I have given up!
I downloaded the 64 bit Etcher zip on Ubuntu. I extracted the files. I made sure the installer was exicutable. But there it stopped! Whatever I tried it just wouldn’t install.
I looked for a 64bit app image but I couldn’t locate an App image I was confident in.
Finally I just used Disk Creator - which has been so straightforward and reliable.
I’m willing to accept it’s me! I want to go back to living Etcher but until i can install it without effort it’s just not something I will entertain.
I find lots of threads on this with varying success - is there a plan to remedy these issues and return to a reliable installation option?
