** Description changed:

- When trying to uninstall a (customly built) DKMS module using "dkms
- uninstall -m my_module -v 1.1" dkms fails with exit code 1 and doesn't
- print an error message.
- 
- The problem occurs with the invocation of the function "have_one_kernel"
- in the /usr/sbin/dkms script. This function doesn't evaluate to 0 as it
- should, when all conditions are met (as with the command specified
- above).
+ [Impact] 
+ This bug makes it impossible to uninstall DKMS modules. When trying to uninstall a DKMS module using "dkms uninstall -m my_module -v 1.1" dkms fails with exit code 1 and doesn't print an error message.
  
  The commands
  "dkms uninstall -m my_module -v 1.1 --all"
  and
  "dkms uninstall -m my_module -v 1.1 -k 3.2.0-57 -k 3.5.0-44"
  fail as expected with the resp. error messages and exit codes in function "have_one_kernel".
+ 
+ The proposed patch is a backport from upstream.
+ 
+ 
+ [Test Case]
+ A test script has been added in comment https://bugs.launchpad.net/debian/+source/dkms/+bug/1261116/comments/8.
+ 
+ To reproduce the bug:
+ 1. Take any dkms package.
+ 2. Copy the package into the dkms src folder /usr/src/<package_name>-<package_version>.
+    <package_name> and <package_version> can be found in dkms.conf in the package.
+ 3. Add the dkms module:
+    dkms add -m <package_name> -v <package_version>
+ 4. Build the dkms module:
+    dkms build -m <package_name> -v <package_version>
+ 5. Install the dkms module:
+    dkms install -m <package_name> -v <package_version>
+ 6. Try to uninstall the dkms module:
+    dkms uninstall -m <package_name> -v <package_version>
+    Here, dkms fails with exit code 1 and without emitting an error message.
+ 
+ 
+ [Regression Potential] 
+ All client code that uses the "dkms uninstall" command and relies on it failing are candidates for regressions.
