    v0.202605.117 Stable

    pcdoyle released this 2026-05-04 21:59:23 +00:00 | 6 commits to main since this release

    Changes

    • Fixed bug that affected AlmaLinux 10, a kprobe preflight check was left in with the kmod preflight checks and AlmaLinux 10 failed when installing kmod when it didn't need to fail.

    Automatic Install

    Auto-detects your arch, downloads the right binary into $(pwd), and verifies its SHA-256 against the published SHA256SUMS:

    curl -fsSL https://copyfail.pcdoyle.dev/install.sh | sh

    Always grabs the latest release. Exits non-zero on checksum mismatch and removes the bad file.
