Halo,
I can't find the packages for myanmar-fonts-switcher and zawgyi-keyboard for ubuntu 18.10. I already tried this guide. But getting "Unable to locate package" error. I also searched there for related ppas. But actually I am a bit confusing about ppas . We can't install ppas from older versions ? If there is a way please kindly guide me how to . Any help and explanation is highly appericiated . Thanks
