I have Linux Mint and Ubuntu Studio and Solus installed on an SSD and when I use the Terminal in the first 2 OS, I use sudo to execute a command. But sudo does not work in Solus, so how would I install a program with the terminal? The Program I want to get is Kdenlive. and also KINO.

    Palladiniu Solus use eopkg package manager.
    To install kdenlive simply run:
    sudo eopkg it kdenlive or
    sudo eopkg install kdenlive. About kino I don't think it is in the repository. To search for a package run eopkg sr or eopkg search.

        algent I copied and pasted the commands you posted and my Machine throws up an error every time I tried it

            Palladiniu I copied and pasted the commands you posted and my Machine throws up an error every time I tried it

            Then there's something wrong with your setup. (1) sudo is a standard UNIX/Linux command, and (2) kdenlive is present in the Solus repository. Here's the result when I search for it:

            # eopkg sr kdenlive
kdenlive         - Video editing application, based on MLT Framework and KF5
kdenlive-dbginfo - Debug symbols for kdenlive

            This might be a good time to check to be sure your Solus installation is complete and up-to-date.

            EDIT: It would help others to help you if you'd post the errors that your machine "throws up" every time you try to use these common commands. They may provide the clues that will help someone to help you.

                        brent I have No Idea, I installed Solus the way I installed all my other Operating Systems. I have Multiple Hard Drives in this Computer, the Operating Systems sit on a 500 GB SSD, I have a 500 GB M2 drive and I have 4-2TB hard drives in the box All these OS would be sitting on that M2 but about 2 weeks ago, I lost that Little screw that holds it down.

                            I do not know what eopkg is. Is it something that should be showing if I open Applications and search all, I do not find anything named eopkg. I have no idea, where I can get the software Manager in my other 2 OS, I see no such thing in Solus.

                            Palladiniu What's an XFCE terminal? Something you installed outside repo? In that case all bets are off.
                            Install stuff from the native gnome-terminal.

                                I would also take @WetGeek 's advice:

                                sudo eopkg check
sudo eopkg up

                                you should always start troubleshooting, as he said, from a clean slate: updated system, no broken packages

                                Palladiniu sudo: eopkg: command not found

                                This is pretty unambiguous. It appears that eopkg is not present, further supporting my suspicion that your system is incomplete and not up-to-date. If I were in your situation, I'd probably reinstall Solus again, and then run an update, being careful to make sure that it ran to completion. Because eopkg is an inherent and important part of Solus and it's definitely what you need in order to install software packages.

                                    WetGeek (absence of this package, if true, will be about the weirdest thing I've seen in a long time🙂. I was wondering if it failed to locate eopkg, then I thought, "no how could that happen? " Can you have the packages and not the package manger? I believe you may be right.

                                      brent What's an XFCE terminal?

                                      XFCE is a fairly lightweight DE that I've used on several other distros. It provides its own terminal emulator, as do other DEs. I have no idea why anyone would want to install it on Solus, except maybe out of curiosity. As far as I know, it should work, but so does the terminal that Solus already provides.

                                      Another possibility is that he wasn't running on Solus at the time these commands failed. It would be natural for another distro to complain that it doesn't know about eopkg if that were the case.

                                            WetGeek likely even more variables...it's unambiguous that terminal output didn't know what eopkg was, agree.

                                            (I took MXLinux with XFCE for a week long test drive. Eh, ok).

                                              The EFCE Terminal was what was installed on Solus
