Hi,

I use Xubuntu 24.10, but have also Ubuntu and Xubuntu 24.10 in Virtualbox. I wanted to try 25.04 (plucky) and tried to upgrade both. I did apt update && apt upgrade first, reboot, then sudo do-release-upgrade -d. I get the welcome message, press Y to Continue, then I get this (in both - Ubuntu and Xubuntu):

Get:1 Upgrade tool signature [833 B]

plucky: error: no such option: --mode

I understand that the “Permission denied for _apt user” is only warning and it’s run as root, but the last line seems like an error and bug.

Anyone tried to upgrade from 24.10 to 25.04 and was successful?
