Hey @MikeRL, thanks for the report. And thanks for chiming in @joelhuebner. My teammate who maintains Etcher responded with this in another post:
We had to upgrade the
electron-buildermodule to version 21 which doesn’t include that functionality anymore, so while it’s not done 100% intentionally (as in, not for that reason), we had to upgrade for a number of other reasons (e.g. support for newer macOS Catalina)
We are tracking this issue in our github page: Missing Application Icon for 64 bit Linux AppImage · Issue #2371 · balena-io/etcher · GitHub We’ll follow-up when we make progress.
So you could perhaps follow Joel’s suggestion for now.?
