We don't remove required dependencies. Just use another package which provides mongodb instead.

Can you take out the mongodb dependency please? The source mongodb package is the default mongodb dependency and is flagged out of date since 2020 and it doesn't even build. Thanks!

Build of mongo fails. This is e.g. https://bugs.gentoo.org/768339 which has been fixed months ago

    src/mongo/db/exec/plan_stats.h:214:10: error: 'optional' in namespace 'std' does not name a template type

@torben Thanks so much for the fix! https://localhost:8443 was inexplicably refusing connections, but adding

unifi.https.sslEnabledProtocols=TLSv1.2

to /usr/lib/unifi/data/system.properties got it working.

I reckon this should be done in the PKGBUILD, or at least suggested by it.

Additionally, as noted on later pages of comments, first installing mongodb-bin avoids many hours of compilation time for the mongodb package.

Build fails with:

@code_xpert: I had the same problem a while ago IIRC. The problem was related to the database configuration being invalid. I can't remember it precicley, but in essence I had two config files for the wired tiger/mongod engine present, an old and a new one, where the package got confused during upgrade. Look in the config directory if there is everything ok there or if anything is supscious. I can't find any remnants of this anymore, but it was somewhere in /var/lib/unifi/data (maybe subdir "db"). I think, back than I did reactivate the old configuration somehow and the system went running again. Right now, my mongod db directory does not contain much configuration anymore, seems, that the current systemd scripts work primarily by command line arguments.

@torben I tried your fix because I had the same problem, and it worked! Thank you!

@medicineman25 he made the changes at "/usr/lib/unifi/data/system.properties".

I have a problem too. When I go to localhost:8443, it says "Unifi Controller is starting up..." for a brief second, then it says "Database Migration in progress..." forever. Has anyone experienced this problem too? How could I possibly fix this?

Thanks.

Installed mongodb-bin 5.0.1-2. mongod crashes within seconds of restarting unifi.service with an out of memory error. Machine has 8GB of RAM and 8GB of swap.
