Is there a reason you didn't include this for RPM?

Yeah. Seems like RPM clients download the keyring file and then install it as an RPM package. The original .asc file should be somewhere on the disk, but the source of truth is rpm -qi query.
Nevermind, misread/confused. Yeah, I actually can do a curl/wget and then run gpg on it. Will add now.

Now added for both, but I changed my mind a bit. Instead of verifying the downloaded/installed keyring, now we verify the keyrings to be downloaded (via curl | gpg). It's actually more realistic for users who want to check the fingerprints first.

This MR contains the following updates: | Package | Update | Change | |---|---|---| | [cli/cli](https://github.com/cli/cli) | minor | `v2.89.0` → `v2.90.0` | MR created with the help of [el-capitano/tools/renovate-bot](https://gitlab.com/el-capitano/tools/renovate-bot). **Proposed changes to behavior should be submitted there as MRs.** --- ### Release Notes <details> <summary>cli/cli (cli/cli)</summary> ### [`v2.90.0`](https://github.com/cli/cli/releases/tag/v2.90.0): GitHub CLI 2.90.0 [Compare Source](cli/cli@v2.89.0...v2.90.0) #### Manage agent skills with `gh skill` (Public Preview) [Agent skills](https://agentskills.io) are portable sets of instructions, scripts, and resources that teach AI coding agents how to perform specific tasks. The new `gh skill` command makes it easy to discover, install, manage, and publish agent skills from GitHub repositories - right from the CLI. ``` # Discover skills gh skill search copilot # Preview a skill without installing gh skill preview github/awesome-copilot documentation-writer # Install a skill gh skill install github/awesome-copilot documentation-writer # Pin to a specific version gh skill install github/awesome-copilot documentation-writer --pin v1.2.0 # Check installed skills for updates gh skill update --all # Validate and publish your own skills gh skill publish --dry-run ``` Skills are automatically installed to the correct directory for your agent host. `gh skill` supports GitHub Copilot, Claude Code, Cursor, Codex, Gemini CLI, and Antigravity. Target a specific agent and scope with `--agent` and `--scope` flags. `gh skill publish` validates skills against the [Agent Skills specification](https://agentskills.io/specification) and checks remote settings like tag protection and immutable releases to improve supply chain security. Read the full announcement on the [GitHub Blog](https://github.blog/changelog/2026-04-16-manage-agent-skills-with-github-cli/). `gh skill` is launching in public preview and is subject to change without notice. #### Official extension suggestions When you run a command that matches a known official extension that isn't installed (e.g. `gh stack`), the CLI now offers to install it instead of showing a generic "unknown command" error. This feature is available for [github/gh-aw](https://github.com/github/gh-aw) and [github/gh-stack](https://github.com/github/gh-stack). When possible, you'll be prompted to install immediately. When prompting isn't possible, the CLI prints the `gh extension install` command to run. #### `gh extension install` no longer requires authentication `gh extension install` previously required a valid auth token even though it only needs to download a public release asset. The auth check has been removed, so you can install extensions without being logged in. #### What's Changed ##### ✨ Features - Add `gh skill` command group: install, preview, search, update, publish by [@​SamMorrowDrums](https://github.com/SamMorrowDrums) in [#​13165](cli/cli#13165) -
