DB_VERSION_MISMATCH when attempting to manage packages

[0xADD1E]

Describe the bug When attempting to install a package:

error: db5 error(-30969) from dbenv->open: BDB0091 DB_VERSION_MISMATCH: Database environment version mismatch
error: cannot open Packages index using db5 -  (-30969)
error: cannot open Packages database in /var/lib/rpm

To Reproduce

Unknown. I haven't been doing anything abnormal, so far as I know.

I also encountered this when attempting to upgrade from 30 to 31, but I opted to fix that by completely reinstalling the application. I would really rather not do that here.

Basic Troubleshooting Checklist

• [x] I have searched Google for the error message.
• [x] I have checked official WSL troubleshooting documentation: https://docs.microsoft.com/en-us/windows/wsl/troubleshooting#confirm-wsl-is-enabled.

• [x] I have searched the WLinux issues page: https://github.com/WhitewaterFoundry/WLinux/issues.
• [ ] I have reset WLinux: Settings->Apps->Apps & features->WLinux->Advanced Options->Reset.
• [ ] I have disabled and re-enabled WSL in Windows Features.
• [ ] I have run Windows 10 updates and restarted.

Hello @0xADD1E

Try this

sudo dnf upgrade --refresh rpm glibc
sudo rm /var/lib/rpm/.rpm.lock
sudo dnf upgrade dnf

Thanks! That resolves that issue!

[0xADD1E]

# dnf upgrade --refresh rpm glibc
...
Dependencies resolved.
Nothing to do.
Complete!

# rm /var/lib/rpm/.rpm.lock
# dnf upgrade dnf
...
Dependencies resolved.
Nothing to do.
Complete!

And then, attempting to install a new package succeeds. Was it really just the lockfile? or did the dnf commands do something that they're not mentioning?

If the former, do you think there's a case for this being an upstream issue with rpm's error messages?

[0xADD1E]

In either case, thank you for your help!

Just for reference, I just encountered this same issue. Had not had issue since I installed FedoraRemix on this PC in Oct 2019. I updated my PC to 2004, upgraded to release 32, and issue began. Not sure exactly what caused it, but the same resolution fixed it.

[crramirez]

This error is really erratic, this happened to me once. We don't know how to reproduce it or which is the cause. We create a script called upgrade.sh that takes care of it. Just run it every time that you want to call dnf update or very time when you see this error.

Following only @crramirez 's suggestion, still have the following (on CentOS Linux release 8.5.2111)

RPM: error: db5 error(-30969) from dbenv->open: BDB0091 DB_VERSION_MISMATCH: Database environment version mismatch
RPM: error: cannot open Packages index using db5 -  (-30969)
RPM: error: cannot open Packages database in /var/lib/rpm

but then after that, having run sudo rpmdb --rebuilddb it seems to work.

rpmdb --rebuilddb worked for me too, thanks! I didn't have to use sudo since I was already running as root
