SID-01331: "Error accessing TWiki.org: Incomplete headers" on VM

Status:	Answered	TWiki version:	5.1.0	Perl version:	From VM
Category:	CategoryError	Server OS:	CentOS	Last update:	14 years ago

I just downloaded the latest VM of Twiki (file name: TWiki-VM-5.1.0-1.zip). After going through the initial configuration when I click on "Extensions" and then "Find More Extensions" I get the following error message:

Error accessing TWiki.org: Incomplete headers This is most likely because the LWP CPAN module isn't installed.

It sounds like there are files missing from the VM installation. Is there a way to add the correct CPAN files for the CentOS used for this VM?

Discussion and Answer

It looks like CPAN:LWP needs to be installed. See HowToInstallCpanModules. Please report back how you solved it.

It is working for me now on the VM. Here's the process I followed:

1. Tried to update and install the required CPAN modules based on this link: http://twiki.org/cgi-bin/view/TWiki/HowToInstallCpanModules

# perl -MCPAN -e shell cpan> install Bundle::CPAN install CGI::Session install Error install FreezeThaw install GD install HTML::Tree install Time-modules cpan> reload cpan exit

Unfortunately this didn't work and was getting the same error message.

2. Before I saw PeterThoeny's message I found this page: https://bugs.launchpad.net/turnkeylinux/+bug/695873

Which indicated that the libwww-perl module was missing.

In CentOS on the VM we ran the following command:

yum install perl-libwww-perl.noarch

Which seemed to be the closet match to the missing libwww-perl module.

Once this was installed the Extensions feature is working and I can see data now.

Can this be added to the VM going forward so it doesn't need to be done manually?

Thanks Matthew, I'll add it to the next VM release.
