Error running package.sh: dpkg-deb: error: control directory has bad permissions 777 (must be >=0755 and <=0775)

I tried installing via compiling, but I found a few issues.

wireguird: cleaning...
rm: cannot remove './build/wireguird_amd64.deb': No such file or directory
wireguird: building go binary...
./package.sh: line 7: go: command not found
wireguird: copying icons...
wireguird: building debian package...
mkdir: cannot create directory ‘./build/’: File exists
dpkg-deb: error: control directory has bad permissions 777 (must be >=0755 and <=0775)
wireguird: done

What should I do here? This comes up when running ./package.sh on Linux Mint 20.3 Cinnamon.

I did a snap install go --classic to get over the "command not found" for go but the "control directory has bad permissions" error persists.

Not a big deal, the .deb installer works fine, but just figured I'd ask!
