error installing perl module Net::SSH::Perl

Question

emphasized textWhile installing perl module "Net::SSH::Perl" using perl -MCPAN -e "install Net::SSH::Perl" is not showing any error only Result:PASS but using cpan -D Net::SSH::Perl showing not installed. What is the reason for not getting installed.

I tried to install Net::SSH::Perl on Ubuntu 20.04, perl 5.30 with cpanm Net::SSH::Perl but the installation of the dependency Crypt::Curve25519 failed (I am looking into it) — Håkon Hægland

You can just use cpan Net::SSH::Perl to install the module. — brian d foy

I was able to install the module after patching the dependent module Crypt::Curve25519 like this.

First create a patch Crypt-Curve25519-0.06-missing-version.patch:

diff --git a/lib/Crypt/Curve25519.pm b/lib/Crypt/Curve25519.pm
index 686b706..d9c2b3d 100644
--- a/lib/Crypt/Curve25519.pm
+++ b/lib/Crypt/Curve25519.pm
@@ -1,4 +1,5 @@
 package Crypt::Curve25519;
+our $VERSION = 0.06;
 #ABSTRACT: Generate shared secret using elliptic-curve Diffie-Hellman function

 use strict;

Then, run:

wget https://www.cpan.org/authors/id/S/SR/SREZIC/patches/Crypt-Curve25519-0.06-PR10-ANOTHERLINK.patch
git clone [email protected]:ajgb/crypt-curve25519.git
cd crypt-curve25519
git apply ../Crypt-Curve25519-0.06-missing-version.patch
git apply ../Crypt-Curve25519-0.06-PR10-ANOTHERLINK.patch
perl Makefile.PL
make  # No errors now
make test
make install
cpanm Net::SSH::Perl

I'm trying to build this for a Docker container that only connects to one specific machine. Is this module truly needed or is there a way to skip this dependency and have it still "work". If for example, the host I'm connecting to does not use curve25519 in any way.
