Public bug reported:
I have an HP ZBook 15 G2 on which I run Windows 10 from the internal
drives, and occasionally boot to Ubuntu from an external SSD drive.
Drives are:
sda 256GB SSD hosting Windows OS (Bitlocker encrypted)
sdb 512GB SATA hosting data (Bitlocker encrypted)
sdc 128GB SSD mounted via USB3 caddy
I downloaded the Cosmic desktop ISO and verified the SHA256 hash.
I used ether to copy this to two different 4GB USB sticks - I had the same
issue with both.
Both writes were verified as accurate by etcher.
I booted the laptop to the 4GB USB stick by pressing F9 during boot and
selecting that device.
I selected the USB3 attached SSD as the installation disk.
The installation proceeded normally but gave a fatal error installing Grub.
Reselecting the Grub install as /dev/sdc did not work - Same error.
I rebooted to SDC using F9 and got a black and white Grub screen.
I was able to repair the Grub environment by setting the root and manually
loading the kernel and initrd.
I repaired the grub environment using grub-setup and was able to reboot
normally.
Everything seemed normal but after installing Wireshark and Pidgin,
there would not run because of missing files. Reinstalling the relevent
packages fixed the missing files.
I installed debsums and could see there were hundreds of missing files -
Too many to manually reinstall.
I worked around the problem by mounting the USB SSD under a new VM in
Virtualbox and installing from the ISO in the VM. The system worked
normallt once rebooted to the USB3 ISO.
Not sure if this is caused by Etcher?
