I had a subject called Operating Systems during my graduation. All the assigments were to be done on Linux environment, preferably, Ubuntu. So, my professor indirectly introduced me to Ubuntu in 2017.
I started using Ubuntu, apart from doing assignments, primarily because whenever I had some urgent work, my main operating system (at that time) started to update. Initially I used Ubuntu as the second option in case the earlier said operating system starts updating again when having urgent work. But slowly it became my primary.
A year ago I thought of migrating to Fedora and installed that in a virtual machine but I was very much habitual of APT. So I stayed with Ubuntu.
