Could not find 'bsdtar' on $PATH.

I have this workflow right here, basically taken from the example in the docs:

name: C/C++ AppImage

on:
  push:
    branches:
    - master
  pull_request:
    branches: 
    - master

jobs:
  build-appimage:

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - name: install dependencies
        run: |
          sudo apt-get update
          sudo apt-get install -y qt5-default qtdeclarative5-dev cmake libarchive-tools 
      - name: configure
        run: qmake
      - name: build
        run: make
      - name: create directory
        run: mkdir -p AppDir/usr/bin
      - name: copy binary
        run: mv selectdefaultapplication AppDir/usr/bin/
      - name: Build AppImage
        uses: AppImageCrafters/build-appimage@v1
        env:
          UPDATE_INFO: gh-releases-zsync|magnus-ISU|selectdefaultapplication|latest|*x86_64.AppImage.zsync
        with:
          recipe: AppImageBuilder.yml
      - uses: actions/upload-artifact@v2
        with:
          name: AppImage

I got this error output at the "Build AppImage" step:

I believe that bsdtar should be part of libarchive-tools on Ubuntu 20.04(latest version used by GitHub Actions); if so, why is that?

AppImageCrafters / build-appimage

Could not find 'bsdtar' on $PATH. #6
