Howto make USB boot drives

[oygle]

I have been trying to install Kubuntu 20.04.1 to a laptop, however running into many problems. Have been using

mkusb kubuntu-20.04.1-desktop-amd64.iso

and then select the "e" option. Do you think it may require selecting another option ?? Related discussion at https://ubuntuforums.org/showthread.php?t=2452691

@oygle,

I will answer at that other thread.

Thanks @sudodus

@sudodus - just an FYI, the only way I was able to see the "Try" and "Install" options was to follow your advice and use recovery mode (grub) to select the 'Text graphics' option.

I downloaded OpenMandriva and openSUSE Tumbleweed and used Mkusb to create the usb boot device. The usb was created OK, but I got this crash " _user_bin_udevadm.0-crash".
This is on Ubuntu 20.10 with mkusb 12.6.6-1ubuntu2.

Thanks for the heads up.

Please give me more details: Is this an installed and fully updated & upgraded system? Can you think of any particular unusual settings or things installed, or should I troubleshoot this bug in a standard Ubuntu 20.10 system?

I will look into this bug, but I cannot do it at once ...

No hurry.
This is on a standard Ubuntu 20.10 installation

There is as far as I know nothing special.
I thought it might be related to make usb installation media for other distributions, but I tested with a groovy iso and got the crash.
This is a picture of the mkusb console print out.

@P-I H,

Thanks for those details

More questions:

1. Where and when is the message about the crash printed? (I can't see it in your screenshot of the mkusb console.)

2. Is your Ubuntu 20.10 system booted in UEFI mode or BIOS mode?

3. Which locale (language) are you using in this Ubuntu 20.10 system?

[P-I H]

1. usr_bin_udevadm crashes just before the mkusb script is ready. The crash info is in /var/crash
2. It's booted inn UEFI. BIOS is set to only boot in UEFI mode
3 it's English(United States), but formats is Sverige and keyboard is swedish.

Used mkusb on another computer with Hirsute and kernet 10.4 and didn't get any crash.
I suppose the crash depends on the installation
This is a picture of parts of the crash report. I didn't get the dialouge to report a bug in launchpad.
