How to Install Algernon Silently with winget on Windows

Setting up Algernon on a fresh Windows install? Here's the cleanest one-line winget command for an unattended, no-clicks install — perfect for new-machine provisioning, golden-image scripts, and Task Scheduler jobs.

Quick answer

Open Terminal as Administrator and run:

winget install --id xyproto.algernon -e --silent --accept-package-agreements --accept-source-agreements

Algernon: Small self-contained pure-Go web server with Lua, Markdown, HTTP/2, QUIC, Redis and PostgreSQL support

Typical install time: 10–60 seconds depending on installer size.

What gets installed

Field	Value
Package ID	`xyproto.algernon`
Publisher	Alexander F. Rødseth
Installer type	ZIP archive
License	BSD-3-Clause
Latest version	1.17.8
Last release	5/24/2026
Minimum OS	Windows 10+
Homepage	github.com

ZIP packages extract to a target folder — no installer UI to suppress.

Per-user install (no admin)

If you don't have admin rights, try per-user scope:

winget install --id xyproto.algernon -e --scope user --silent

If the manifest doesn't have a user-scope installer, winget falls back with an error — in that case you genuinely need admin or use the Access denied fix.

Specify a version

To pin a known-good version (useful for reproducible CI / team standardisation):

winget install --id xyproto.algernon -e --version 1.17.8 --silent

List available versions:

winget show --id xyproto.algernon --versions

Override silent flags

If winget's --silent doesn't fully suppress the installer's UI, pass native flags via --override:

winget install --id xyproto.algernon -e --override "n/a"

For this installer type, override flags aren't typically needed.

Verify after install

winget list --id xyproto.algernon

If the version is shown, the install succeeded.

Upgrade silently

winget upgrade --id xyproto.algernon -e --silent --accept-package-agreements --accept-source-agreements

Or upgrade as part of a bulk weekly cron — see How to update all Windows apps.

Uninstall silently

winget uninstall --id xyproto.algernon --silent --disable-interactivity

In a provisioning script

PowerShell snippet for unattended Windows setup:

$apps = @(
  "xyproto.algernon"
  # add more packages here
)

foreach ($id in $apps) {
  winget install --id $id -e --silent `
    --accept-package-agreements --accept-source-agreements
}

Wrap in Task Scheduler for one-shot machine provisioning. See Fresh Windows 11 setup.

Common errors

"Algernon is already installed" — winget detected the existing install. To force-reinstall over the existing copy:

winget install --id xyproto.algernon -e --silent --force

"Installer hash does not match" — Alexander F. Rødseth published a new version before the winget manifest updated. Wait ~24 hours or pass --force. See hash mismatch fix.

"Access denied" / 0x80070005 — run Terminal as Administrator. See Access denied fix.

0x80073D02 — package in use — Algernon is currently running. Close it then retry. See package in use fix.
