What happens when you lose ssh connect while doing a process?

I was shelled into my remote webserver from my laptop, and I lost my wireless connection while installing Mysql. Should I expect broken packages, or would it finish without me connected?

No, the process doesn't continue. It's aborted. But don't worried MySql and all Databases know what to do in this cases. This mean, the databases may continue in a consistent form: all tables, data, etc. are not lost.

If you're using an SSH terminal login (not a VNC session), then you could use screen(1) to maintain a logged-in instance on the remote system.
