Bug#45695: apt: apt-get update fails with apt-cdrom
Package: apt
Version: 0.3.13
Severity: normal
I run into serious trouble with apt 0.3.13 when trying to use the
Linux-Central Slink 2.1r1 CDs.
Here's what I did:
- remove /etc/apt/apt.conf
- remove /etc/apt/sources.list and create a new empty one
- remove /var/state/apt/cdroms.list
- remove /var/state/apt/lists/*
So I have a clean environment.
Now I do a "apt-cdrom add" to add the binary CD 2 of the above
mentioned disk set. This seems to work correct:
------------------------ cut ----------------------------------
# apt-cdrom add

Repeat this process for the rest of the CDs in your set.
------------------------ cut ----------------------------------
This creates a /var/state/apt/cdroms.list with the following contents:
------------------ cdroms.list --------------------------------
CD::437011adaf8f9b2306881fab43cdc877-2 "Debian GNU_Linux slink (2.1) 2_4 main binary-i386 section 2, contrib SAM19990306";

------------------ cdroms.list --------------------------------
And the following /etc/apt/sources.list:
------------------ sources.list -------------------------------
deb-src "cdrom:Debian GNU_Linux slink (2.1) 2_4 main binary-i386 section 2, contrib SAM19990306/" debian/dists/frozen/contrib/source/

deb "cdrom:Debian GNU_Linux slink (2.1) 2_4 main binary-i386 section 2, contrib SAM19990306/" debian/dists/frozen/main/binary-i386/
------------------ sources.list -------------------------------
This looks quite good, but when I run "apt-get update" now, the cache
files aren't accessible:
---------------------- cut ------------------------------------

"strace -e stat apt-get update" tells me that apt-get tries to access
the above files using stat() (with correct names, no longer problems
with double "_" or something like this), but what does this "Method
gave a blank filename" mean?
Then I tried the same as above (with an empty cdroms.list and
sources.list) with a potato CD which I burned myself. This CD has a
directory /debian/binary-i386 with all the packages in it and a
Packages file which was created with
dpkg-scanpackages . /dev/null > Packages
in the /debian/binary-i386 directory.
This gives me another strange message:
---------------------- cut ------------------------------------
# apt-get update
E: The method driver /usr/lib/apt/methods/Packages.gz could not be found.
E: The method driver /usr/lib/apt/methods/Release could not be found.
---------------------- cut ------------------------------------
The Linux-Central CD worked with apt 0.3.11 without any problems while
the self burned potato CD caused some problems (see #43830), which I
was able to work around with 0.3.11. I didn't fully test 0.3.12, but
I fear that it also was broken for apt-cdrom like 0.3.13 is.
I hope that the above wasn't too much information but enough to find
the center of the problem, which makes apt-cdrom completely unusable
here.
Ciao
