As I continue to configure my Zorin Core VM, the next step was to be installing Vivaldi and configuring that. However, I download the .DEB file from the Vivaldi web site, and Zorin's Linux software installer wants nothing to do with it. Says "Failed to install file. Not supported." I tried with a different .DEB file, and the same thing happened.

This is an apparent change since the last time I worked with this OS, because at that time I had no problem installing Vivaldi this way.

Does anyone know what's up with that? Zorin's an Ubuntu offshoot, and uses apt in the terminal to install packages. Why wouldn't it install a .DEB file?

    WetGeek have you tried installing from the CLI? You'll have to be in the same directory so cd Downloads or wherever it lives and a `sudo apt install "vivaldi-stable-190.deb" or whatever file name should do the trick.

    Not sure why the GUI software isn't working though.

        Yes! Vivaldi is now in my Internet sub-menu. I haven't tried it yet, but I'm optimistic.

        Although I cd'd to the folder where it's located, I couldn't get anywhere with just the .DEB package name. I needed to prefix the current directory name to it, i.e., /mnt/Downloads/Linux. Thanks for your help.

            When I was testing Zorin Core for the railroad last fall, I installed a bunch of browsers (Edge, Chrome and a few others, as I recall) from .deb files, just double-clicking the .deb file in the /download file. If that is not working for you, something isn't right. In the case of Vivaldi, once it installs, you might get a persistent message asking for your administrator password each time you open it. I did with Edge. This is known Ubuntu behavior that requires you to register the certificate. That can get complicated and probably isn't worth fixing for a "look and see" VM instance.

              I think I just right clicked the deb and it had an install option.

                WetGeek I haven't tried it yet, but I'm optimistic.

                I've tried it now. Opened Vivaldi, added LastPass to it, fetched my Vivaldi password, did a sync, got 54 icons on my start page, and sorted them into named tab stacks. Now it's just like using Vivaldi on my laptop.

                It should have occurred to me that I could use apt to load that .DEB file, but I'd never done that before. Only ever used apt to install packages from the repository.

                  riffer I think I just right clicked the deb and it had an install option.

                  That's what I remember from the first time I worked with Zorin, I think it was in August. But this time something was different. It's possible it related to some changes I made, I suppose.

                  I'd created the VM and installed Core. Then I used the same VM. but changed the .ISO file to install Lite. After I found out that I could create virtual workspaces for Core, and I was done with Lite, I changed the VM back to the Core .ISO and installed that. And that's what I'm working with now.

                  I don't know whether or how all this might have mattered, but I guess anything's possible.

                    Nope,, nothing like that, fortunately. Everything's working as it should.

                      64bin in a 32 system?

                      other option maybe the gdebi app. it should be in the zorn os software center. it is basically a gui for the apt install command. once you download the app in zorin , open the file manager, right click on the file, chose open with and select gdebi and follow the prompts. this should work for all ubuntu based distros. good luck.
