Description of the bug updated to provide error messages. Please tell me
which log to check to know what caused the `Could not calculate the
upgrade` message.

** Description changed:

- A error message appeared saying the upgrade cannot continue and will
- stop, asking me to report this problem with `ubuntu-bug ubuntu-release-
- upgrader-core`.
+ The system asked me for an upgrade, I accepted.
+ 
+ I first had this information message:
+ ```
+ Third party sources disabled
+ 
+ Some third party entries in your sources.list were disabled. You can re-enable them after the upgrade with the 'software-properties' tool or your package manager.
+ ```
+ 
+ I validated the popup and the upgrade started but then I had this
+ message:
+ 
+ ```
+ Could not calculate the upgrade
+ 
+ An unresolvable problem occurred while calculating the upgrade.
+ 
+  This can be caused by:
+  * Upgrading to a pre-release version of Ubuntu
+  * Running the current pre-release version of Ubuntu
+  * Unofficial software packages not provided by Ubuntu
+ 
+ If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.
+ ```
+ 
+ I never used a pre-release of Ubuntu and I'm not upgrading to a pre-
+ release. I don't know how to check what "unofficial package" I have and
+ which could cause that. My /etc/apt/sources.list looks clean:
+ 
+ ```
