Time Warp / Clock Problem - Ubuntu Alternate CD install over Ubuntu Server

Hey All,

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:

Mounting CD-ROM
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?

Not 100% sure, but it sounds to me like you need to update the system date. Try running the command:
If that tosses back a funky time way off from reality,
This Site can explain a bit how to change the system date.

Good luck

Heh, yeah I would say thats probably the issue.

System had December 17th, 2003, LOL

I'll keep you posted on whether or not that fixes the issue
