This video will show you how to change the old code of your personal conkys to the new lua syntax.
There is a script you can use.
Here is the official website of the conky.
We have taken the convert.lua on 02/09/2020 from here.
If the converting script does not work anymore in the future,
- tell us and we put the latest version in the ArcoLinux conky package
- get the new convert.lua from the github
and try again.
Still no success. Make an account a github account and ask the developer of conky what to do.
