Hi,

dput currently prints a distracting backtrace (with colors and some parts in
bold) when an upload to a host is not allowed because a distribution name
mismatch.

It'd be better if it printed the error message and no backtrace.

Example output:


% dput pdns-recursor_4.8.8-1+deb12u1_source.changes
Trying to upload package to ssh-upload

Traceback (most recent call last):

    ...<3 lines>...
            options.allow_unsigned_uploads,
            options.debug)

    ...<2 lines>...
            ).format(**vars()))
dput.helper.dputhelper.DputUploadFatalException: Error: uploading files for distribution bookworm-security to ssh-upload not allowed.

(Note that "dput.helper.dputhelper.DputUploadFatalException" is in bold purple,
various parts of the backtrace are in red, etc.)

I would have expected it to look like this:

% dput pdns-recursor_4.8.8-1+deb12u1_source.changes
Trying to upload package to ssh-upload
