without any output why it won't start it's a bit hard to help.
I extracted Singularity to /home/lockheed/downloads and I simply start it via Terminal (start Terminal first, it's in System Tools section) which should bring you to your home directory:
Code:
lockheed@lovelock:~$
This means: username/loginname (lockheed, hostname (lovelock), current folder (~ is a shortcut for /home/username), prompt ($ means usually normal user, # would mean admin mode (called "root" - never work in root mode unless doing admin stuff)
then simply start the viewer by typing:
Code:
lockheed@lovelock:~$ downloads/Singularity_1.6.0_3/singularity [ press Enter]
of course, use your extract path and file name.
Then the Terminal should stay open and give a lot of text what is actually happening.
Hint: for lazy typing, there is an auto complete option when the path is clear, try using the TAB key when you type:
Code:
lockheed@lovelock:~$ Down[press TAB key and look what happens]
In case the path is not clear, press TAB twice to see possible options basing on what you typed so far. Also works with commands and file names.
Hint 2:
The Terminal is your friend.
