I just finished installing Debian 8 (Jessie) and tried to make a directory in lib/firmware, because there was a file missing (rtl8723befw.bin) in the installation, and it says

mkdir: cannot create directory rtlwifi: Permission denied

I tried putting sudo on the front, but then it returns:

bash: sudo: command not found

When trying to install sudo with apt-get install sudo or even apt-get update it returns:

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

I am really at a loss of what to do. All the solutions that I seem to find for the latest error is to use sudo, but I don't even have that.
