[Impact]
xdiagnose requires root permission to run, otherwise it crashes when it tries
to update the grub configuration.
This is showing up in the automatically collected errors:
https://errors.ubuntu.com/bucket/?id=%2Fusr%2Fbin%2Fxdiagnose%3AIOError%3Amove%3Ahandle_enable_apport%3Amove%3Acopy2%3Acopyfile
This shows the issue affects precise, quantal, and raring users, with
quantal being the most heavily affected.
+
+ [Testcase]
+ 1. Open xterm window
+ 2. Run `xdiagnose` as a non-root user
+ 3. Change some grub settings
+ 4. Click apply
+
+ Expected behavior: At step 2, remind user to run app as superuser.
+ Actual behavior: Crashes at step 4
[Fix]
A partial fix was added to the .desktop file, which made xdiagnose use
gksu/pkexec to request root permissions when run from the menus. However,
xdiagnose can also be run directly from X terminals. To address this case it
needs to check if it's run as root at startup, and if not print an error so the
user knows to run it with sudo or similar.
[Regression Risk]
The patch is very trivial and non-invasive so not likely to cause
regressions. Also, the application is for diagnostic purposes so the impact of
a regression in this tool is pretty minor.
[Original Report]
Hello
Launching the xdiagnose gui from the icon, it start, accept the checkboxes
variation but when i click apply it don't require me the password to read the
grub file.
Launching it from terminal it return the permission denied error.
Thanks
Fabio
