Where backends_debian pointed to a "bad" mirror: ftp.rediris.es so while I
thought I was retrieving the file from the mirror I wanted (ftp.gul.uc3m.es)
acng was actually trying to get it from ftp.rediris.es.
The fix was removing backends_debian and running dpkg-reconfigure apt-cacher-
ng
There are 2 problems with this as I see it:
· Regular user, like me, would expect that if you explicitly tell the mirror
you want to use in sources.list, you retrieve files from this specified one.
This is true, unless file is already in the cache, in which case doesn't
matter. I understand that remapping has precedence over user suggested mirror
(as per documentation) but I'm not sure whether this should be the default.
· I didn't tweak remap options so I assume those are the default ones, (find
attached acng.conf). For any reason ftp.rediris.es , which was the mirror I
formerly used until I stopped for its misbehaviour, remain on the
backends_debian flie. I'm not sure BTW, if I did any acng upgrade since the
change.
I guess there should be an automatic method that updates backends_debian
according to user suggestions, especially when faulty mirrors remain in there.
Additionally, even documentation explains this case, I had to reread it
several times to finally understand what Remap means. Sure I'm not that
brilliant, but maybe a rephrase of the remap section would help. I'll try to
think about this and come with some ideas.
Taking all the above into account, I assume this bug it's not such. I
acknowledge that this has been a "bad configuration problem". Still there are 4
issues raising from this, so I'll await for your opinion on each on them. I
wouldn't mind placing a bug report for each.
