Total freeze after updating a rather fresh oram to Vangelis

ledan · February 6, 2026, 4:33pm

On my rPI5/4GB, i recently had to rewrite a fresh image of Zynthian (32GB flash card) due to previous issues that i had (i also wrote about them recently here in the forum). After flashing the card (and it worked nicely) i just now tried out the Vaporizer2 install also described here (incl. Presets and Waves being put in the suggested places). It didn’t work and i i thought that perhaps Vangelis was needed and one update later, when trying to VNC into the main screen and adding engines the usual way, nothing will react. Its frozen and dead.

No issues getting into the VNC and the UI, its just that nothing will work at that stage.

I tried to update once again (Vangelis) and this is the log output:

Idk if it can give any leads at all.

Beyond yet another fresh burn/install, is there anything worth trying to remedy the as-is?

Edit. Trying to back down to Stable now throws a

Ok, i could revert back to “Staging” and things have stabilized a bit now, e.g. i can once again operate the UI normally All good at my end.
