livecd-iso-to-disk fails to create liveusb for Fedora Workstation 37 Beta iso

[laolux]

I am using Fedora 36 to create a liveusb for Fedora Workstation 37 Beta.
As root I run livecd-iso-to-disk --format ext4 /home/user/Fedora-Workstation-Live-x86_64-37_Beta-1.5.iso /dev/sdb

This fails with

Source image is '/home/user/Fedora-Workstation-Live-x86_64-37_Beta-1.5.iso'
Verifying image...
/home/user/Fedora-Workstation-Live-x86_64-37_Beta-1.5.iso:   3a59d1f243057ea068d29e10a68274a1

Fragment count: 20
Supported ISO: no
Press [Esc] to abort check.

The media check is complete, the result is: PASS.

It is OK to use this media.
Error 1 detected at line 2028 /usr/bin/livecd-iso-to-disk

The error does not appear when I use an image for Fedora Workstation 36 Beta. In this case the tool seems to work fine.

Note: The issue seems related to #244

Yes, the .iso image structure has changed with Fedora 37. A new version of livecd-iso-to-disk will be required. I'm testing that now.

[laolux]

Great that you work on this already! I would be happy to help testing, either now or when the package hits bodhi.

Hi @FGrose

Would the next version of livecd-iso-to-disk you're working on, fix the #244 ?

My contribution: The later issue seems to specific to the .iso files of Silverblue since at least release 35. (I've reproduces it for releases 35, 36). For Silverblue 37 I will test after it's final release date in a couple of weeks )

The only workaround I've found to far is to revert to livecd-tools-27.1 that was included in Fedora 34 but now EOL

My coding skills are very limited; it seems to me (IMHO) :

1. a glitch might have been inserted in releases after livecd-tools-27.1 around 16 month ago: Using blame
   code block v27.1 - L875 uses variable $SRCMNT

While code block v 31.0 #L1402 substitutes unkown variable $SRCMNT$IMGMNT

2. livecd-tools-31.0 still contains references to syslinux. Being not maintained upstream anymore, syslinux has been dropped with the use of GRUB2 when booting the boot.iso on BIOS systems, see change set since the Fedora Linux 37 release

getting same issue on fedora 37 iso .
is older version of livecd-tools work with fedora 37 ?

[bioinfornatics]

same issue here,
As this bug is open since 1 year how people are installing fedora livecd iso to usb disk ?

how people are installing fedora livecd iso to usb disk ?

Fedora Media Writer

Same problem in FC38. The error is caused by the command

lsinitrd /initrd*.img --unpack -f usr/lib/modules/*/kernel -v 2>&1

Namely, the variable CONFIG_SRC failed to be set. And the reason is simply that neither $SRCMNT/isolinux/ nor $SRCMNT/syslinux/ exist at that step in the livecd-iso-to-disk script. Actually, those forlders do not exist in $SRCMNT, at all.

Of course no responses from FC. I don't know why we still report bugs to Fedora. I don't remember the last time one of my bug reports was attended.

I've open a Fedora bug report her last december : https://bugzilla.redhat.com/show_bug.cgi?id=2152842

Waiting for a fix for livecd-iso-to-disk, If you just want to burn your live/install ISO image to a USB stick where you can also store some data, I've created a simple live2usb.sh script. A GPT table with an EFI system partition and FAT32 read-write filesystem is used for that. Tried with Fedora 36 live xfce (ISO with DOS parition table) and Fedora 37 (ISO with GPT partition table).

I've created a simple live2usb.sh script

Thank you for inspiration, @gbuloz. I made my own version with ext4 partition and persistence directory.

I wrote another script to flash Fedora Live with persistent overlay: https://github.com/innovara/yastfli
It supports ext4 and fat32 and the option to choose the size of the overlay image, if you don't go the directory overlay route.
