I wanted to downgrade from 2026.8 to 2026.7.4. in terminal/ssh, ‘ha core --help’ says:
Furthermore, some options can be set and allows for upgrading/downgrading
Home Assistant Core.
Example:
ha core update --version 2021.11.5
current system info (ha info)
arch: aarch64
channel: stable
docker: 29.6.2
...
hassos: "18.2"
homeassistant: 2026.8.0
hostname: homeassistant
logging: info
machine: raspberrypi5-64
...
operating_system: Home Assistant OS 18.2
state: running
supervisor: 2026.07.5
and ‘ha core info’ says:
machine: raspberrypi5-64
port: 8123
ssl: false
update_available: false
version: 2026.8.0
version_latest: 2026.8.0
now, I try ‘ha core update --version 2026.7.4’
Processing... Done.
Command completed successfully.
and core restarts, but afterwards, I am still on2026.8:
update_available: false
version: 2026.8.0
version_latest: 2026.8.0
I just stumbled on the supervisor logs; it looks like the 2026.7.4 was installed, but crashed, so it rolled back the downgrade:
