Help! Creating clone from a cosmic installed bootable USB stick;
I have a working running USB stick with lubuntu 18.10 cosmic on it. I installed the stick by a normal lubuntu 18.10 .iso.
Now I learned, or always understood that cloning a linux system is easy. Today and yesterday I learned in practical experience it is not. Result is a not working 2th usb stick and even partition manager doesn't like it.
What I do:
I use that syntax of the dd command to clone my working linux installed bootable usb stick to another usb stick. I do this by using a third lubuntu installation. In other words, I do not try to backup an active running lubuntu session itself. Yesterday I tried backingup from the running system , it didn't work. Than I found topics stating that this method doesn't result in a readable usb clone, so today I decided to use usb stick number 3 which is starting an external Linux system so I can clone usb stick1 to usb stick number 2.
Complex? Maybe, but I wanted to be sure everything is tested out. And using this context:
sudo dd if=/dev/sdx of=/dev/sdy bs=8M && sync
Doesn't work at all. Result: It creates a clone usb stick. Whne I try to run it, the grub comes up, I can select lubuntu, I see it starting ,the . . . . dots come on the screen which creates hope. Than The system falls back in a initdos or puppydos prompt (or whatever it is called,) I tried to do a fsck command on the patition, rebooting, didn't work. In fact it seems to hang on a video driver or something. But how is that possible if the system is supposed to be an exact clone of the working usb? I can run mc midnight commander, when I type it in the prompt screen (I installed mc before backing up at the system of the original usb stick).
To complete my story I must add, that I also tried to dd backup first to the internal harddrive, before restoring it on usb stick 2. Didn't work either.....
Would there by anybody out there, whom found a way to do what I want to do for a lubuntu cosmic 18.10 USB running sytem?....
I know there are tools like clonezilla and stuff, but doing what I tried should work. Why doesn't it? Does dd only work when you restore the backup on the same usb stick? (note that both usb devices I used are not of the same brand, but have the same size, 32gb....)
Some help required.
update: i forgot to mention 2 more things:
1.On the USB stick wih my working install, I have 2 partitions. A ext4 / system partition and a small 6 gb NTFS partition I use for sharing files. I tried dd if=dev/sdd and if=dev/sdd1 , same end result.
2.The installation of the original usb stick is based on a UEFI partition table! The bios in my laptop is set on UEFI as well. Just in case it is important...
