While trying to install suse 11.1 I get “cd:/ Invalid signature Installation aborted”.
I tried DVD and Network (CD) installation, same result.
My first attempt at downloading only downloaded 1.5 out of 4.3BG’s. It acted like it completed with no errors. I’m trying again.
Did your download get the whole file?
The dvd image is OK, I verified the checksum.
I can boot the system using the installation dvd, set the language etc. but after starting install I get the error message …invalid signature…
I’ve got a gigabyte mainboard and intel dual-core cpu (and no idea where the problem comes from, 10.3 and 11.0 works fine)
I have the same problem, but a slightly different abort message:
cd:**/content ** : invalid signature. installation aborted.
The downloaded iso has been checked against the md5sum, burned as iso image. Starting from DVD went normally, the menu allowed checking the dvd (successfully), at the end the “invalid signature” message appeared.
The beta5,KDE4 installation two weeks ago showed nothing extraordinary, went smoothly and lead to a working system.
What’s wrong?
I have had the same problem on my laptop and got the error message “cd:/content invalid signature”. I have tested it with USB-DVD and network install, both the same. I wondered that the problem also exists in Virtual Box with Windows as the Host system, but not on my Desktop system.
So I did some research, why the installation fails. It was successful, it’s quite easy to solve the problem.
I noticed that the system date of my laptop was very far in the past. I corrected the system date and time in the system bios and ran setup again. And now, it works :):)
Nice insight, bugmenot101
This is a good example of how error messages can be unfriendly to the casual user. I’d be hard-pressed to associate <invalid signature> to <invalid date/time signature>.
Thankfully some warnings at boot have suggestions on the fix. This eases the pain a little.
That was exactly the solution !
Thanks.
with the right systemtime it works… thank you
Sounds like this is my problem. I just reformatted and as i look at my clock, it thinks the year is 2002. I reset the clock in Windows. I wonder, do I have to go into BIOS and change it there? or did Windows change everything i need… we shall see.
… same Problem and solution here. Thanks for the good work!

Unfortunatelly this did not apply to my computer. The date is set to present time and still I get the same error. The computer I am trying to install openSuse on is a 8 year old computer with a mix of old parts in it. Maybe the very old network card is not supported?
thank you all
hopefully this will fix my problem tooo:O
Same problem … same fix. Interesting how date is related to the DVD signatures. one full day after checking all the hardware.
Thanks for the post !
im so happyyyyyyyyyy work thankssssssssss
Thanks a lot!
same problem, same solution. Thanks.
Annoying that the date reset is in the Wind>:(ze part (i.e. performing an update on an old dual boot) NOT the BIOS (which was OK).
Wow! would have taken years for me to notice this one. 
How do you change the BIOS system clock??? I am running into the same problem as well:(
