i am stuck-up and will appreciate any help

Here again, I read all I could find in this forum, and tried to do the command line to rebuild the repository, and still I cannot install or update the applications on my N800.

The Application manager log file shows:

hildon-application-manager 2.1.16

I think that the problem comes from line:
dpkg: failed to open package info file `/var/lib/dpkg/available' for reading: No such file or directory
E: Sub-process /usr/bin/dpkg returned an error code (2)

Any idea on how can I fix this problem?

Running diablo from mmc2 (internal SD)

Thanks

Try:

sudo apt-get -f install

and (so I just read, so YMMV):

sudo dpkg --configure -a

I'm not sure what the available file should contain, perhaps an "apt-get update" would refresh it if it's supposed to contain available/installable packages?

thanks.
i tried and got this:

~ $ sudo apt-get -f install
Reading package lists... Done
Building dependency tree... Done

... and i am still stuck-up :-(

Try this:

touch /var/lib/dpkg/available

then:
apt-get update
or:
apt-get -f install
(basically something to fill that file with whatever it should contain)

Thanks lardman, it fixed the problem.

I think that the problem was a corrupted file

glad you've got it sorted out
