yum not accessing repository when running F12-on-XO1

[Mikus Grinbergs]

Running on XO-1 with build soas-2-beta (booted from USB stick).

For several days now, 'yum' is timing  out with the message: "Error: 
Cannot retrieve repository metadata (repmod.xml) for repository: 
fedora. Please verify its path and try again."

Is the Fedora-12 repository having serious downtime problems, or is 
this something wrong with yum ?  [I experience no problem with 'yum' 
accessing the Fedora-11 repository when running F11-on-XO1 builds.]

Generally there's no issues with the Fedora 12 repos at the moment. Is
it trying to connect to the same mirror each time. It could be issues
with a particular mirror.

Fedora 10 unable to boot after updating XO-1 to 8.2.0

[Todd Robinson]

As some of you may know, we (On-Disk.com) do the Fedora 10 SD cards 
which are currently available for the XO-1, but which we will need to 
discontinue.

Currently the Fedora 10 SD cards no longer work after updating to 8.2.0 
(OpenFirmware CL1 Q2E41 Q2E).  When inserting the SD card it acts as if 
it's not inserted, except that it also doesn't attempt to boot Sugar. I 
suspect the olpc.fth is used a bit differently with the newer firmware 
version.

For informational purposes, the Fedora 10 SD cards work fine under older 
XO-1 firmware. The XOs also boot Xtra Ordinary fine after updating to 
8.2.0 but do not work with older firmware versions. (see: 
http://on-disk.com/product_info.php/products_id/881 - should be an 
article tomorrow at OLPC News).

I would love to be able to offer a Fedora 11 option, but from tracking 
this list there doesn't seem to be a version ready for public 
consumption (please correct me if I'm wrong). So this gives me three 
choices:
1. discontinue offering Fedora 10 on SD cards for the XO-1 and rely upon 
non-fedora XO options such as Xtra Ordinary and DebXO which run fine 
with the newer 8.2.0 os/firmware.
2. Continue to offer it, but warn that it must be used with older 
Firmware versions. (I would actually rather just discontinue it)
3. Find a fix to allow F10 to boot on the newer os/firmware.

Any advice or work-arounds anyone may have would be very much 
appreciated. I'll append the Fedora 10 /boot/olpc.fth in case it's helpful.


Thank you,
Todd

Fedora 10 unable to boot after updating XO-1 to 8.2.0

... you mean at this point that OpenFirmware doesn't read the
/boot/olpc.fth on your SD card, right?  You've tried changing it to emit
test characters or something?

I've reviewed your script.  The first line does not contain the key text
that DebXO uses:

	\ OLPC boot script

The second last line uses unfreeze instead of dcon-unfreeze.

There's some strange thing done to change the loading of the initrd,
using constants that aren't defined, so I don't know what that code you
have is trying to do.

However, I've checked, and the code between the [if] and [then] does not
trigger on Q2E41b.

My guess is that you haven't tracked the changes in OpenFirmware
correctly, or that the wrong first line text is used, or the unfreeze
should be dcon-unfreeze.

Lastly, check the line containing "root=UUID=4C67-D0F1", as it appears
to have wrapped in your e-mail.
