Any idea what could cause this win32-network problem on a debian 10 KVM ?

After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, Win32-network
It’s probably my ghc version. I used the latest (8.10.1) when cardano-node needs 8.6.5
Unfortunately this version is not readily present for debian 10. I may have to compile the ghc or try the nix approach.
… (latter edit)… the best solution is to use ghcup to handle concurent ghc version.
from iohk’s docs
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
Then use ghcup to install ghc 8.6.5 on debian 10. In the end, It will simply install the deb9 version of ghc 8.6.5, and it works.
Maliky I was just trying to install my cardano node in AWS but after trying the comand cabal build all I get the error message that follows Warning: Requested index-state2020-07-15T00:00:00Z is newer than ’hackage.haskell.org’!

I already tried puting this command curl --proto ‘=https’ --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh and installed everything from there but the message persists.
was getting these errors yesterday. but I was also mainly relying on my previous experiences and pieces of turorials here and there which are by now outdated. Once I checked the official docs I saw that recent cardano-node (1.30.1) requires ghc 8.10.4, then I made sure to install the required Debian/Ubuntu packages before that and problem solved
Also, latest cardano-wallet v2021-09-09 complained about ghc version above. It requires 8.10.5, so I did this:
