Weik.io 2026.2.1, published 28 October 2026. The install scripts check the release's checksums before they place the CLI.

Install the CLI

$ curl -fsSL https://weik.io/install.sh | sh

On Linux x64 the script installs ~/.local/bin/weikio after checking it against SHA256SUMS. The line needs curl and ca-certificates, which minimal images such as debian:12 don't have, so install them there first with apt-get install -y curl ca-certificates. On Windows x64 the PowerShell script installs it without administrator rights. WEIKIO_CLI_VERSION=2026.2.1 in front of either line pins the version.

On macOS the CLI is ready in the Try Weik.io dev container.

Check a download

On a server, sha256sum prints images.env: OK when the file matches its line in SHA256SUMS from the same folder.

Terminal
$ curl -fsSLO https://weik.io/downloads/releases/2026.2.1/images.env
$ curl -fsSLO https://weik.io/downloads/releases/2026.2.1/SHA256SUMS
$ sha256sum -c --ignore-missing SHA256SUMS
You see
images.env: OK

Check the Windows signature

In PowerShell, the status is Valid and the signer certificate is issued to Adafy Oy.

PowerShell
$ Get-AuthenticodeSignature .\weikio-2026.2.1-win-x64.exe | Format-List Status, SignerCertificate
