error to flash ubuntu

when I flash ubuntu in my usb pen it says: “The writer process ended unexpectedly.” why? what can I do??
thanks

Hello, please provide the operating system and the version, BalenaEtcher version and what image were you flashing onto your pendrive. Thanks!

the last balenaEtcher version and the last version of ubuntu desktop

My version is MacOS 10.15.5

Does Etcher work on any other drive?

No

Hi, just to be sure: you’re running balenaEtcher v1.5.101 on Ubuntu 20.10? You can check the version in the settings.
If not, I’d suggest trying with that and if the issue still rises, open the dev.tools console with cmd + opt + i and paste here the logs so we can take a look at them.

I’m use a Mac for install Ubuntu.

Thank you for the correction, I misread the previous message and then forgot to update that part.
Please paste here the logs from the console when the issue happens again so we can take a look at what’s happening.

THIS?

Hi. Can you try sudo /Applications/balenaEtcher.app/Contents/MacOS/balenaEtcherto see if it works with elevated permissions?

no it doesn’t go

Could you share the output of trying to run the command with sudo please? It’s unclear whether the issue is the admin access or not.

Hi, can you explain what happens, when you start etcher as sudo ? You posted the command console output. Can you please post the output of the browser console as before ?
