Not in the Catalog at the moment. Should come up in the next few days I suppose... Thanks for the heads up anyway. Time for some testing.
Hmm, not installing on a fully patched Windows Server 2019 with a previous version of KB4486153 which is somehow expected. The current patch level (2020-11) is Package_for_DotNetRollup~31bf3856ad364e35~amd64~~10.0.4270.1 The refreshed .NET Framework 4.8 is Package_for_KB4486153~31bf3856ad364e35~amd64~~10.0.1.3307 while the existing installed version is Package_for_KB4486153~31bf3856ad364e35~amd64~~10.0.1.3106 superseded obviously by the .NET Framework CU. Probably without the CU or with a lower version like the built-in 4.7.2, the refreshed version would install without any issue.
The components collide is not new for .NET packages https://forums.mydigitallife.net/th...0558-net-framework-3-5-4-5-2-4-6-4-6-1.77505/ that's becuse the new KB4486153 and the CU KB4586877 contain components with same version, but different hashes so they will not work together i should have tested the new KB4486153 before posting
For what it's worth, .msu links are dead now but .cab links still work, and still the same problematic package 10.0.1.3307

The warning was because of this post: https://forums.mydigitallife.net/threads/windows-10-hotfix-repository.57050/page-569#post-1636024 Implying that the latest .Netfx35-48 CU is not supported with the new .Netfx48 package, then better to just use the older .Netfx48 package and use the latest .Netfx35-48 CU.
Components with same version but different hashes likely explain the errors which I see in CBS.log when trying to install the newer release on top of the previous 2019-12 release, even without any CU for .NET 4.8 installed. There are many good things introduced in Windows 10 and the equivalent server versions but there are few areas which are messy beyond redemption and the update mechanism is one of them.
It is in fact the same with the late 2020-10 Preview Update, promoted to regular update for lack of a better option. I think it is commonly encountered for the .NET CU updates not designated as "Security Update", but "Update" only. EDIT: Sorry, I noticed that I was making reference to the earlier update instead of the later 2020-11. Ignore this post.
At least we now know that the latest .netfx35-48 CU is not working with the latest .netfx48 package but the older .netfx48 package does and then you are on the most uptodate level
As far as I know, there is no official .exe version of the Jan 2020 (signed Dec 2019) release. The official one is still the 26 July 2019 signed release. After applying one of the recent .NET Framework 4.8 Monthly updates, the base version should no longer matter as far as I can tell, other than showing different base versions.
