I am using Ubuntu 16.04 and Swift 5.2
Tried installing Vapor 3 using these sequence of command
git clone https://github.com/vapor/toolbox.git
cd toolbox
git checkout vapor3
swift build -c release --disable-sandbox
mv .build/release/vapor /usr/local/bin
on execution of
mv .build/release/vapor /usr/local/bin
Ubuntu says
mv: cannot stat ‘.build/release/vapor’: No such file or director
no vapor file or directory exists inside .build/release
