The core update 2026.6 on my home assistant system on a RPi4 stops at 35 - 48 % of the proces. Without an error message.
Installed core is 2026.5.4.
Do you have enough free space? Try to follow the supervisor logs while you do this via ha supervisor logs -vf.
Hi Bram, are you talking about the core component with a HAOS setup or core in venv?
core in HAOS
In the log I saw some yellow warning lines. To be sure I ran the update again. And of course it ended normally. with the new core installed.
There were some still some warning lines in the log:
