Okay, if it asks for password then it sounds like the update-sudoers -command isn't executed correctly @ postinst script during installation. Thanks for testing, I will look into it later :)

Managed to use "convertplastic" utility calling it via "/sbin/convertplastic". I've modified a string in your script:

"sudo conplast "$@"" in "echo "/sbin/conplast $@" | root". Don't know if it helps, I know about nothing of Linux.

It asks me for the password, in order to use the sudo command. That's just for convertplastic; conplast works well if called with "/sbin/conplast", but of course it doesn't gain powers for using mkdir in /opt.

Okay.. will the script run (as user) if you type: /sbin/convertplastic

Hi again Ricky,

it seems that on a fresh N900 the problem still exists, so it's not my phone's fault. Let me know if you need further help.

"chown user users /sbin/conplast" doesn't work, instead I used "chown user /sbin/conplast".

However none of your suggestions worked, convertplastic is still not foundable with user powers. I'm trying to install your app on a freshly flashed N900 (I've more than 1 N900), I'll tell you if the "problem" is related to my phone soon.

I get exactly same output on my device.

Could you kindly try if this helps (type as root): chmod 0775 /sbin/conplast

and

chmod 0775 /sbin/convertplastic

And if that doesn't help, try to this for both files: chown user users /sbin/conplast

I get exactly same output on my device.

Mmhh, I agree that's pretty weird. The output of my "convertplastic", as already said, is simply

-sh: convertiplastic:not found

Output of "ls -l /sbin/conplast":

-rwxrwxr-x 1 root root 1159 Aug 31 12:41 /sbin/conplast

Output of "ls -l /sbin/convertplastic":

-rwxrwxr-x 1 root root 101 Aug 31 12:41 /sbin/convertplastic

That's weird. I tested several times on my unit that script launches fine with regular user priviledges.

Can you provide output of: ls -l /sbin/conplast ls -l /sbin/convertplastic

Thanks.

Now convertplastic works if run as root, but it still doesn't work if used with user powers.

However, if used as root it works very well, tested with humanity theme.

You should mention this nice utility in the description ;)
