Hi,

Try to list the available lava versions in your distro initially using the command "apt policy lava" and downgrade using "sudo apt install <package version>" .

But, there may be cases in which you must resolve some dependencies to be able to downgrade the package through.

Hope this may helps you i.e https://www.linuxuprising.com/2019/02/how-to-downgrade-packages-to-specific....

*Note*: We have not tried this so far. AFAIK before executing these commands, make sure you take the backup of your lava modified/configuration files which you have changed for your production/running setup.

Best of luck!!.

Regards, Koti
