* Update CI nix version For `--option http2 false` to take effect requires Nix 2.3.2. CHANGELOG_BEGIN CHANGELOG_END * Set option `http2 = false` dev-env nix config This is less likely to overlook an instance than manually adding `--option http2 false` to each Nix invocation. Setting `--option htt2p false` also had no effect on the multi-user Nix installation on the Linux CI machines due to ``` WARNING: option '--disk_cache' was expanded to from both option '--config linux' (source /nix/store/2xnfb2l39d2b4nxw5vwmqz5hjwhw0caw-daml-bazelrc) and option '--config linux' (source /nix/store/2xnfb2l39d2b4nxw5vwmqz5hjwhw0caw-daml-bazelrc) ``` Co-authored-by: Andreas Herrmann <andreash87@gmx.ch>
