Thanks a lot for pointing out --show=debug flag, a very useful one.

My problem is solved now. Here is a description of what happened.

Following your advice on ssh versus local shell invocation
I tried the following commands:

1) logged into 'testdev' with ssh address@hidden
   and ran the same command as Fabric sent to the remote host:
   $ sudo -S -p 'sudo password:'  /bin/bash -l -c 'dpkg -i testpackage.deb'

   Worked fine.

2) Then from my local host I ran:
   $ ssh address@hidden "type -a sudo"
   Password:
   bash: line 0: type: sudo: not found


That was the problem and I remembered that when invoking
a command on a remote host through SSH only ~/.bashrc is executed.

So I checked both ~/.bash_profile and ~/.bashrc of 'testuser' and
they were different -  ~/.bash_profile set PATH to contain
system directory which in turn contained 'sudo' binary and at the 
same time ~/.bashrc file was empty.

So the problem was fixed by setting PATH in ~/.bashrc file.

Once again thanks for your suggestions.
Now I know more about Fabric and love it even more :)
