Lost my log file last snap shot stop writing to files

Check the announcement:

A breaking change is the switch from log4j to log4j2, because this changes the expected syntax in the file org.ops4j.pax.logging.cfg. For this reason, the file is overwritten by the update (if you are using APT, please choose “Y” when being prompted for that file). Your old version will be saved as org.ops4j.pax.logging.cfg.bak (resp. org.ops4j.pax.logging.cfg.dpkg-old for APT). So if you have done manual changes in your logging configuration, please note that they won’t be considered anymore.

and: Logging stopped after update to openHAB 2.2.0 Build #1010 + Log4j2 Sample Config
