I installed MongoDB on Ubuntu (23.04) based on this tutorial. Immediately after installing it, I found out that its systemd service doesn't work. Here's the error I got:
# systemctl status mongod
× mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; enabled; preset: enabled)

I tried restarting the service, but same result. I tried installing MongoDB on Fedora 38, and it worked perfectly. After installing it, I started the service, and it was running. But on Ubuntu 23.04, It failed.
mongod service does NOT start.
And here's the contents of the log file (mongod.log). (the following output was repeated like a dozen times in the log file)

P.S. I tried this and this (setting ulimit -n 64000) from stackoverflow, but it didn't work.
