"Package does not exist" error is unhelpful for updates

[Matthew Paul Thomas]

update-manager 1:0.181, Ubuntu Ringtail

It is possible for Software Updater to produce a "Software Updater" alert: "Package does not exist" "Check the spelling of the package name, and that the appropriate repository is enabled."

That might be appropriate when a third-party application asks for installation of a particular package. But it isn't really appropriate when installing updates. The updates you're installing are updates that were previously shown in Software Updater because they *were* available.

So, Software Updater needs to special-case the error message in this situation. Is it just that the package version has disappeared from the repository betwen the time Software Updater opened, and the time you chose to install it? Or is there another cause?

This error message actually comes from aptdaemon's enums.py.

    ERROR_NO_PACKAGE: _("Check the spelling of the package name, and "
                        "that the appropriate repository is enabled."),
