hello
I want to setup a new server. Downloaded zentyal-6.0-development-amd64.iso, md5sum is ok. But usb-creator cannot open the iso. Same with 5.1, while 4.2 works fine.
Tried it on a Ubuntu 16.04 and on a 18.04 machine.
usb-creator-gtk says:
GConf-CRITICAL **: gconf_value_free: assertion 'value != NULL' failed
isoinfo: Unable to find Joliet SVD
How can I create a USB stick for installation?
thanks for help, Gerd
