“Missing shasum binary”

[prembhaskal]

can you please the OS information where the script is run?

To unblock users can install shasum (with the Linux package manager that their distribution uses) and then run the script.

example: dnf install perl-Digest-SHA

can you please the OS information where the script is run?

centos 7.5

This version of CentOS doesn't include shasum, which the install script currently requires. However, since shasum isn’t strictly necessary (as sha256sum and sha1sum can serve the same purpose), I opened a PR to make the script compatible with all three. The PR hasn’t been merged yet.
