, the version printer returns "nix (Lix, like Nix) 2.x", hence the `daemonVersion` was being set to the string "like". Using `compareVersions` with a letter compares them lexicographically: builtins.compareVersions "like" "2.12pre20230103" // => -1 builtins.compareVersions "like" "2.16.0" // => -1 This caused that `isDaemonNewer` always returned 1, falsy in Bash terms. Therefore, the test suite skipped those tests where they use it. Fixes lix-project/lix#324 Change-Id:If6682515bf0bf8b8add641af9a4e98b50a9acb51
