Howto: Track previous versions.

[FireWizard]

Because of recent problems caused by update to beta 13017, the question has been raised (on Github):

What build did you use before updating to build 13017?

This question might be important in order to trace the version where a possible bug could have been introduced.

In this case an answer has been given:

I don't know what build I had before. One of the beta from yesterday.

In fact, it is quite easy to find the previous installed versions.
It is explained below.

Most users will run Domoticz as a daemon, so that it starts automatically, if rebooted or if there has been a version upgrade.
Log in with ssh into a terminal and issue the following command:

Code: Select all

cat /var/log/daemon.log|grep domoticz.sh

As an example, the result will be:

Code: Select all

As you can see, the exact time that a particular version of Domoricz has been started, is shown.
This can be useful information in case of problems, which have to be tackled.

I am testing with the updatebeta.sh to make a copy of the domoticz folder (without backups) to facilitate an easy roleback.
