I'm running Xubuntu 14.04 on an old dell tower I pulled out of my closet to use ruby on rails with.
I was attempting to install ruby and rails but none of the installs took. My system is updated and upgraded. I then tried to switch to ubuntu 15.04 but the terminal wouldn't allow for this either. I decided to change to ubuntu 15.04 through the software center but I couldn't find the software center. I tried to install it but the terminal out put the same as everything else, something like "can't find files".
I then realized after trying to search for the software center that it is on the drop down named as "\s\s\svb". When I try to run it I only get an alert stating "Failed to execute command "/usr/bin/software-center%u".
I have tried to download ubuntu 15.04 on my windows laptop and load it to a flash drive using unetbootin but It will not run on my tower. I can't upgrade desktops through the terminal, or apparently find or install any files. I can't access the software center either. I'm not very experienced with linux and I only want to learn ruby on rails which isn't something I am able to do very easily on windows. Any ideas or solutions would greatly appreciated.
