yakkety server: fails to detect and mount CD-ROM

[Jason Gerard DeRose]

The latest yakkety server amd64 daily (20160921.1, sha1sum b3e9f59397389bf23390f4869d3aef46de5d105c) fails to detect and mount the CD-ROM.

Please see attached screenshot.

I confirmed that this is happening on physical hardware when booting the server installer from a USB stick (I tested in both UEFI and BIOS mode, both fail).

This also happens under QEMU in BIOS mode. I can't test under QEMU in UEFI mode because of lp:1624096

Thanks!

Status changed to 'Confirmed' because the bug affects multiple users.

[Steve Langasek (vorlon)]

Transient bug in a non-promoted image due to package pool mismatch. Will be fixed in next build.

Still an issue with 20160922

Testing with the 20160924 ISO resulted in the same error.

Typical QEMU CLI:
# qemu-img create -f qcow2 vdisk.img 4G
# qemu-system-x86_64 -enable-kvm -boot d -hda vdisk.img -cpu host -m 1024 -cdrom yakkety-server-amd64.iso

Using SATA CD-ROM drive as suggested on IRC, also errored at the same place:
# qemu-system-x86_64 -enable-kvm -boot d -hda vdisk.img -cpu host -m 1024 -device ahci,id=sata0,bus=pci.0,addr=0x8 -drive file=yakkety-server-amd64.iso,format=raw,if=none,media=cdrom,id=drive-sata0-0-0,readonly=on -device ide-cd,bus=sata0.0,drive=drive-sata0-0-0,id=sata0-0-0,bootindex=1

Bug 778319 is about a similar (if no the same) issue. Could you try the workaround described in comment #7?

"Solution (that needs manual intervention) that works for me
# ALT+F2 to go to the shell, umount /media && mount /dev/sdb /cdrom
(supposing that the flash drive is /dev/sdb)"

[Joshua Powers (powersj)]

When I try there are no /dev/*sd* devices to even try to mount and /media is not mounted or anything there.

Appears fixed with 20160926. System installed fully and booted an install system. Automated smoke tests for amd64 and i386 have passed and more in-depth tests are in progress.

I'm setting this to Incomplete since it appears to be fixed.

[Jason Gerard DeRose (jderose)]

Ah, sorry, I forgot to follow up on this. Yes, the bug has been fixed for about a week now (but I was on vacation).

Is it better to mark this as Fix Released instead?
