How to Fix /bin/sh 1 apk not found Error in Linux
If you are trying to create a docker image or run a bash script that uses apk command on Ubuntu, you might encounter an error like this:
bin sh 1 apk not found
/bin/sh: 1: apk: not found
This error means that the shell cannot find the apk command, which is the package manager for Alpine Linux. Alpine Linux is a lightweight and security-oriented Linux distribution that is often used for docker images. However, Ubuntu uses a different package manager called apt, which is incompatible with apk.
In this article, you will learn how to fix this error by installing apk package manager on Ubuntu and how to use it to install packages. You will also learn some tips and tricks for working with apk and apt.
How to Install apk Package Manager on Ubuntu
apk stands for Alpine Package Keeper. It is a simple and fast package manager that uses binary packages with dependency resolution. It is designed for Alpine Linux, but it can also be installed on other Linux distributions, such as Ubuntu.
To install apk on Ubuntu, you can use one of the following methods:
Using apt-get: You can install apk-tools, which is the package that contains the apk command, from the official Ubuntu repositories. To do this, run the following command:
$ sudo apt-get update $ sudo apt-get install apk-tools
Using wget: You can download the latest version of apk-tools from the Alpine Linux website and install it manually. To do this, run the following commands:
$ wget [15]( $ sudo tar -xzf apk-tools-static-2.12.6-r0.apk sbin/apk.static $ sudo mv sbin/apk.static /usr/local/bin/apk $ sudo chmod +x /usr/local/bin/apk
After installing apk, you can verify that it works by running:
$ apk --version apk-tools 2.12.6, compiled for x86_64.
How to Use apk to Install Packages on Ubuntu
To use apk to install packages on Ubuntu, you need to do the following steps:
Update the apk repositories: Before installing any packages, you need to update the list of available packages from the Alpine Linux repositories. To do this, run:
$ sudo apk update fetch [16]( fetch [17]( v3.14.2-38-gf0c5a5c4a9 [18]( v3.14.2-39-gb7f8e7d8f9 [19]( OK: 14949 distinct packages available
Install the packages you need: To install a package using apk, you can use the add subcommand followed by the package name. For example, to install curl, run:
$ sudo apk add curl (1/5) Installing ca-certificates-bundle (20191127-r5) (2/5) Installing nghttp2-libs (1.43.0-r0) (3/5) Installing libcurl (7.79.1-r0) (4/5) Installing curl (7.79.1-r0) (5/5) Installing libgcc (10.3.1_git20210424-r2) Executing busybox-1.33.1-r6.trigger Executing ca-certificates-20191127-r5.trigger OK: 8 MiB in 19 packages
You can also install multiple packages at once by separating them with spaces. For example, to install git and vim, run:
$ sudo apk add git vim (1/12) Installing libacl (2.3.1-r0) (2/12) Installing libattr (2.5.1-r0) (3/12) Installing ncurses-terminfo-base (6.2_p20210612-r0) (4/12) Installing ncurses-libs (6.2_p20210612-r0) (5/12) Installing readline (8.1.0-r0) (6/12) Installing bash (5.1.4-r0) Executing bash-5.1.4-r0.post-install (7/12) Installing brotli-libs (1.0.9-r5) (8/12) Installing nghttp2-libs (1.43.0-r0) (9/12) Installing libcurl (7.79.1-r0) (10/12) Installing expat (2.4.1-r0) (11/12) Installing pcre2 (10.36-r0) (12/12) Installing git (2.32.0-r0) Executing busybox-1.33.1-r6.trigger OK: 32 MiB in 31 packages
Remove or upgrade the packages you don't need: To remove a package using apk, you can use the del subcommand followed by the package name. For example, to remove curl, run:
$ sudo apk del curl WARNING: Ignoring [20]( No such file or directory WARNING: Ignoring [21]( No such file or directory World updated, but the following packages are not removed due to: curl: libcurl OK: 8 MiB in 18 packages
You can also remove multiple packages at once by separating them with spaces.
To upgrade a package using apk, you can use the upgrade subcommand followed by the package name. For example, to upgrade git, run:
$ sudo apk upgrade git WARNING: Ignoring [22]( No such file or directory WARNING: Ignoring [23]( No such file or directory OK: 8 MiB in 18 packages
You can also upgrade all the packages on your system by running sudo apk upgrade without any arguments.
