I can't install Perlbrew using the easy script: curl -L http://install.perlbrew.pl | bash

I did it before, easily, but now, in a brand new CentOS 6.5, I get a 400 Bad Request.

This is the output:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                             Dload  Upload   Total   Spent    Left  Speed
113   226  113   226    0     0    187      0  0:00:01  0:00:01 --:--:--   187
bash: line 1: syntax error near unexpected token `newline'
bash: line 1: `<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">'

And this is the response if I do the curl part (without passing it to bash)

curl -L http://install.perlbrew.pl

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html>
  <head>
    <title>400 Bad Request</title>
  </head>
  <body>
    <h1>Bad Request</h1>
    <p>Your browser sent a request that this server could not understand.<br />
    </p>
  </body>
</html>

This is my Curl version: curl -V

curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.14.0.0 zlib/1.2.3 libidn/1.18 libssh2/1.4.2 Protocols: tftp ftp telnet dict ldap ldaps http file https ftps scp sftp

Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz

Usual compilers are also installed with yum groupinstall 'Development Tools'

What can be failing? It is really strange...

The http://install.perlbrew.pl link actually points to https://raw.githubusercontent.com/gugod/App-perlbrew/master/perlbrew-install, which is a bash script. I believe that the curl command in this script is the one having the problem.

Try this: Save the perlbrew-install bash script to your machine edit the curl line:

PERLBREWDOWNLOAD="curl -f -sS -Lo $LOCALINSTALLER $PERLBREWURL"

by adding the -k option to disable cert validation (See curl insecure option). Comment out the surrounding if/else statements and then run the script from your command line.

Alternatively, you could try installing wget and do the suggested command from the perlbrew.pl site:

wget -O - http://install.perlbrew.pl | bash
