/usr/local/bin/bundle disappeared from the latest ubuntu-20.04 image

[anthonyfok]

Description
/usr/local/bin/bundle (and /usr/local/bin/bundler) was in ubuntu-20.04 image version 20210419.1, but no longer found in version 20210606.1.

GitHub Actions such as limjh16/jekyll-action-ts which relies on bundle now fails with the error:

Error: Unable to locate executable file: bundle. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.

See limjh16/jekyll-action-ts#18 and OpenDRR/documentation#13 for more details.

Image version

Image version where you are experiencing the issue.
20210606.1

Expected behavior
/usr/local/bin/bundle is available like in image version 20210419.1

Actual behavior
/usr/local/bin/bundle is not available.

bundle is still available in other paths or in other names elsewhere on the system, but not as bundle in the system PATH:

Repro steps
See the GitHub workflow run at https://github.com/OpenDRR/documentation/actions/runs/926023494

(In latest run, I have worked around the issue with sudo apt update && sudo apt install ruby-bundler.)

Final thoughts
I suspect the disappearance of /usr/local/bin/bundle was unintended, and I wasn't able to find any commit that explicitly removed it from the Ubuntu runners. (I did find its removal from Windows, but that's not related to this bug.)

Admittedly, while "Bundler version 2.1.4" is listed under "Package Management" in images/macos/macos-10.15-Readme.md, Bundler was apparently never listed in images/linux/Ubuntu2004-README.md or alike.

Regardless whether you want to have /usr/local/bin/bundle available or not, I guess a bit more clarification on this would be helpful so that GitHub Actions developers can know whether to rely on bundle being available or not.

Many thanks!

Hello, @anthonyfok.
Thank you for your report. We will take a look.

@anthonyfok,
It is recommended to use official Ruby action to make sure that your build uses specific Ruby version: https://github.com/ruby/setup-ruby, Official Ruby binaries will be installed on images by default.

Hello @anthonyfok. I'm going to close this issue since it is not image related. As @al-cheb mentioned, we recommend you to use https://github.com/ruby/setup-ruby action and install bundler in runtime. In case of any questions feel free to contact us. Thank you.
