You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by switching back to a branch. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -c with the switch command. Example: git switch -c Or undo this operation with: git switch - Turn off this advice by setting config variable advice.detachedHead to false HEAD is now at f2260e5 Packages requirement update and version update (#381) [rtd-command-info] start-time: 2026-02-23T17:05:40.516856Z, end-time: 2026-02-23T17:05:40.560331Z, duration: 0, exit-code: 0 cat .readthedocs.yaml # .readthedocs.yaml # Read the Docs configuration file # See https://docs.readthedocs.io/en/stable/config-file/v2.html for details version: 2 build: os: ubuntu-22.04 tools: python: "3.11" apt_packages: - graphviz sphinx: configuration: doc/conf.py python: install: - requirements: doc/requirements.txt [rtd-command-info] start-time: 2026-02-23T17:05:41.585900Z, end-time: 2026-02-23T17:05:47.298261Z, duration: 5, exit-code: 0 apt-get update --assume-yes --quiet Get:1 http://security.ubuntu.com/ubuntu jammy-security InRelease [129 kB] Hit:2 http://archive.ubuntu.com/ubuntu jammy InRelease Get:3 http://archive.ubuntu.com/ubuntu jammy-updates InRelease [128 kB] Get:4 http://security.ubuntu.com/ubuntu jammy-security/restricted amd64 Packages [6538 kB] Get:5 http://archive.ubuntu.com/ubuntu jammy-backports InRelease [127 kB] Get:6 http://archive.ubuntu.com/ubuntu jammy-updates/universe amd64 Packages [1613 kB] Get:7 http://security.ubuntu.com/ubuntu jammy-security/multiverse amd64 Packages [62.6 kB] Get:8 http://security.ubuntu.com/ubuntu jammy-security/universe amd64 Packages [1301 kB] Get:9 http://security.ubuntu.com/ubuntu jammy-security/main amd64 Packages [3737 kB] Get:10 http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages [4096 kB] Get:11 http://archive.ubuntu.com/ubuntu jammy-updates/multiverse amd64 Packages [70.9 kB] Get:12 http://archive.ubuntu.com/ubuntu jammy-updates/restricted amd64 Packages [6818 kB] Get:13 http://archive.ubuntu.com/ubuntu jammy-backports/universe amd64 Packages [37.2 kB] Get:14 http://archive.ubuntu.com/ubuntu jammy-backports/main amd64 Packages [83.9 kB] Fetched 24.7 MB in 4s (5555 kB/s) Reading package lists...
