Karmic UNR CD size too large

Asked by MikeR

The Alpha-4 karmic-netbook-remix-i386.iso is *just* over 700MB
This causes a problem with some burning software. If I choose to carry on regardless, the CD boots OK, but running an integrity check shows errors on several (7, IIRC) files.

Should i
1) Ignore the errors (I don't know which files are corrupt)
2) try burning a DVD
3) try burning a (non-standard) 800MB CD
4) wait -- perhaps a future version will fit in under 700MB

Thanks,
Mike

Do you have experience of burning an ISO, or is this your first time? Many people make coasters the first time.

Look at "BurningIsoHowto" on https://help.ubuntu.com/community/BurningIsoHowto - especially the bit about verifying the md5 sum - to check if your ISO is OK

I think that it is fairly normal for ISOs to be a bit over 700Mb, but once burnt properly it will make a disk a bit under 700Mb.

HI :)

The UNR is not made to nor meant to fit on a Cd. It is made specifically for netbooks that seldom even have a cd/dvd drive. Also note the image is not an iso image unlike Server Edition or Desktop Edition. The UNR is designed to put onto a Usb-stick.

Note the Jaunty 9.04 UNR is about 900Mb!

I think there are significant differences in the hardware support as netbooks are still quite a new concept and often have new concepts in their hardware architecture.

Anyway, good luck and regards from
Tom :)

@Tom: Please see
http://cdimage.ubuntu.com/releases/karmic/alpha-4/karmic-netbook-remix-i386.iso
This is an ISO *not* an IMG file. Admittedly not yet an RC version, but still just a trifle too large (708MB) to fit on a standard CD.
Possibly using ImageWriter it could be put on a USB memory stick, but that is not its primary purpose, as it makes a bootable CD. An IMG file OTOH can only be used on a memory stick.

@arochester: I have been downloading and burning ISO files since Ubuntu V 5.04.

Hi MikeR, I am expressing some thoughts that may help:

Alpha versions are made for 'testing'.
UNR is primary intended to be used on netbooks (where a CD-drive not exist).
ISO format is usually for burning a CD, but also it is used to 'burn' a 'live USB stick' using 'USB startup disk creator', running any Ubuntu installation or live CD (9.04 or 9.10 from top menu System > Administration > USB startup disk creator).

So I believe the primary purpose of a UNR .iso file is to be written to a USB stick using 'USB startup disk creator'. Note also that using this program you can test any Ubuntu version on a netbook 'burning' the USB stick with the appropriate .iso (I am running 8.10, 9.04, 9.04UNR, 9.10 alphas and 9.10 UNR alternatively on my EeePC 1000H using this method!).

Regards,
George

Wow, thanks chaps. I haven't looked at the Karmic alpha versions yet and hadn't realised it was still in iso format. I would guess that will change sometime soon. I guess it's still all very new.
Thanks and regards from
Tom :)
