My package repositories have been up for years and it is high time I said something.
DON'T USE THEM. Seriously. I use these repositories for development versions of packages I am working on, or backports for personal use, and they are quite often poorly maintained. They have been known to cause loss of data, loss of hair, erectile dysfunction, gout, hypertension, in-grown toe nails, and premature senility.
If for whatever reason you choose to ignore the above warnings, or on the off-chance I have specifically pointed you at these repositories, you can enable them by placing the following in your sources.list
