Congratulations!! for the launch yesterday.
I tried installing/updating my eOS yesterday, But keeps getting error:
ERROR: extraction error: archive extraction failed with status: exit code: 1
I'm using eOS with Dual boot with EFI, running eOS 5.1.7 without any issues(Well no longer now) I'm using Huawei Matebook 2020, I can boot fine in demo mode without any issues.
I've tried validating checksum and it passes validation, even tried 3 different USB sticks but getting same error. Tried using etcher, rufus, some others as well like 100 times but no luck, I've feeling it's not allowing anything to write on disk while installation but I validated it in demo mode that I was able to write on disk fine.
