Question: I'm having some troubles with installing extensions with magento connect. When I start installing the extension the outline terminal writes something like this:

> 
> Checking dependencies of packages Installing package community/OrganicInternet\_SimpleConfigurableProducts 0.7.4
> 
> 
> CONNECT ERROR: Failed to open file
>  /var/www/magento/downloader/.cache/community/OrganicInternet\_SimpleConfigurableProducts-0.7.4/app/code/community/OrganicInternet/SimpleConfigurableProducts/Catalog/Model/Product/Type/Configurabl
> 
> 
> 

I checked the path and I found the requested file. As you can see the permissions should be fine ;-)

> 
> drwxrwxrwx 2 www-data www-data 4.0K Nov 3 11:10 Configurabl
> 
> 
> 

I have no idea what to do. I'm using PHP 5.5.4-1 - so that should be fine.

Do you have any idea what to do?

Answer: 
The error, in this case, comes from a php security mod that checks files on upload. There seems to be some non-ascii characters in one of the extracted files from the package and as soon as it encounters them it halts processing the file, hence the "Configurabl" is cut short.

What you need to do to get past this error is either adjust the settings of your uploader security mod, but most likely you don't have access to that. The other option is to download the package some other way (in this case it is available on Github at <https://github.com/organicinternet/magento-configurable-simple>), extract it and upload the files via FTP.
simply change the file permissions. index.php file to give 644
