Error Invalid Pkgver '3.x.x' in Apkbuild: How to Fix It
If you are trying to build a package for Alpine Linux or postmarketOS using apkbuild, you may encounter an error like this:
ERROR: Invalid pkgver '3.x.x' in APKBUILD: /path/to/APKBUILD
This error means that the pkgver variable in your apkbuild file is not valid. The pkgver variable specifies the version of the software that you are packaging, and it should match the version released by the upstream author. It can contain letters, numbers, periods and underscores, but not a hyphen.

In this article, we will explain what causes this error and how to fix it. We will also provide some tips and resources for creating apkbuild files and building packages for Alpine Linux or postmarketOS.
What is Apkbuild and What is Pkgver
Apkbuild is a shell script that contains the build information required by Alpine Linux or postmarketOS packages. It defines various variables and functions that tell abuild or pmbootstrap how to download, extract, compile, install and package the software. You can find more details about apkbuild in the guide.
Pkgver is one of the mandatory variables that you need to define in your apkbuild file. It indicates the version of the software that you are packaging, and it should be the same as the version published by the author of the upstream software. For example, if you are packaging foobar-2.7.1.tar.gz, you should use pkgver=foobar.
What is the Error Invalid Pkgver '3.x.x' in Apkbuild and Why It Occurs
The error invalid pkgver '3.x.x' in apkbuild occurs when you use a placeholder value for the pkgver variable instead of a valid version number. This usually happens when you create a new apkbuild file from a template or copy an existing one from another package. The template or the copied file may have a placeholder value like '3.x.x' or '0_git' for the pkgver variable, which you need to replace with the actual version number of your package.
If you don't replace the placeholder value, abuild or pmbootstrap will complain that your pkgver variable is not valid and refuse to build your package. This is because they need to know the exact version number of your package for various reasons, such as generating checksums, creating source tarballs, comparing versions for updates, etc.
How to Fix the Error
To fix the error invalid pkgver '3.x.x' in apkbuild, you need to do two things:
Find the correct pkgver for your package
Edit your apkbuild file and replace the placeholder value with the correct pkgver
Let's see how to do these steps in more detail.
Find the Correct Pkgver for Your Package
The first step is to find out what is the correct version number of your package. This depends on where you get your source code from. There are two common scenarios:
You get your source code from an official release tarball or archive (e.g., foobar-2.7.1.tar.gz)
You get your source code from a version control system (e.g , git, svn, etc.) and you want to use the latest commit or revision
If you get your source code from an official release tarball or archive, you can simply use the version number that is part of the file name. For example, if you download foobar-2.7.1.tar.gz from the upstream website, you can use pkgver=2.7.1 in your apkbuild file.
If you get your source code from a version control system, you need to use a different method to determine the pkgver. You can either use a fixed tag or branch name that corresponds to a specific release (e.g., v2.7.1 or 2.7.x), or you can use a dynamic value that reflects the latest commit or revision in the repository (e.g., r1234 or 1a2b3c4d). The latter option requires you to write a custom pkgver() function in your apkbuild file that will update the pkgver variable automatically when you run abuild or pmbootstrap.
The pkgver() function is a shell script that runs after the sources are fetched, extracted and prepare() executed. It should output the new package version to the standard output, and it can use any files or commands available in the source directory. For example, if you are using git as your version control system, you can use something like this:
pkgver() cd $ pkgname printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
This will generate a pkgver like r1234.1a2b3c4d, where 1234 is the number of commits and 1a2b3c4d is the abbreviated hash of the latest commit. You can use other commands or formats as long as they produce a valid and meaningful pkgver.
For more information on how to write a pkgver() function for different version control systems, see the manual page.
Edit Your Apkbuild File and Replace the Placeholder Value with the Correct Pkgver
The second step is to edit your apkbuild file and replace the placeholder value for the pkgver variable with the correct one that you found or generated in the previous step. You can use any text editor of your choice, such as nano, vim, emacs, etc.
For example, if your apkbuild file looks like this:
pkgname=foobar pkgver=3.x.x pkgrel=0 ...
You should change it to something like this:
pkgname=foobar pkgver=2.7.1 pkgrel=0 ...
Or this:
pkgname=foobar pkgrel=0 ... pkgver() cd $ pkgname printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
After editing your apkbuild file, save it and exit your editor.
Conclusion
In this article, we have learned how to fix the error invalid pkgver '3.x.x' in apkbuild. We have seen that this error occurs when we use a placeholder value for the pkgver variable instead of a valid version number of our package. We have also learned how to find or generate the correct pkgver for our package depending on where we get our source code from, and how to edit our apkbuild file and replace the placeholder value with the correct one.

FAQs
What is a split package and how to create one?
A split package is a way of creating multiple packages from a single apkbuild file. This is useful when you want to split a large software into smaller components that can be installed separately or depend on each other. For example, you can create a split package for python that contains python-base, python-docs, python-tests, etc.
To create a split package, you need to define an array of subpackages in your apkbuild file, and use a subpackage() function for each subpackage to define its name, description, dependencies, install script, etc. For example, you can use something like this:
pkgname=python pkgver=3.9.7 pkgrel=0 ... subpackages="$pkgname-base $pkgname-docs $pkgname-tests" ... python-base() pkgdesc="Python base package" depends="" install_if="$pkgname=$pkgver-r$pkgrel" ... python-docs() pkgdesc="Python documentation" depends="$pkgname-base" ... python-tests() pkgdesc="Python test suite" depends="$pkgname-base" ...
For more information on how to create a split package, see the guide.
How to use pkgver() function to automatically update the pkgver?
The pkgver() function is a way of updating the pkgver variable automatically when you run abuild or pmbootstrap. This is useful when you get your source code from a version control system and you want to use a dynamic value that reflects the latest commit or revision in the repository. For example, you can use something like this:
pkgver() cd $ pkgname printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
This will generate a pkgver like r1234.1a2b3c4d, where 1234 is the number of commits and 1a2b3c4d is the abbreviated hash of the latest commit. You can use other commands or formats as long as they produce a valid and meaningful pkgver.
The pkgver() function runs after the sources are fetched, extracted and prepare() executed. It should output the new package version to the standard output, and it can use any files or commands available in the source directory. For example, if you are using svn as your version control system, you can use something like this:
pkgver() cd $ pkgname printf "r%s" "$(svnversion)"
This will generate a pkgver like r1234, where 1234 is the revision number of the working copy.
For more information on how to use a pkgver() function for different version control systems, see the manual page.
How to check for common packaging mistakes with namcap?
Namcap is a tool that analyzes apkbuild files and packages for common packaging mistakes. It can help you find errors or warnings such as missing dependencies, unused variables, incorrect permissions, etc. It can also provide suggestions or tips for improving your package quality.
To use namcap, you need to install it from the community repository with apk add namcap. Then you can run it on your apkbuild file or your package file with namcap /path/to/APKBUILD or namcap /path/to/pkgname-pkgver.apk. You will see a report of errors, warnings and notices that namcap found in your file.
For example, if you run namcap on an apkbuild file that has an invalid pkgver variable, you will see something like this:
$ namcap /path/to/APKBUILD APKBUILD (foobar) E: Invalid pkgver '3.x.x'
This means that your apkbuild file has an error (E) with the pkgver variable that has an invalid value '3.x.x'. You should fix this error by using a valid version number for your package.
For more information on how to use namcap and what it can check for, see the manual page.
How to use python-pkgbuild-language-server for editing apkbuild files?
Python-pkgbuild-language-server is a tool that provides language support for editing apkbuild files in various editors or IDEs. It can help you with syntax highlighting, code completion, linting, formatting, etc. It can also integrate with namcap and other tools to provide additional features.
To use python-pkgbuild-language-server, you need to install it from PyPI with pip install python -pkgbuild-language-server. Then you need to configure your editor or IDE to use it as a language server for apkbuild files. You can find instructions for different editors or IDEs on the of the project.
For example, if you are using Visual Studio Code, you can install the from the marketplace, which will automatically use python-pkgbuild-language-server as the language server for apkbuild files. You can also customize the settings of the extension to enable or disable certain features, such as namcap integration, auto-formatting, etc.
