[SOLVED] Issues when Updating (Arco Linux 19.11.3)

Hello,

I just installed Arco Linux. It's my first Arch based distro. After installation, I wanted to update the system. I am asked several questions like:
:: Replace arcolinux-applications-git with arcolinux_repo/arcolinux-local-applications-git? [Y/n] Y
:: Replace arcolinux-local-git with arcolinux_repo/arcolinux-local-xfce4-git? [Y/n] Y

When I answer all with No, then the update continues and everything is fine. But whenever I want to update or install anything, I'm asked these questions again. When I answer yes, the update process stops with an error message. I can't install anything with the GUI software installer, I always get the attached error message.

Can anybody help me?

(PS: I think Arco has an own forum at arcolinuxforum.com but since yesterday I can't access it. I am located in Vietnam and somehow it seems to be blocked.)
