Hello! So, I'm relatively new to Linux and its environment. The other day I wanted to move some files around remotely, but the system wouldn't let me. Whether it be with WinSCP or PuTTY I couldn't move files, I was able to move them in PuTTY later by using "sudo". It didn't use to do this before so it would be helpful to know what changed everything so I can prevent/fix it in the future. For now, I fixed the problem by installing a new distro, but some lessons would be helpful.
