I've got a real brain-boggler here. Running mist no issue on one machine Ubuntu 14.04.4 KDE, identical version on another machine (cough) chromebook, chrooted, and the executable won't launch. I'd also note that it's not the hardware because I have mist running on other heavy chrooted distros, namely Unity and Mate. Any thoughts?
ldd is a beautiful Beautiful command (checks binary dependencies and what's missing)
libgconf2.so.4 not found **sudo apt-get install libgconf2.so.4**
Fetches from a google chrome server... Don't have chrome on machine Mist binaries fail. Do on the machine Mist works.
Low and behold Mist binaries now work with this dependency
In a standard install of 19.10,
libgconf2.so.4 might not be available, so running
sudo apt-get install gconf2 is a recommended solution, which might solve your issue straight away.
In my case, I had to additionally run
sudo apt --fix-broken install to clean up a (previously?) broken install of
gconf2. I am not sure if this last step by itself might not have solved the problem immediately.
