after devel-su (to become root, as you apparently did)
issue command develsh for higher priviledges. That should do it!

because vfat/fat/fat32/etc do not support owner, group or acl in general

Nop

Code:
~ $ devel-su
password:
~ # develsh
~ # cd /home/user/MyDocs/
~ # chown -R root:root ./data
chown ./data... :operation not permitted

Remember to always use devel-su -s /bin/develsh when you want to go root - otherwise you often actually lose capabilities from before you switched to root.

Also, as was already said, the MyDocs folder is on a FAT32 partition, which doesn't support users/groups/permissions at all, so you need to move your files to somewhere else (e.g. /home/user) instead. However, I haven't been able to run dpkg -b successfully anyway, so if that's what you're trying to do it probably isn't going to work.

thanks it works but as you said i cant deb thanks anyway, so the only way to deb is through a pc?

Yeah. Your best bet is to set up the Harmattan Platform SDK (Scratchbox) on a Debian/Ubuntu install - if you use something else, make a virtual machine. You can then put together a source package and use dpkg-buildpackage to compile it into a .deb. However, that's a lot more complicated of course - I don't think there's a good solution for making "quick and dirty" .debs.

(On the other hand, there's a lot of half-baked .debs for Maemo - it's probably a good thing if people start using the more official tools in order to make high quality .debs)
