIT: SOLVED.


Today i install new Mint 18 kde
after add command:
sudo apt-add-repository ppa:mutlaqja/ppa

return this error:
Impossibile aggiungere il PPA: ''Questo PPA non supporta xenial''.

( English translate. impossible add this PPA: "This PPA not support xenial". )

Thx.
