** Description changed:

+ [Impact]
+ 
+  * Unattended-upgrades crashes when initializing the cache preventing security updates to be applied.
+  * The fix prints an error message then exits
+ 
+ [Test Case]
+ 
+  * Observe
+ https://errors.ubuntu.com/problem/cb12eff1497c73b95a2a51f4213bc3f30f2ac4d5
+ not happening in fixed releases
+ 
+ [Regression Potential]
+ 
+  * The fix is simply catching the error and exiting, there is little
+ room for regressions. In the worst case u-u crashes differently when
+ printing the error.
