I have downloaded gnumeric-common_1.12.9-1_all.deb and in order to install it I used; "sudo dpkg -i gnumeric-common_1.12.9-1_all.deb". It seems that the application gets installed because I get the following output: "(Reading database ... 254589 files and directories currently installed.) Preparing to unpack gnumeric-common_1.12.9-1_all.deb ... Unpacking gnumeric-common (1.12.9-1) over (1.12.9-1) ... Setting up gnumeric-common (1.12.9-1) ...

However when I try to run gnumeric filename.gnumeric the response is The program 'gnumeric' is currently not installed. You can install it by typing: sudo apt install gnumeric.
I get errors when I run sudo apt-get update and sudo apt-get install gnumeric. That is the reason why I decided to download the .deb file. It seems that ubuntu 17.04 packages are not available any longer and the advice is to upgrade to 17.10. I cannot do that now. Is there another solution to install gnumeric without having to upgrade to 17.10?
I cannot install the application directly from ubuntu software by means of the ICON in the applications section. I get: Detailed errors from the package manager follow:
apt transaction returned result exit-failed
