A workaround by "dirtyhawk" from the linked thread:

chmod -R g+w /path/to/limesurvey

An even better solution would be to have a general path-check, which also checks paths for templates, uploads and the like...

EDIT: ...in the admin-panel, which might display problems on login of Super-Admins.

a 'chown apache:apache /path/to/limesurvey' make it work to me (the 'chmod -R g+w /path/to/limesurvey' didn't work for me)

xhiena, your solution does work, as does the chmod variant is most cases.

But the problem is that giving apache all-write access is pretty vulnerable for attacks. Thats why it's a workaround and not a solution.

Of course, if you system is not "very important", the quick-and-dirty solution is okay, but better is to give apache only the rights it needs to run the site.

from the forum http://www.limesurvey.org/en/forum/installation-a-update-issues/93955-error-in-comfort-update

this worked for me as well (this was someones suggestion and it worked)

BELOW IS THERE TEXT:

Hi!

i had exactly this same bug and I managed to avoid this by modifying file:

/var/www/limesurvey/application/libraries/admin/pclzip/pclzip.php file.

Line:

// Samples :
//define( 'PCLZIP_TEMPORARY_DIR', '/temp/' );
// define( 'PCLZIP_TEMPORARY_DIR', 'C:/Temp/' );
if (!defined('PCLZIP_TEMPORARY_DIR')) {
define( 'PCLZIP_TEMPORARY_DIR', '' );

I removed // and change tempory dir to /tmp where is 777 rights.

define( 'PCLZIP_TEMPORARY_DIR', '/tmp/' );

Reason for this was I wasn't able to find correct place where this zip should have 777 rights by default. No I managed update my limesurvey with comfort update. :woohoo:

This will be fixed in the next build by using the LS /temp dir.

Very nice! Is the /temp directory checked for writability though?

During LimeSurvey installation, yes.
