Is a manual install of MySQL even possible?

So I attempted to peform a manul install of the latest MySQL using their APT Repository method which seems to take all the guest work out of installing the package.  I created a folder called download under admin home directory and ran MD5sum to ensure the APT repository package was legit.  The MD5 was confirmed to match to what's listed on their page: http://dev.mysql.com/downloads/repo/apt/

admin@RN626:~/downloads$ md5sum mysql-apt-config_0.8.0-1_all.deb
77903c9741895fb68408b4527367bca7 mysql-apt-config_0.8.0-1_all.deb 

I then went to install it and was denied due to not having superuser privilege.  Really?  So I tried using the SUDO command even though I already have SSH/Root priviledges and still no dice. I have not yet tried just installing the standalone package but believe it too would fail due to priviledges.  

So my questions are:

• How do I get superuser privileges?  
• I presume my permissions are limited by Netgear to reduce the chance of users messing up their NAS.  However, there has to be a way to backup core libraries/OS system and restore them should anything go wrong.  
• Does anyone at Netgear or otherwise have the ability to test manually installing MySQL or PHP and posting the results/procedure?  Granted everyone would use it at their own risk but it still would be super useful given the situation with the App store.  

admin@RN626:~/downloads$ dpkg -i mysql-apt-config_0.8.0-1_all.deb
dpkg: error: requested operation requires superuser privilege

admin@RN626:~/downloads$ sudo dpkg -i mysql-apt-config_0.8.0-1_all.deb
-bash: sudo: command not found
