I have mirrored the Ubuntu archive repository (I must say it's rather huge). Then, I can apt-get install with no problem, but it prompts with following warning:
WARNING: The following packages cannot be authenticated!
xxxx, xxxx, ...
Install these packages without verification [y/N]?
Well, you can always install it.
But, I can't install from the Ubuntu software GUI. Which require trusted source.
So,
- How to force the GUI to install untrusted package?
- Should I configure GPG to receive some public keys? (I've already installed ubuntu-keyring, debian-keyring, but it still untrusted)
- Should I configure GPG to receive unknown keys from some specific keyservers, automatically?
Well the proxy server doesn't help for me. In China, the connection to America is rather slow, and I just can't wait tons of hour to just download something for the first time, this is why I mirror the Ubunto repo, because I can let the mirror downloading everything when I'm sleeping. And one day when I want to install something, it's just there, just in my local USB box, I hate waiting. – Xiè Jìléi – 2010-07-10T08:19:08.793
