After updating repository info I recieve this errors:

W: GPG error: ftp://ftp.snt.utwente.nl unstable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F1D53D8C4F368D5D

Also, I want to install j2re from synaptic. But then I select 'sun-j2re.1.5' and click apply, synaptics says:

sun-j2re1.5:
Depends: sun-j2re1.5debian but it is not installable

what's wrong with it?

I read ubuntu FAQ about java, but really I don't like this solution. I want to be able to easy uninstall package I installed, but ubuntuguide's solution doesn't give me such privilegies.. :-?
How to get it working from installing .deb packages?

The entry in that guide is a little odd, not to mention that somebody besides Sun is distributing the JRE, which I suspect is a no-no. You just want to follow the directions here:

Under method 2. This will work under hoary.

That first "error" Isn't a problem, it's that the older repositories haven't been GPG signed yet. It's not going to be a fast transition, and as long as you have extra repositories, at least for a year or so, you will get that error. :D
