An errormessage generated by Error::Errno (or Error::WarningE) is:
E/W: generic apt error - method used (errno: strerror() with "exact" reason)
The plain reason is that we have a waste amount of possibilities why a file
is not readable: doesn't exist, broken link, insufficient rights, …
writing a message for all of them in APT would be insane.
On the other hand some of the error messages given by strerror() aren't
verbose and/or exact enough to be used alone, so the middle way was chosen.
(I think the Methodname is their to enable Error to do something special
with certain failures as noted in the Description of the file, but it is
unused so far - but from time to time useful to map (translated) error
messages to their untranslated equivalent in bugreports.
I have convert now this and a few other calls from FileExists() to
DirectoryExists() which was added recently to check if it is really a
directory and not a file, but this doesn't change much…
Any further suggestions?
Best regards,
