Hi!
I am using nixos-24.11 packages in my flake. I have
services.unifi = {
enable = true;
unifiPackage = pkgs.unifi8;
# mongodb-7_0 is not available precompiled and compiling takes dozens of GB RAM and disk space
# use mongodb-ce instead:
mongodbPackage = pkgs.mongodb-ce;
openFirewall = true;
};
However the unifi service never fully starts. I can not reach the unifi controller webinterface on port 8443.
/var/log/unifi/server.log keeps repeating those lines:
[2025-04-19T17:49:18,490+02:00] <mongod-tail> WARN mongo - Mongo log not found during startup
[2025-04-19T17:49:18,591+02:00] <mongod-tail> WARN mongo - Mongo log not found during startup
[2025-04-19T17:49:18,691+02:00] <mongod-tail> WARN mongo - Mongo log not found during startup
[2025-04-19T17:49:18,792+02:00] <mongod-tail> WARN mongo - Mongo log not found during startup
[2025-04-19T17:49:18,892+02:00] <mongod-tail> WARN mongo - Mongo log not found during startup
[2025-04-19T17:49:18,974+02:00] <mongo-db> WARN mongo - Stop listening to Mongo logs after process has exited
[2025-04-19T17:49:18,974+02:00] <mongo-db> INFO mongo - Database process stopped, code=132
So I wanted to try to downgrade the mongodb package from 8.x to 7x and see if that works arround the issue. My problem is I am new to nixos and don’t know how to specify the mongodb-ce version for unifi.
This didn’t work: mongodbPackage = pkgs.mongodb-ce.override { version = "7.0.14"; };
Can I only do this via the lock file?
