Since 1:2.0, debmirror fails with "Duplicate dist hardy."  Here's the command
line:

debmirror --progress --verbose --host=us.archive.ubuntu.com --root=/ubuntu --dist=hardy,hardy-security,hardy-updates --section=main,restricted --method=http /media/mirror/hardy

The fix to #426170 in 1:1.0 broke hardy for the same reason it broke
experimental--the suite and codename are the same in the Release file.  I hoped
that the fix to #542929 solved the problem with hardy too, but it seems it
didn't.  I haven't had time to digest the code yet so that's as much as I can
say right now.

I know being able to mirror Ubuntu repositories might not be a priority so I'll
try to find time to make a patch.

Thanks!
Dave

Can you try with the following change?

 sub split_dist {
   my $dist = shift;
-  my ($dist_raw) = ($dist =~ m:^([^/]+)/?:);
-  $dist =~ m:^[^/]+(/.*)?$:;
+  my ($dist_raw) = ($dist =~ m:^([^-/]+)[-/]?:);
+  $dist =~ m:^[^-/]+([-/].*)?$:;
   my $dist_sdir = $1 // "";
   return ($dist_raw, $dist_sdir);
 }

Untested, but I think it should fix things for you.

Cheers,
FJP

After looking at Ubuntu's Release files I don't think that's going to
work. Please try the attached patch instead.

There's a closing brace missing in that patch, but otherwise it works OK
for me in a dry run. So I'll just upload the fix.

We believe that the bug you reported is fixed in the latest version of
debmirror, which is due to be installed in the Debian FTP archive:

debmirror_2.1.dsc
  to pool/main/d/debmirror/debmirror_2.1.dsc
debmirror_2.1.tar.gz
  to pool/main/d/debmirror/debmirror_2.1.tar.gz
debmirror_2.1_all.deb
  to pool/main/d/debmirror/debmirror_2.1_all.deb



A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 544132@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Description:
 debmirror  - Debian partial mirror script, with ftp and package pool support
Closes: 153680 156564 422100 544132 544139
Changes:
 debmirror (1:2.1) unstable; urgency=low
 .
   * Fix location of debmirror.conf. Closes: #544139.
   * Don't display download speed if rsync is used. Closes: #422100.
   * Support mirroring specific additional files from specific locations on
     the mirror: trace files, ./doc, ./indices and ./tools. The transfer
     method used for this is always rsync, irrespective of what method is
     specified in the --method option. Closes: #153680, #156564.
   * Ubuntu uses an identical Codename for different suites, so just ignore
     it and use the Suite instead. Closes: #544132.

This is still an issue with other Ubuntu-like archives, i.e.
archive.canonical.com, which I mirror internally for bandwidth-saving
reasons.

I'm using this hacky patch, but a more general solution would be great:

My guess is that this ugly hack was only needed to hande the transition
in 1:1.0 when existing mirrors had directories moved around. I suspect
if enough of that transition code was removed the hack could be gotten
rid of.
