Installing .deb file to a different location on Linux Mint
 

I've been trying to install a .deb file from my travel drive to another location on my travel drive using this command:

For some reason this is not working, so how could I fix this?

I have never done this before, but a look at the man page tells the --root=/foo command makes /foo the root directory for the entire installation process.

So 2 things could be happening: If the install package is located in /foo/blah.deb, you should install blah.deb, not /foo/blah.deb.

Secondly, dpkg expects a complete directory tree with directories like /usr /bin /lib /etc and so on. Once you set root to /foo, there must be a directory structure below /foo, thus /foo/usr, /foo/var. And that might be the hardest, I don't know if dpkg creates them.

Besides, any package running expects a correctly set up /tmp, /var, /bin, /etc and whatnot. If you don't have them, the program doesn't run.

I'm not familiar with the --root option either. I tried it specifying an empty directory but it didn't work in my case (i.e. the package got installed on my root file system instead of the directory I specified).

That said, I think the OP's problem is that the path to the package contains a space and dpkg doesn't seem to like it, even if quotes are being used. I would simply try to cd into the directory containing the package and specify the root install directory scaping the space with a back slash.

edit: In addition, dpkg probably expects a file system structure in the target directory as jlinkels said.
