On my dad's pc , randomly dragonized stopped working. He shut the pc of normally in the morning and when booting in the evening it shows the following errors(both in snapshots and normal boot). I see the following errors when i press up arrow while loading snapshot and normal distro
Dependencies failed for:
Network synchronisation
Random filename
Same "random filename" device
Swap
Systemd service
And a couple of timeout messages
One time I have same issue, that time I upgrade and stopped the process in between and whole system crashed. And not starting after restart. Then I done fresh install.
I would echo @zoner. If you don't want to use dd then my tool of choice is imagewriter as well.
Lot of people prefer etcher as it is cross platform, but because of the changes to etcher I will no longer recommend it. Also, as etcher is an electron app it is huge in size compared to other similar apps for this purpose.
