+title: 'Alt Package Registry'
+license: 'Apache-2.0'
+origin_url: 'https://codeberg.org/forgejo/docs/src/commit/8f46649aa9864b075c136c3a1eb86dc1d3579829/docs/user/packages/rpm.md'
+---
+
+Publish [Alt](https://www.altlinux.org/APT_в_ALT_Linux/CreateRepository) packages for your user or organization.
+
+## Requirements
+
+To work with the Alt registry, you need to use the APT-RPM package manager to consume packages.
+
+The following examples use `apt-rpm`.
+
+## Configuring the package registry
+
+To register the RPM registry add the url to the list of known sources to the config file in the `/etc/apt/sources.list.d/` directory:
+
+```shell
+rpm https://forgejo.example.com/api/packages/{owner}/alt/{group}.repo {arch} classic
+```
+
+| Placeholder | Description                                                        |
+| ----------- | ------------------------------------------------------------------ |
+| `owner`     | The owner of the package.                                          |
+| `group`     | Optional: Everything, e.g. empty, `el7`, `rocky/el9`, `test/fc38`. |
+| `arch`      | Architecture.                                                      |
+
+Example:
+
+```shell
+# without a group and architecture x86_64
+rpm https://forgejo.example.com/api/packages/testuser/alt/alt.repo x86_64 classic
+
+# with the group 'centos/el7' and architectire noarch
+rpm https://forgejo.example.com/api/packages/testuser/alt/group/example1.repo noarch classic
+```
+
+If the registry is private, provide credentials in the url. You can use a password or a personal access token:
+
+```shell
+rpm https://{username}:{your_password_or_token}@forgejo.example.com/api/packages/{owner}/alt/{group}.repo {arch} classic
+```
+
+You have to add the credentials to the urls in the created `.repo` file in `/etc/apt/sources.list.d/` too.
+
+## Publish a package
+
+To publish a RPM package (`*.rpm`), perform a HTTP PUT operation with the package content in the request body.
+
+```http
+PUT https://forgejo.example.com/api/packages/{owner}/alt/{group}/upload
+```
+
+| Parameter | Description                                                        |
+| --------- | ------------------------------------------------------------------ |
+| `owner`   | The owner of the package.                                          |
+| `group`   | Optional: Everything, e.g. empty, `el7`, `rocky/el9`, `test/fc38`. |
+
+Example request using HTTP Basic authentication:
+
+```shell
+# without a group
+curl --user your_username:your_password_or_token \
+     --upload-file path/to/file.rpm \
+     https://forgejo.example.com/api/packages/testuser/alt/upload
+# with the group 'group/example1'
+curl --user your_username:your_password_or_token \
+     --upload-file path/to/file.rpm \
+     https://forgejo.example.com/api/packages/testuser/alt/group/example1/upload
+```
+
+If you are using 2FA or OAuth use a personal access token instead of the password.
+You cannot publish a file with the same name twice to a package. You must delete the existing package version first.
+
+The server responds with the following HTTP Status codes.
+
+| HTTP Status Code  | Meaning                                                                              |
+| ----------------- | ------------------------------------------------------------------------------------ |
+| `201 Created`     | The package has been published.                                                      |
+| `400 Bad Request` | The package is invalid.                                                              |
+| `409 Conflict`    | A package file with the same combination of parameters exist already in the package. |
+
+## Delete a package
+
+To delete a RPM package perform a HTTP DELETE operation. This will delete the package version too if there is no file left.
+
+```http
+DELETE https://forgejo.example.com/api/packages/{owner}/alt/{group}.repo/{architecture}/RPMS.classic/{package_file_name.rpm}
+```
+
+| Parameter               | Description                  |
+| ----------------------- | ---------------------------- |
+| `owner`                 | The owner of the package.    |
+| `group`                 | Optional: The package group. |
+| `package_file_name.rpm` | The package file name.       |
+| `architecture`          | The package architecture.    |
+
+Example request using HTTP Basic authentication:
+
+```shell
+# without a group
+curl --user your_username:your_token_or_password -X DELETE \
+     https://forgejo.example.com/api/packages/testuser/alt/alt.repo/x86_64/RPMS.classic/test-package.rpm
+
+# with the group 'group/example1'
+curl --user your_username:your_token_or_password -X DELETE \
+     https://forgejo.example.com/api/packages/testuser/alt/group/example1.repo/x86_64/RPMS.classic/test-package.rpm
+```
+
+The server responds with the following HTTP Status codes.
+
+| HTTP Status Code | Meaning                            |
+| ---------------- | ---------------------------------- |
+| `204 No Content` | Success                            |
+| `404 Not Found`  | The package or file was not found. |
+
+## Install a package
+
+To install a package from the RPM registry, execute the following commands:
+
+```shell
+# use latest version
+apt-get install {package_name}
+# use specific version
+apt-get install {package_name}-{package_version}
+```
