Ubuntu - Libicu52 Install (Not Working)

So I’m trying to install libicu52 through Terminal by entering:

sudo -s
apt-get install libicu52

and for some reason, it says unable to locate the package. Is it part of some sort of hierarchic required package? I kind of find it strange, since I can install it from the desktop, but doing it through Terminal doesn’t really seem to work.

Which version of ubuntu are you on?

uname -a

Also, you don’t need to open a root shell to use apt. You can just sudo before your command.
