Package Management - Can't seem to download packages? (Connection issues?)

Howdy all, I’m trying to follow along in Package Management on my Pwnbox, but I can’t seem to download packages using the commands in the lesson. It seems to be a connection issue, as far as I can tell. Below are images of what happens when I try to run the commands. (Melded together into one image because my account is too new for multiple, it seems.)

Using git to download nishang/wget to download strace

Does anyone know what I’m doing wrong/how I can fix this? I’ve already tried resetting my Pwnbox once. May be related to this topic, but I THINK this is a separate issue.

Any advice is greatly appreciated. :smiley:
