error when updating module

Question

I'm trying to update my colorbox module and I keep getting the error:

Update failed! See the log below for more information. Your site is still in maintenance mode.

and below it says:

colorbox

Error installing / updating File Transfer failed, reason: Cannot remove directory /home/content/02/12910502/html/sites/all/modules/colorbox/..

Next steps Your modules have been downloaded and updated. Run database updates

why do I get this error and how can I get this fixed?

EDIT1
I'm using GoDaddy shared hosting. All permissions for files & directories in ftp are set to 755 (owner 12910502) within colorbox/ but I still get this error... - I've never had a problem on other sites I'm working with, weird.
This is drupal core 7.15 - may that be the reason?

EDIT2
How abut if I just replace the directory onthe ftp with the latest version and then run update.php, should this work too?

Answer 1

Sounds like a permission issue.

If you're using ubuntu, make sure the user owner for your modules folder is www-data and 755 permission.

Also, don't forget to run update.php by going to www.yourwebsite.com/update.php after you update drupal core OR any module.

Answer 2

I ended up upgrading the modules as I suggested in EDIT2 above. Worked fine except ctools, that module is still pending...
