comment mysqldump problems
What's the database name you're supplying? Is there anything spurious in the [client] or [mysqldump] sections of any of your my.cnf files? Special characters in your password?

comment problem removing mysql
When you see E:Sub-process /usr/bin/dpkg returned an error code (1), you need to scroll up. The actual error may have occurred many lines previous.

comment Amazon EC2 Ubuntu Server 14.04 apt doesn't work can't install
I don't think that's the "full" error. Scroll up for a previous, more specific message.

comment Is syncing a MySQL database with Dropbox this easy, and is it a backup solution?
What they are most likely achieving is a false sense of security. Yes, I suspect a backup is the intended outcome, but unless the server has very low traffic and Dropbox's algorithm is very aggressive, it's unlikely that the backups will be viable. Even then, the server, during startup from such a backup, is likely to need some time to recover from what it sees as evidence (in the files) of a crash occurring... best case.

comment Ubuntu virtual memory overcommit apparently hitting MySql performance
Where is /dev/sdb mounted? I don't see a memory issue here, but 100% disk saturation seems to be telling you something. Does the performance of MySQL improve after it has been running for a while?
