For me 2.02-54 still breaks the boot on my thinkpad x220 (running in EFI mode, no secure boot on this system, doesn't support it). I still get the grub shell/commandline instead of booting the system or option to choose which entry to boot. Reverted back to 2.02-51.
For me this update breaks boot on f29 system x86_64 EFI (older EFI without secure boot on thinkpad x220). I don't get the error message like in bug #1624532, but just get a grub commandline. Downgrading to 2.02-51 I can boot again.
I'll leave neutral karma, but arduino "ide" doesn't start, nothing happens, if you execute it manually /usr/bin/arduino Error: Could not find or load main class processing.app.Base
