I have a MacBook Air (13-inch) and currently on Version 10.15.1 with 15.5 GB of free space, I've been trying to update it to macOS Catalina 10.15.3 and a restart is required. My Mac restarts, but never updates and prompts me with the same thing every time.
Any help on what I should do? Any solutions?

15.5 GB is insufficient free space. Even with 128 GB, you need a bare minimum of 20 GB free to install it.
Turn off Time Machine once your backup is complete, and then try to do the combo update.
Backup any data that you don't use frequently to two other hard drives and/or flash drives, or use Carbonite or Cloud backup options such as iCloud, OneDrive, or Google Drive.
A general rule of thumb, though not documented anywhere as a manufacturer requirement is to keep at least 15% of your disk space free for swap files and temporary files not to get in the way of installs.
That basically means:
20 GB for 128 GB,
40 GB for 256 GB
80 GB for 512 GB
160 GB for 1 TB.
It will also keep your system running smoothly.
Only upgrade when you have a genuine need to run something that won't run any earlier.

Try the combo installer while in Safe Mode.

Thank you so much, I'm going to clear up some space being that I purchased an external hard drive! I really appreciate it!
Thanks!
Also, that helped to solve my problem and I found other ways to clear up space!
Thank you again!
CAN'T UPDATE to macOS Catalina 10.15.3
