[Bug 1802529] [NEW] insufficient/wrong info in diagnostic

[david braun]

Public bug reported:

When starting the update-manager manually I get a diagnostic saying

    Failed to download repository information
    Check your internet connection

Two things are wrong with this diagnostic

    1. There isn't enough information for me to discover the cause.
    2. It's a lie.

There is nothing wrong with my internet connection because the update-
manager has successfully downloaded information from several
repositories by the time this diagnostic occurs. Telling me to check my
internet connection is not the right suggestion.

There is enough information for me to figure out what is causing this
error. The location of a log ("see xxxx for more information") or the
URL that caused the problem would have been more helpful. This happens
rarely enough that I don't remember if or where logs for the update-
manager exist.

BTW - the man page for update-manager mentions "aptitude" don't you mean
"apt"?

EXPECTED
The manager not to trip over any repositories and suggest updates (if any)

Happened
Useless diagnostic about a bad internet connection.
