Please somebody help me to resolve this.

Linux executables do not have the .exe extension. Which version of Ubuntu are you using? Have you still got the installation DVD?

@sycamorex
Sorry it wasn't exe file but looks like that and properties showed executable .I am using ubuntu 10.04.Now what to do ?

Thanks.

Yes, the file had executable permissions. I was just pointing out that linux does not use the .exe file extension. It's a windows thing.
Please check the links I posted above. They seem to have solutions to your problem.

According to your link when i tried ,i got the following error.
sudo apt-get install dpkg --reinstall

This post appears to help, according to the OP on that forum thread. (same type of problem)

What about the second link, post #6?

that's the same, as my link (based on your link, lol) .. but with a "it works" comment

Did not notice your comment when writing mine

I tried the this link too.But at the last command i got error as:

Perhaps, some ubuntu users will be able to crack this one as I have no other suggestions than
installing dpkg from source. I'm sure there's a simpler solution, but if the worst comes to
the worst, you can always grab dpkg sources and compile it:

The easy way is to download a dpkg for your Ubuntu version.
http://packages.ubuntu.com/hardy/dpkg

ar dpkg_<version>.deb : will unpack to : data.tar.gz
tar xvf data.tar.gz : will unpack the executable /usr/bin/dpkg

... Then : sudo cp dpkg /usr/bin/
...

I have now /usr/bin/dpkg execable file.but still
sudo dpkg --configure -a
give the error like
dpkg: failed to open package info file `/usr/local/var/lib/dpkg/status' for reading: No such file or directory


Thanks

Normally the status file should be in /var/lib/dpkg/status, at least it is on ubuntu 10.10. What is the output of
ls -l /var/lib/dpkg/

If 'status' is in it you could create a link to it like
ln -s /var/lib/dpkg/status /usr/local/var/lib/dpkg/status

If you keep having more problems related to missing files in /usr/local/lib/dpkg/ then you could try to relink the whole directory, i.e. if the config files are available in the default directory (/var/lib/dpkg/).
