I need some help with my MongoDB installation on a clean, fresh Ubuntu 12.04 LTS server with no nonsense installed. I thought it would be a piece of cake, but I got some errors and the Ubuntu-forums didn't had the answer I was looking for.
Before I started with the actual installation of MongoDB, I wanted the server to be up-to-date, so I typed:
$ sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade
I went to to website from MongoDB (http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/) and followed their tutorial, so I typed:
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
$ echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
$ sudo apt-get update
$ sudo apt-get install -y mongodb-org
At this point I have MongoDB installed. Like we all know, in order to use MongoDB you need to start it using a terminal and after that you'll be able to connect with a seperated terminal/connection.
So, I typed:
ubuntu-user@ubuntu-vm:~$ mongo
MongoDB shell version: 3.0.1
connecting to: test
Server has startup warnings:

Ofcourse, I don't want to use stackoverflow right away, before doing my own investigation first. I went online to look for answers and I noticed that lots of people using "export LC_ALL=C" to fix the variable problem. I also tried using dpkg.
ubuntu-user@ubuntu-vm:~$ export LC_ALL=C
ubuntu-user@ubuntu-vm:~$ dpkg-reconfigure locales
root@ubuntu-vm:~# dpkg-reconfigure locales

Generation complete.
Apparently, that didn't work properly, so I needed to continue my search. I came up with another solution: edit the /etc/default/grub file with GRUB_CMDLINE_LINUX_DEFAULT="transparent_hugepage=never" and then I got this:
ubuntu-user@ubuntu-vm:~$ mongo
Failed global initialization: BadValue Invalid or no user locale set.
Please ensure LANG and/or LC_* environment variables are set correctly.
ubuntu-user@ubuntu-vm:~$ mongod
2015-03-27T12:56:19.085+0100 F CONTROL Failed global initialization:
BadValue Invalid or no user locale set. Please ensure LANG and/or LC_*
environment variables are set correctly.
So, practically I have no idea what went wrong. I looked all over the internet and couldn't find the exact answer I am looking for. I did a clean install just like the website said. A few months ago I did the same tutorial and everything was working perfectly, with version 2.6.x, this is 3.0.1.
Could you guys help me out? Any comments/tips/tricks will be sincerely appreciated :)
