This question about Configuration: More info required

The following critical dependencies are missing: ubuntu AWS problem


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.

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

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

Your current library search path @INC contains:


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)

Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'perl-modules' instead of 'libarchive-tar-perl' Note, selecting 'perl-modules' instead of 'liblocale-maketext-perl' libalgorithm-diff-perl is already the newest version. libauthen-sasl-perl is already the newest version. libcrypt-passwdmd5-perl is already the newest version. liberror-perl is already the newest version. libfile-copy-recursive-perl is already the newest version. libhtml-parser-perl is already the newest version. libhtml-tree-perl is already the newest version. libio-socket-ssl-perl is already the newest version. libjson-perl is already the newest version. liburi-perl is already the newest version. libwww-perl is already the newest version. libcgi-pm-perl is already the newest version. libcgi-session-perl is already the newest version. libdigest-sha-perl is already the newest version. libemail-mime-perl is already the newest version. libencode-perl is already the newest version. libio-socket-ip-perl is already the newest version. liblocale-maketext-lexicon-perl is already the newest version. liblocale-msgfmt-perl is already the newest version. libversion-perl is already the newest version. liblwp-protocol-https-perl is already the newest version. perl-modules is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 48 not upgraded.

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!
