I have
I want to replace the audio in the mkv file with the audio from the ogg file. How can I do that on Ubuntu 11.10 with programs available from default repositories?
The resulting file may also have another format (e.g. avi), but I would prefer mkv. Btw. doesn't ffmpeg have an mkv muxer? My test with param -f mkv resulted in error Requested output format 'mkv' is not a suitable output format

Go to the “Audio” tab and next to Audio Track 1, click the plus button to add as many audio tracks as there are in your MKV video. Then, choose the track that you want to set as default and check “Edit this track” > tick “Default track” > keep it as “Yes”.
Matroska file format (mkv) is specified with -f matroskaoption. It should be supported by ffmpeg (version 0.7.3) in Ubuntu 11.10. Use ffmpeg -formats for a list of supported file formats.
To merge specific streams (audio or video) from several files use -i option for each input and -map input_index[:stream_index]. For example, the following command merges the first stream of the first input with the second input and keeps the codecs:
ffmpeg -i input.mkv -i input_audio.ogg -map 0:0 -map 1 \
-vcodec copy -acodec copy output.mkv
