I installed texlive 2020 some time ago without any problems. While updating it some issue with luatex occured and luatex stopper working. So I uninstalled texlive and decided to reinstall it.
However, the installation fails when trying to download luatex:

Will be retried later.
I switched to minimal installation to save time, tried different mirrors, but still get the same error.
I am running Windows 10 as administrator with Avast turned off. The same problem occurs on the other machine as well.

Installation failed.
Rerunning the installer will try to restart the installation.
Or you can restart by running the installer with:
install-tl-windows.bat --repository http://mirror.datacenter.by/pub/mirrors/CTAN/systems/texlive/tlnet --profile installation.profile [YOUR-EXTRA-ARGS]
or
install-tl-advanced.bat --repository http://mirror.datacenter.by/pub/mirrors/CTAN/systems/texlive/tlnet --profile installation.profile [YOUR-EXTRA-ARGS]
Best Answer
I had the same problem and the same error messages reinstalling TexLive, both on clean Windows and during an upgrade.
As a workaround, you may download the TexLive2020 ISO and use it instead of the network installer which is searching the latest package repo. Present ISO has date 2020-04-06. You may find the download at CTAN Directory systems/texlive/Images or follow the link: https://ctan.org/tex-archive/systems/texlive/Images
After mounting the image, run the "install-tl-windows.bat" as admin and follow normal install (verify that the install is pointing to the ISO and not net.repo).
