failed to rename the current executable: %w
Error message
failed to rename the current executable: %w
What it means
ghupdate: the first step of replacing the running executable — os.Rename(oldExec, oldExec+".old") — failed. On this failure nothing has been changed yet (the defer removes the .old name if it exists). Wrapped with %w so the OS-level rename error (permissions, cross-device, text-file-busy equivalents) is preserved.

Solutions
- Check the wrapped error for EACCES/EROFS and grant write permission on the binary's directory to the app user
- Move the executable to a writable location (e.g. a data volume) before using the updater
- On locked/managed hosts, disable ghupdate and update via your package/deploy pipeline
Example fix
# before sudo mv pocketbase /usr/local/bin/ && /usr/local/bin/pocketbase update # EACCES # after sudo chown $(whoami) /usr/local/bin/pocketbase # or place it in a user-writable dir ./pocketbase update
Defensive patterns
Strategy: validation
Validate before calling
// ensure the binary's directory is writable before enabling self-update
execPath, _ := os.Executable()
if err := unix.Access(filepath.Dir(execPath), unix.W_OK); err != nil {
log.Println("self-update disabled: install dir not writable")
} Try / catch
if err := updater.Update(ctx, false); err != nil {
if strings.Contains(err.Error(), "failed to rename the current executable") {
// EACCES/EROFS: fix dir permissions or relocate binary; nothing was changed yet
}
} Prevention
- Install the binary in a directory the runtime user can write to
- In containers, update by redeploying the image instead
- Check ownership of both the binary and its parent directory
When it happens
Trigger: The running binary's file or its directory is not writable by the process; on Windows the executable may be locked; on Linux a read-only mount or no write permission on the install dir. Note rename stays on one filesystem, so EXDEV is unlikely unless the .old path is redirected.
Common situations: Binary installed in /usr/local/bin or /opt owned by root while the app runs unprivileged; container images with the binary on a read-only layer; SELinux denying rename on the exec type.
