Describe the problem

After upgrading to v0.55.0 I get this error in the management container:

2025-08-20T12:57:50Z WARN [context: SYSTEM] management/cmd/management.go:201: could not initialize geolocation service. proceeding without geolocation support: /var/lib/netbird/GeoLite2-City_20240305.mmdb could not be opened: error opening database: invalid MaxMind DB file

And then it will just restart.

Downgrading back to 0.54.x fixes the issue.

To Reproduce

Steps to reproduce the behavior:

  1. Upgrade management to 0.55.0
  2. Check the logs

Expected behavior

The management container should startup.

NetBird version

0.55.0

Additional context

@bcmmbaga commented on GitHub (Aug 20, 2025):

Hi @Kidswiss , the error occurs because of invalid GeoLite2 database files in /var/lib/netbird (e.g. GeoLite2-City*.mmdb, geonames*.db). To fix this you can remove the invalid files and restart the management service. On startup, it will automatically download fresh GeoLite2 databases.

If you’re not sure which files to delete, please share the output of:

ls -l /var/lib/netbird

This will show us which GeoLite2 database files are present and we can guide you on exactly which ones to remove.

Hi @bcmmbaga

Thanks that worked!

I checked the changelog for 0.55.0 in more detail now and found: https://github.com/netbirdio/netbird/pull/4362

So I guess my database might have been corrupted for a long time and only now it started to throw the error?

Also, maybe doing a re-download of the database in case it's corrupted might make things a bit more stable.
