i tried using the curl command they say leads to an error from powershell (curl.exe -fL -o "C:\ghcup\tmp\ghcup-3da46c8d7d5a204f\ghc-9.2.5-x86_64-unknown-mingw32.tar.xz.tmp" "https://downloads.haskell.org/~ghc/9.2.5/ghc-9.2.5-x86_64-unknown-mingw32.tar.xz") it also throws an error: "curl: (35) schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) -"

You can pass options to Curl via the GHCUP_CURL_OPTS environment variable.

According to Google Translate, the Russian "sub-error" message after the error code reads "The revocation function was unable to perform a revocation check on the certificate." So, it may be sufficient to pass the somewhat safer --ssl-revoke-best-effort or, failing that, the --ssl-no-revoke flag, which will only shut off the revocation check, rather than the -k flag which allows for completely insecure connections.

In short, in PowerShell, you may find that it's sufficient to run:

$Env:GHCUP_CURL_OPTS = '--ssl-revoke-best-effort'

before running ghcup.

It's a bit of a concern that the revocation check is failing, though. If you try to access https://downloads.haskell.org via a web browser, do you get any similar errrors?
