How to I check whether my installer is corrupt?
1 answer
Ive been having problems doing a Ubuntu install (ubuntu 18.10 optimus dual boot hang on first boot (Dell 7567 )) and think it may be the USB stick was not written properly. How can I write and verify the image (was using windows to do this but do have another Linux box I can use to make the USB). I know there is a verify in the installation menu but would rather do it manualy (i.e. with CLI).

For that purpose USB has a file md5sum.txt
- Plug in the USB drive in any Linux OS.
CD to USB drive
cd /media/$USER/<drive name>
Run
md5sum -c md5sum.txt | grep -v OK || echo "All OK"
If there is a defect, output is something like
md5sum: WARNING: 1 computed checksum did NOT match
If not
All OK
No output means all OK.
For full report run
md5sum -c md5sum.txt
So this means that is is both downloaded and copied to USB without errors?
