UAE is the best Amiga emulator we have. Unfortunately the application in the Karmic repos segfaults and is badly maintained. I had to download the source and compile. Like cooking a meal. Works fine, except the sound isn’t exactly what it should be. If you want to test it. Here is the link to the deb compiled against Alsa. I might try this exercise again when I have the time, adding the < –with-oss flag> for the OSS open-sound server. Enjoy.
