Hi Thomas,

>The error message of losetup does not match this theory.

Re-reading http://ix.io/3v6K and it does appear that possibly
/mnt/src/host/ does exist based on some of the debugging output.
Thanks for making me look back. I made this "theory" on trying to `ls
/mnt/host/src/rc/build/images/kukui/R94-14125.0.2021_08_05_1510-a1/chromiumos_base_image.bin`
after the script had been executed. I received an error the path
didn't exist. But perhaps it was cleaned up after the script finished
executing.

>Is there a hard reason why you don't show the output of  losetup -l -a

I will now modify the script and also provide before and after below:

before:

(cr) ((b1688d0...)) colin@M00974055-VM ~/chromiumos/src/scripts $ losetup -l -a
-bash: losetup: command not found
(cr) ((b1688d0...)) colin@M00974055-VM ~/chromiumos/src/scripts $ sudo
losetup -l -a
(cr) ((b1688d0...)) colin@M00974055-VM ~/chromiumos/src/scripts $

no output appears

during:

I've added losetup here:
https://github.com/drocsid/cros-scripts/blob/feature/deb11-II/common.sh#L641

ourput after running ./build_image
https://chromium.googlesource.com/chromiumos/docs/+/main/developer_guide.md#Build-a-disk-image-for-your-board
with above changes: http://ix.io/3vfj

after:

colin@M00974055-VM:~/chromiumos/src/scripts$ cat ~/losetup-error.txt |
curl -F 'f:1=<-' ix.io
http://ix.io/3vfj
colin@M00974055-VM:~/chromiumos/src/scripts$ losetup -l -a
-bash: losetup: command not found
colin@M00974055-VM:~/chromiumos/src/scripts$ sudo losetup -l -a
[sudo] password for colin:
colin@M00974055-VM:~/chromiumos/src/scripts$

no output appears.
