SID-02042: Installation fails - folder /pub/... cannot be created

Status:	Answered	TWiki version:	6.0.1	Perl version:	v5.18.2 - built for x86_64-linux-gnu-thread-multi
Category:	LdapContribAdminPlugin	Server OS:	Ubuntu 14.04.2 LTS	Last update:	10 years ago

I tried to install it into a new local installation of v6.0.1 via configure and it fails with the following error message. From my point of view the problem is the path starting with / which is the root in linux systems. It should be relative like the path before. Do you need any additional details?

Install pub/TWiki/LdapContribAdminPlugin/gfx/led-cup-yellow.gif, permissions 0644
Install pub/TWiki/LdapContribAdminPlugin/gfx/led-cup-green.gif, permissions 0644
Install /pub/TWiki/LdapContribAdminPlugin/LdapContribAdminPlugin.css, permissions 0644

Error: Installer returned errors:

Discussion and Answer

No additional details needed: The installer is broken for this plugin. As you can see the "bad" paths are also visible at the plugin's page Plugins/LdapContribAdminPlugin.

So, while I can file a bug report and I can fix it in SVN, we need to figure out how to get the fix through to you... If you've been installing directly from twiki.org, I need to re-build the .tgz and .zip archives (both contain the error) and upload it. If you already have a local .tgz or .zip file, you can patch it yourself: Remove the leading slash from the paths in the file LdapContribAdminPlugin_installer, in the root directory of the archive.

Stay tuned, and thanks for reporting!

Addendum: I think I've got it fixed, new plugin available at Plugins/LdapContribAdminPlugin. Please give it a try!
