This question about Configuration: More info required

The following critical dependencies are missing: ubuntu AWS problem

Hello,

I am trying to install and configure the Foswiki on the AWS ubuntu server. I followed pretty much the entire installation procedure from the webpage, and all went fine (at least I haven't see any obvious errors). However, when it comes to the configuring part, I am getting this error [1] at */bin/view. The other user reported a similar problem in this support list but for the Windows server, but the responses there didn't help my case.
I would appreciate it if anyone can give me some hint on what to look at for the solution. I am not that familiar with perl/foswiki.

For the additional info:
I ran the perl tool/dependencies and didn't observe any obvious problem [2] so I am not sure what I am missing in the installation/configuration part. Also, the output of perl -V is below [3].

I feel that there is some silly issue hidden somewhere that I am missing; any help is very much appreciated.

Thanks,

Nik

**** ERROR ****
The following critical dependencies are missing from your installation:
... Crypt::PasswdMD5: Can't locate Crypt/PasswdMD5.pm in @INC
... Error: Can't locate Error.pm in @INC
... File::Copy::Recursive: Can't locate File/Copy/Recursive.pm in @INC
... JSON: Can't locate JSON.pm in @INC


Please install these modules and then ensure all dependencies are installed by either:
- viewing the PerlDependencyReport in your local Foswki, or
- running the CLI shell script tools/dependencies from your server's command line.
You can get a complete list of Perl module dependencies by viewing SystemRequirements
on your local system or at http://foswiki.org/System/SystemRequirements.

Foswiki will not operate correctly unless the required dependencies are installed.

Your current library search path @INC contains:

/var/www/foswiki/lib
/etc/perl
/usr/local/lib/perl/5.18.2
/usr/local/share/perl/5.18.2

/usr/lib/perl/5.18
/usr/share/perl/5.18
/usr/local/lib/site_perl

You can adjust the search path by editing bin/LocalLib.cfg

From the errors reported when you run bin/view, it looks like the perl dependencies are not installed. On an Ubuntu system, you need to run the following:

     apt-get install libalgorithm-diff-perl libarchive-tar-perl libauthen-sasl-perl libcgi-pm-perl libcgi-session-perl libcrypt-passwdmd5-perl libdigest-sha-perl libemail-mime-perl libencode-perl liberror-perl libfile-copy-recursive-perl libhtml-parser-perl libhtml-tree-perl libio-socket-ip-perl libio-socket-ssl-perl libjson-perl liblocale-maketext-perl liblocale-maketext-lexicon-perl liblocale-msgfmt-perl libwww-perl liblwp-protocol-https-perl liburi-perl libversion-perl 

This is all detailed in the "Ubuntu and other Debian" section of SystemRequirements.

I'm not sure why perl tools/dependencies is not reporting anything. There is so much missing that it's failing somehow. Either that or the perl from the command line is running a different perl than the apache server.

One more question - do you know what version of ubuntu is installed in AWS? I've tried to recreate the issue you encountered, but have not succeeded.

-- GeorgeClark - 31 Mar 2017

Hi George,

Thank you for the feedback. I am looking at your responses now... Actually, all the dependencies above (apt-get install * ) were done successfully (see below). Maybe there indeed is some problemswith perl? I am looking into this, but is there a best way to fix this?

I use v14 ubuntu: Welcome to Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-107-generic x86_64)

At this point I have no idea. If the modules are all installed and available via the shell, somehow apache must be using a different perl. Did you make any changes to the bin/LocalLib.cfg file (copied from bin/LocalLib.cfg.txt?) That's all I can think of off hand that would possibly impact library loading on perl. Though that should also impact the shell execution of Foswiki as well.

All I can suggest is to check if apache is somehow using a different perl. Maybe someone else will jump in with other ideas.

-- GeorgeClark - 02 Apr 2017

No, I haven't made any changes in the LocalLib.cfg.txt. Thanks for your feedback, I will try to dig into this. If anyone has any suggestions, please let me know. Thanks!
