Ubuntu 16.4 don't run command setup-seafile-mysql.sh

If i try to run command “setup-seafile-mysql.sh” on Ubuntu 16.4 and i have this error: -bash: setup-seafile-mysql.sh: command not found
Is anyone aware of this problem?

You have to run

./setup-seafile-mysql.sh

I tried but did not succeed…
-bash: ./setup-seafile-mysql.sh: No such file or directory

Are you in the right folder? What’s the output of

ls -a

?
