We now have a 26.04 release candidate ready for a final round of testing. It is available for download at https://cdimage.ubuntu.com/daily-live/20260420.1/resolute-desktop-arm64.iso. There is also a server iso that should work available at https://cdimage.ubuntu.com/ubuntu-server/daily-live/20260420.1/resolute-live-server-arm64.iso
Tests results can be reported at Test Observer (or Test Observer for server) by members of the open-registration ubuntu-testing launchpad team. See Retiring the ISO Tracker! Introducing tests.ubuntu.com for 26.04 LTS for more info on the test process.
