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.
