How to get gpg2 installed on cygwin?

Trying to install gpg2 on win10. Followed bottom answer on this thread; how to install gpg on cygwin? currently it's missing

but got a problem when trying to soft linking them;

I have "the right" version when checking the new download;

$ /c/Program\ Files\ \(x86\)/GnuPG/bin/gpg.exe --version
gpg (GnuPG) 2.1.21
libgcrypt 1.7.6

And the old version is;

$ gpg --version

Having liked both;

$ ln -s /c/Program\ Files\ \(x86\)/GnuPG/bin/gpg.exe /usr/bin/gpg2
ln: failed to create symbolic link '/usr/bin/gpg2': File exists
$ ln -s /c/Program\ Files\ \(x64\)/GnuPG/bin/gpg-agent.exe /usr/bin/gpg-agent
ln: failed to create symbolic link '/usr/bin/gpg-agent': File exists

I don't get why I get this message;

$ gpg2
C:/msys64/usr/bin/gpg2: error while loading shared libraries: ?: cannot open
shared object file: No such file or directory

I am doing this because of;

$ \curl -sSL | bash -s stable
ERROR: Could not find GNU compatible version of 'tar' command, make sure it's available first before continuing installation.

If there is any other way around this to get RVM installed, I'll be happy to know

There is no need to install gpg2 using the complicated instructions in the link you have provided.

The gpg2 package is available through the normal Cygwin installer. If you install it using this it will be correctly configured.

• Run the install program

• Continue until you get to the "Select Packages" screen

• Set the "View" to "Full"

• Set "Search" to "gnupg2"

• Click the first "Skip" (it will change to the version number 2.1.21-1)

• Click "Next" to install

As reported by David, GNU Privacy Guard version 2 is available on Cygwin

as last version of 1

The two versions coexist in parallel.
