I am beginner 🙁 Please tell me how can i install .deb packages in Solus?

You can't. We aren't a Debian-based distro, nor do we use dpkg. Solus has its own package format called eopkg.

Edit: If you can tell us what you are trying to install we might either already have it, have a good alternative for it, or be able to help you install it.

    Energy40 you have to create a .desktop file. You can use mozo on MATE or menulibre on Budgie/Gnome for that.

        Even easier to use:
        From this post on the XnView forum, there is a link to the latest version of XnViewMP 0.93 in appimage format (direct link), XnViewMP which contains XnConvert.
        So it's very easy, since it's just a matter of making the appimage executable via the file properties. I tested it and it works flawlessly, same as my installed XnViewMP.
        To access the XnConvert function, select one or more images and then choose "batch conversion".

        I get the below error when downloading the debian_bridge. Appreciate any guidance

        Caused by:

          Linuxlover Do you have the development packages installed? If not, you'll need to install them with sudo eopkg install -c system.devel in order to compile programs.

            Hello dear Solus users ,
