Hi @Ahmed_Elgamala ,

I do not think there is a different download source. I just tried to download the image and had no problems or corruption issues. 
How did you determine the image is corrupted?

i was trying to mount it after failed installation, but i think it's not available because image is encrypted, anyway the boot issue solved after i disable the secure boot option on bios setting

Hi,

I downloaded the Remote Exam ISO, checked that it has the correct md5sum of 0dd72ac558fc1afbf0c0e1fa4b366f10, put it on a USB drive and booted my desktop PC from it.

That all worked fine.

However, I don't get a network connection. The only options presented to me when opening the Network settings in the menu is to setup a VPN connection and a Network Proxy, but no settings for the wired network connection.

I suspect that it is due to the 2.5G NIC that I have on my Gigabyte Mainboard. It is working fine with Fedora 35 and using this driver:

$ lspci -k -s 04:00.0
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
DeviceName: RTL8111E Giga LAN
Subsystem: Gigabyte Technology Co., Ltd Device e000
Kernel driver in use: r8169
Kernel modules: r8169

Could someone check/verify if this driver is included in the Remote Exam ISO image, please ?

Is there any chance you could provide an updated image that includes this driver by Wednesday COB ? I have my exam Scheduled for Thursday....

As I have scheduled the next Exam I tried again and downloaded the latest ISO today (v20220712, md5sum 478157b7675223468d83253a241a1fd5).

That still doesn't seem to have the required driver included.

Any chance to have a new ISO published that contains this driver, before November 1st ?

"Any chance to have a new ISO published that contains this driver, before November 1st ?"

The current ISO was released recently and I do not PERSONALLY think there will be a new release soon.

On the other hand, your issue is easy to be solved just by using a simple USB to Ethernet adapter. 

Something similar to this:
https://www.amazon.com/ethernet-Adapter-Supporting-Ethernet-Network/dp/B084MCVVP9/ref=sr_1_9?crid=2W...

100Mbps version is more likely to be compatible and is fine for the exam. The price is under 10 USD. I had even seen some for 5 USD only.

I hope this helps

Yes, I was thinking about a USB <-> ETH Adapter as well already.

Or, alternatively, use an old(er) PC for the exam, which I already did before.

But obviously I would like the driver to be added, so I thought it might be worth to ask, as my last Exam is some months ago now.

Hi again,

okay, that ISO image doesn't seem to like me.

I just tried it on my MacBook Pro (End 2012, so pretty old I must admit), but that only gives errors during boot:

The ISO image will not work on Mac laptops. Only on RHEL/Windows OS is supported.

No no @arbhati, Intel Macbooks in general (not all) can really be used for the exam. But it may be challenging. 
Macs are very familiar to me and I should have answers to your questions. I do not want to be long, so ask me, if you have a particular issue and questions.
