Time Warp / Clock Problem - Ubuntu Alternate CD install over Ubuntu Server
I am having trouble installing Ubuntu Desktop Alternate CD on top of Ubuntu Server.
Here are the steps I've taken:
1. Downloaded i386 Alternate iso and burned it to CD-RW with Poweriso
2. Turned Server on, let Ubuntu Server boot up, logged in with credentials
3. Typed "sudo apt-cdrom add" (system asks for disc to be inserted)
4. Insert Disc and the following information comes up:
Found 2 packages, 0 source indexes, 0 translation indexes and 1 signature
Found label 'Ubuntu 9.04_Jaunty Jackalope_ - Release i386 (20090420)
This disc is called 'Ubuntu 9.04_Jaunty Jackalope_ - release -386 (20090420)
Copying package list...gpgv: signature made 20 Apr 2009
gpgv: key FBB75451 was created 32812922 seconds in the future
Time warp or clock problem
gpgv: can't check signature: timestamp conflict
E: Sub-process gpgv returned an error code (2)
W: Signature verification failed for: /cdrom/dists/jaunty/release.gpg
I then typed: sudo vi /etc/apt/sources.list - and it shows the CD says "main restricted."
Does anyone have a clue what is going on?
