[Bug 1701648] Re: app never starts in Ubuntu 16.04.2 due to missing python-cairo module

[Hans Joachim Desserud]

Added SRU description, though also found bug 1702367 which affects 16.04
and later... Wish I found that earlier :/

** Description changed:

+ [Impact]
+ 
+   * smartshine has an insufficient list of dependencies, so users might
+ end up in a situation where required dependencies happens to not be
+ installed.
+ 
+ 
+ [Test Case]
+ 1. Install smartshine
+ 2. Verify that python-cairo and python-gi are installed.
+ 3. Verify smartshine starts without any dialogs with errors.
+ 4. Attempt to uninstall either python-cairo or python-gi (try one at a time). When attempting to uninstall either libarary, smartshine should be listed as "will also be removed".
+ 
+ Before the fix, both libraries could be removed, at which point
+ smartshine would print an error message in the terminal.
+ 
+ 
+ [Regression Potential] 
+ There should be no changes in package itself, only additional dependencies have been added. Thus, more packages are installed. 
+ 
+ I was clicking around in the application and found bug 1702367 though,
+ which is a bit more severe than this one. Even though it is possible to
+ run the application, it won't do much. Note that this occurs prior to
+ the patch, so it is not a regression.
+ 
+ 
+ [Original report]
+ 
  In Ubuntu 16.04.2 when is installed smartshine from the official repository it does not start.
  If the app is started by the GUI there is no error , if the app is started by the terminal is shown a generic error "An error occured. Python or one of its sub modules is absent..."
  The error can be solved simply installing python-cairo from the official repository.
  ps: sorry for English not perfectly correct
