Package: dpkg
Version: 1.15.4ubuntu2
Severity: normal
I know I saw this on Ubuntu, but I'm submitting it here because I'm
pretty sure the issue exists in Debian and a fix upstream seems best.

dpkg: Fails to install packages if one package's .list file is broken
The wish is for ability to regenerate corrupted .list files.
More details:

PROBLEM:
/var/lib/dpkg/info/update-manager.list became unreadable somehow, but
the error message aptitude or dpkg emitted was confusing. 1) it needs a
leading newline and 2) it should be more clear about what file is broken.
SAMPLE (confusing, esp. the "90%dpkg" had me scratching my head for a
while):
# aptitude full-upgrade
Reading package lists... Done
[...]
(Reading database ... 90%dpkg: unrecoverable fatal error, aborting:
failed in buffer_read(fd): files list for package `update-manager':
Input/output error
E: Sub-process /usr/bin/dpkg returned an error code (2)
[...]
# dpkg -r xserver-xorg-input-all
(Reading database ... 90%dpkg: unrecoverable fatal error, aborting:
failed in buffer_read(fd): files list for package `update-manager':
Input/output error
TRANSLATION: it should say something like (note added newline):
(Reading database ... 90%
dpkg: unrecoverable fatal error, aborting:
failed in buffer_read(fd): unable to read file
'/var/lib/dpkg/info/update-manager.list' for package `update-manager':
Input/output error
WORK-AROUND: to re-create the .list file, where the broken package is
"update-manager" and a local copy exists in the cache.
# dpkg --no-debsig --no-triggers --force-all -r update-manager
# dpkg --no-debsig --no-triggers --force-all -i
/var/cache/apt/archives/update-manager_1%3a0.126.6_all.deb
# aptitude reinstall update-manager
I'm not 100% sure that both --no-debsig and --no-triggers are necessary;
I had them so I used them. Note that technically I was on an Ubuntu
Karmic system, but in theory this should work fine for Debian too.
Substitute 'apt-get' instead of 'aptitude' if that's what you normally use.
Later,
JP

software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
