Hi, i'm trying to write ubuntu 19.04 image to my 16GB SD card.
Because the error pops up every time though I changed SD card, I think it's software problem.
It throws error every time I try. I couldn't find solution myself, and I need your help.
I tried writing after turning off Avast antivirus.
Please let me know how can I fix it.
Thank you.
