New to Linux; Downloaded for emulator OS

Hello I am VERY new to Linux when I started I bought a thumb drive and decided to Install Ubuntu 19.04 to a partition on my Internal Drive. I looked for some classic NES emulators and Playstation emulators. As looking for some emulators I found out that there is an apt already in the files of Ubuntu so I opened to terminal and ran the command to install PCSXR. Looking for some ROMS to download to play on my newly installed emulator the files were mostly .zip as a big time Windows fan I extracted them and looked for a Setup.exe application to run the install but can't seem to find them any files. I also tried to downloading some other emulators and adding some PPA but I got an error message reading

alexdavis1998@Alex-Davis:~$ sudo apt-add-repository ppa:gregory-hainaut/pcsx2.official.ppa

Is this because Ubuntu 19.04 was just released and isn't supported by alot of PPA's yet. I'm stuck and thinking of deleting the OS and going to an older version 18.04

Thanks for all the help

Try retroarch. add the ppa with:

sudo add-apt-repository ppa:libretro/stable && sudo apt-get update && sudo apt-get install retroarch*

for stable or

sudo add-apt-repository ppa:libretro/testing && sudo apt-get update && sudo apt-get install retroarch* 

for testing. After that install the cores for the emulator you want. (from )

As ppa's are unofficial, you have to depend on the maintainers, sometimes a single person. Some ppas will only provide packages for (the last) LTS, some only for the last version. As 19.04 is relatively new, it might take some days/weeks until the maintainers have packages ready.

There is a related issue on the github account (Ubuntu Cosmic repository does not have a release file).

With the author answering:

I don't plan to add it for multiples reasons

• I don't have any free time
• Some GCC workarounds must be backported to 1.4 branch (back to first point)
• 1.4 is rather outdated

There is another ppa available with latest dev version (check pcsx2.net for the link).

The issue is about 18.10, but I assume it is the same for 19.04.

You can use the daily builds ppa instead:

sudo add-apt-repository ppa:pcsx2-team/pcsx2-daily
sudo apt install pcsx2.snapshot 

I can recommend to use official packages - pcsxr and pcsx2.

So you remove the problematic PPAs with:

sudo add-apt-repository -r ppa:gregory-hainaut/pcsx2.official.ppa
sudo add-apt-repository -r ppa:sergio-br2/vbam-trunk

and install packages from universe repository with

sudo add-apt-repository universe
sudo apt install pcsxr pcsx2
