David,
Some time back there were some peeps that encountered similar troubles.
There was one fellow that developed a procedure for handling this
problem, and I haven't seen it discussed anywhere else except on the
Mandrake lists. This recovery procedure would be a fantastic thing to
be worked into the Mandrake distro as a recovery tool, cause I don't
think any other distro has it. Anyways, I searched the archives and dug
it up:
_____________________________________________________________________
On one of my Mandrake Linux systems, I had once this problem:
[pascal@hermes pascal]$ su
Password:
[root@hermes pascal]# rpm -q -a
failed to open //var/lib/rpm/packages.rpm
rpmQuery: rpmdbOpen() failed
[root@hermes pascal]# rpm --rebuilddb
failed to open //var/lib/rpm/packages.rpm
[root@hermes pascal]# rpm --initdb
[root@hermes pascal]# rpm -q -a
failed to open //var/lib/rpm/packages.rpm
rpmQuery: rpmdbOpen() failed
[root@hermes pascal]# rpm --version
RPM version 3.0.3
Well, clearly the RPM database was completely out of usage. I had to
rebuild it.
You may think that it's simply a matter of using :
rpm --rebuilddb
However, I learned that --rebuilddb is REALLY AND COMPLETELY USELESS.
Maybe the
authors and contributors to rpm could take some idea from this NFAQ to
actually
implement a true --rebuilddb option.
The main idea of the process is to use:
rm -f /var/lib/rpm/* ; rpm --initdb
and:
rpm -i -v --nodeps --noscripts --notriggers --excludepath /
packages...
to fill a package database without really installing anything (not
overriding
installed files, not running any script, ...). This is done in the
seventh step;
everything before I made to recover a list of installed packages.
This is not perfect, since some packages I have upgraded or modified the
sources
and upgraded. I should have checked for /usr/src/RPMS too; I'll update
the
database later by hand to synchronize it with the handful of packages I
touched
after the initial installation.
