sudo apt-get install gdebi-bodhi-launcher didn't work for me .
To avoid using the terminal every time, I have added a context menu entry in the file manager. For such purposes I usually find easier to install Thunar file manager. I have created a custom action called "Install deb" with the command:
terminology -e 'sudo dpkg -i "%f"'
Maybe gdebi could be preferred instead of dpkg, as it takes care of dependencies.
"%f" instead of just %f" in case some folder in path has a name with spaces. Appearance conditions: File pattern: *.deb, check "other files".
But that can also be added to pcmanfm: create a folder `~/.local/share/file-manager/actions`, then run in terminal:
and add this:
Name[en]=Install deb files
Name[en_US]=Install deb files
Name[C]=Install deb files
ToolbarLabel[en_US]=Install deb files
ToolbarLabel[en]=Install deb files
ToolbarLabel[C]=Install deb files
Exec=terminology -e 'sudo dpkg -i "%f"'
save the file, close it, log out and back in.
This should also work for Nautilus.
