How do I change application installation directory?

Today I installed OpenSUSE tumbleweed on my computer from a USB flash drive. During the install process, I selected my main hard drive and chose to use the entire disk and erase all partitions. However, after logging in I went to install an app. By this point I had unplugged my USB flash drive. So when I went to install the app, I got the error message that it couldn’t install because it couldn’t find my USB drive. So I am assuming somehow the install path for applications got set to my USB flash drive. Any way to correct this?

go to yast repository management and disable or delete the usb as a repository, you don’t need it after install.

As I_A already mentioned, this is just a local media repository that needs to be disabled or removed. It was set up at install time as you installed via USB media. You can do this via YaST or zypper (CLI).
