Missing packages are not installing autometically on Ubuntu 20.04 LTS

[rafisics]

I using currently using MikTex 21.3 on Ubuntu 20.04.2 LTS.
On the MikTeX Console settings, the option for installing the missing packages (on-the-fly) is turned on. But today, I found out it's not working.
For example, I wanted to use the package enumitem:

\usepackage{enumitem}

While compiling with Texmaker, it showed:

! LaTeX Error: File `enumitem.sty' not found.

I tried it compile it with Sublime Text editor too, but I faced the same issue.

To get it done, I had to manually install the missing packages from MikTeX Console. What else should I need to do to activate auto-install the packages while compiling?
