Does debian have a utility I can run to check and repair disk permissions?
On a mac under applications and utilities and under disk repair utility
there's a function for repair disk permissions which can check permissions
against a known default set and repair if necessary. It could be the
problems I'm having with dpkg may be because some permissions somewhere
aren't set right.

In most GUI File-managers you check and change permissions by right
clicking an item and clicking properties (or something similar). You
may also want to take a look at the "chmod" command". It's probably
worth noting that generally dpkg is run as root - whenever I see
instructions on using it,, the instructions always seem to follow the
format
su
dpkg ....

If all you want to do is ensure that all the files have a specific set
of permissions, you can either use 'chmod -R <perms>' on a directory or
use 'find' to select the files and then use chmod on each of them.
Something like:

$ find <dir> <specs> -print0|xargs -0 chmod <perms>

You can also use 'find' to report existing permissions. Look into the
-printf option of find, particularly the %M and %m directives.

Look into the man pages of find, chmod and xargs for details.

Hi Jude,

What is the output of the following command: lsof /usr/bin/dpkg

Queries from a lurker:

When running the above command as "user", I get:

lsof: WARNING: can't stat() xfs file system /dev/.static/dev
Output information may be incomplete.

Should the command be run as "root"; and if so, what might get broken ?
