Hi Phil,



Analogous problem reported 28/02/2022, 10:44; zero response received.  Earlier report appended.



Yes, because it is Windows, connection problems are impossible to debug
over the line, and above all not reproducible.

Please explain "because it is Windows".   What, architecturally speaking, makes Windows "connection problems impossible to debug over the line", what operating system(s) do allow one to successfully "debug connection problems over the line", and what is the architectural difference between the two ?

Feel free to throw your own infinite expertise into the ring and try to
solve the problems, that would be *greatly* appreciated.

At this point :

[1] TeXLive::TLUtils::check_file_and_remove:   removing C:\Users\PHILIP~1\AppData\Local\Temp\RPAddWJRpP\nKUKULiiZu/spectralsequences.tar.xz, but saving copy in C:\Users\PHILIP~1\AppData\Local\Temp\csOK_gsvQ6
[2] TLPDB::_install_data: downloading did not succeed (check_file_and_remove failed) for ftp://ftp.math.utah.edu/pub/tlpretest/archive/spectralsequences.tar.xz
Installation failed.
the diagnostics are confusing; line 1 says that it is attempting to remove C:\Users\PHILIP~1\AppData\Local\Temp\RPAddWJRpP\nKUKULiiZu/spectralsequences.tar.xz but saving a copy in C:\Users\PHILIP~1\AppData\Local\Temp\csOK_gsvQ6, whilst line 2 says that "downloading did not succeed" and goes on to say that "check_file_and_remove failed".  The transcript makes no mention as to what error(s) occurred during the attempt to "check_file_and_remove" — are these errors logged, and if so, where ?  And since "check_file_and_remove" would appear to be operating solely on local files, where do "connection problems" come into the matter ?

Finally I repeat my original question: "If I "Re-run the installer [to] try to restart the installation", will it re-try just the failed part or will it need to download all 4313 packages again ?"
