I installed trixie from scratch with the 13.2 netinst just over
two weeks ago, my second such installation. To save bandwidth,
I copied the trixie packages saved from my first installation
into /var/cache/apt/archives: it's now a 6.7GB .deb collection.
As this laptop runs pretty much 24/7, I decided to install
apt-cacher-ng on it, rather than my usual workaday desktop.

Following the acng guide, I attempted to import my packages,
and got the same symptoms as reported here at #5. The opening
words, "Since the update to 3.7.5-1," gave me hope, though;
so I carried out the following operations:

1. Re-moved the package collection out of /v/c/acng/_import/
back into a safer location,

2. Removed apt-cacher-ng and its three dependencies that were
recently installed (/only/ purging the dependencies), but
see step 8,

3. Manually downloaded bookworm's version of apt-cacher-ng,

4: Attempted to install it, which required libc-ares2 in
addition as a dependency,

5. Manually downloaded (trixie's) libc-ares2, and installed
apt-cacher-ng and libc-ares2 together,

6. Moved the package collection back into /v/c/acng/_import/,

7. Import now worked.

I now have 5.2GB under debrep, and 1.7GB left behind in _import,
and the latter seems reasonable with there being 8 old chromiums,
4 old firefoxes, one old libreoffice suite and a linux-image
among the detritus. So,

8. apt-get upgrade which upgraded apt-cacher-ng. I left
libc-ares2 installed though it's currently redundant.
(Removing the three dependencies at step 2 was unnecessary.
Had this procedure not worked, I was going to remove acng
for the time being, and use a USB stick instead.)

As this bug has been open for 17 months, I hope this post
might be of use to somebody.

Cheers,
David.

The msintainer is AWOL. Right now I'm doing what I can to keep acng in
the archive but unless a debian developer steps up to salvage it then I suspect eventually this very useful package will die.

I don't use import but a I suspect ccdc24ae (SHA256 checksum support)
which I vaguely recall thinking was incomplete while looking at the
code.

Eventually I'll TAL but won't be soon.

Tim.
