Timeshift automatic backups not working

My automatic periodic backups are not working for timeshift.

Upon googling, I came to know that cronie.service is not working. But I don’t have a cronie.service. I think cronie.service is for arch and not for ubuntu. All the solved issues included enabling cronie.service. But all these issues were for arch distro.

But I use Ubuntu 20.04, and cronie.service is not available for me.

Am I missing the cronie.service or is it not for ubuntu?

Bug report on github

My timeshift version is 20.03.
