I cannot install macOS Catalina on my iMAC. It stops mid-installation and informs me an error has occurred. This is my 6th attempt

After 6 attempts, I still cannot install macOS Catalina on my iMac. It stops after about 3 minutes to inform be that an error has occurred and to try later. At one juncture, it directed that I restart the computer. Still no success.

iMac 21.5″, macOS 10.14

error message updating to OS 10.15.7 Catalina Hello everyone, When trying to upgrade the Mac OS of a late 2013 iMac to Catalina, I get an error message. At first it wouldnt even download the update and gave an error-message (how Windows, I thought Apple... 'just works'?) Then I did countless things like pressing buttons and pulling plugs while starting up, and it actually worked. The upgrade was was downloaded and installing could commense! YESS! Then, during installation, right after the computer should start up again to install the update, I get a NEW error message (how Windows is that!??), the new error message reads: An error occurred while preparing the installation. Try running this application again. Yeah... ok, did that. Like 4 times, which did nothing. Does anyone have a clue what to do?? Before installation the computer prompted me that Adobe Application manager and Openoffice.org will not work anymore after the install, so I deleted them (yet I still get a message Adobe application manager will not work anymore)

What year is the computer and does it qualify for Catalina ? If yes, try restarting computer in Safe Mode ( Shift key ) immediately at startup. Still not go, the internal drive does require at least 20+ GB free and empty space
