backup файл от Ubuntu Server 16.04 възстанови openHAB2.5.5 в Ubuntu Server 20.04 на 100%. BasicUI и PaperUI бяха огледални копия в двете системи. MySQL и MQTT Mosquitto са извън обсега на backup файла, което налага инсталацията им от начало в Ubuntu Server 20.04.

ROLLBACK

OH2.5.6 се оказа катастрофа. Не призна иконите в items-файлове. Отказа трансформации от JavaScript. Логично решение откат назад към OH2.5.5.

apt-cache showpkg openhab2 // варианти версии

sudo /bin/systemctl stop openhab2.service
sudo apt-get -y --allow-downgrades -y install openhab2=2.5.5-1

sudo openhab-cli info

sudo openhab-cli clean-cache

sudo /bin/systemctl start openhab2.service
