How to do recovery rpm database?

Hey Martin,

Follow the steps below to recover your rpm database –

First, you would need to backup your existing database (just in case); this is located in /var/lib/rpm and depending on your distribution the content of the folder might look like this:/var/lib/rpm-rw-r–r– 1 rpm rpm 5464064 Feb 9 04:17 Basenames-rw-r–r– 1 rpm rpm 12288 Feb 3 05:03 Conflictname-rw-r–r– 1 root root 0 Aug 25 02:48 __db.000-rw-r–r– 1 root root 24576 Aug 14 04:02 __db.001-rw-r–r– 1 root root 1318912 Aug 14 04:02 __db.002-rw-r–r– 1 root root 450560 Aug 14 04:02 __db.003-rw-r–r– 1 rpm rpm 1982464 Feb 9 04:17 Dirnames-rw-r–r– 1 rpm rpm 5259264 Feb 9 04:17 Filemd5s-rw-r–r– 1 rpm rpm 24576 Feb 9 04:17 Group-rw-r–r– 1 rpm rpm 28672 Feb 9 04:17 Installtid-rw-r–r– 1 rpm rpm 45056 Feb 9 04:17 Name-rw-r–r– 1 rpm rpm 31707136 Feb 9 04:17 Packages-rw-r–r– 1 rpm rpm 339968 Feb 9 04:17 Providename-rw-r–r– 1 rpm rpm 106496 Feb 9 04:17 Provideversion-rw-r–r– 1 rpm rpm 12288 Dec 2 08:45 Pubkeys-rw-r–r– 1 rpm rpm 253952 Feb 9 04:17 Requirename-rw-r–r– 1 rpm rpm 167936 Feb 9 04:17 Requireversion-rw-r–r– 1 rpm rpm 86016 Feb 9 04:17 Sha1header-rw-r–r– 1 rpm rpm 49152 Feb 9 04:17 Sigmd5-rw-r–r– 1 rpm rpm 12288 Jan 15 21:09 Triggername

Then just backup all the /var/lib/rpm folder to its original state:cd /var/lib tar czvf rpmdb.tar.gz rpm

Finally, rebuild the rpm database:cd /var/lib/rpm rm -f __db* rpm –rebuilddb -vv

After this, your rpm commands should be working again.

Cheers.

If your RPM database got suddenly corrupted for no reason, here’s how you can fix it. Take note: it is not always possible to fix errors in an RPM database especially if you don’t have a backup of your database. But sometimes it is possible. You should have rpmdb tools installed.

First, bring your system to single-user mode to prevent further damage to the database and also this makes the backup or restore process easy. Next, you need to remove “/var/lib/rpm/__db*” files to prevent stale locks. To do this, do the following:

After this, rebuild the RPM database:

See if you are still getting any errors after this. In case this doesn’t fix the problem and you are still getting errors, try the following commands if they’ll work:
