Steps to reproduce

Expected behavior

clang would be installable.

Last run a few seconds ago: Error: build failed: cannot build base image: The command '/bin/sh -c sudo apt-get -q update && sudo apt-get install -yq libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev clang clang-format gcc make cloc' returned a non-zero code: 100

It will repro even with image section in YAML file.

So even images under the gitpod namespace are affected.

By the way, how did you copy this build output from gitpod?

Can't fill the issue template. But better than not reporting.
Major decline in responsiveness using the Gitpod terminal. Enter a character, say " wait for terminal to update, show it on screen. Same for other characters.

Workaround is to just use a script to enter commands, as much as possible. 😀
Even start and stop workspace suffers.

It is about 1.6 GB to download. Nope 3.1 now.

It is not a permanent degradation, but not shortlived. Maybe it is the size of the workspace, but don't quote me on that.

Nothing on the status page or in the recent issues about this slow-down.

thanks. have a nice day. keep up the great work. 👏

Hi! Thank you for reporting this issue.

Firstly, please note that clang is already installed in every Gitpod workspace. Here are the used installation instructions from Gitpod's default base image:

https://github.com/gitpod-io/workspace-images/blob/9a5a59f7f351bb0d87f084e7374548ca5d53d944/full/Dockerfile#L55-L64

However, maybe it is still version 10 and not 11. Also, maybe there is a temporary bug with apt.llvm.org with the newer version.

I think we should try to update our clang installing lines, so that our Dazzle Docker cache gets invalidated for that layer. This may reveal the same bug in our default image.

[ryanpcmcquen]

@jankeromnes, are there any other redundant packages I have in my Dockerfile?

[ryanpcmcquen]

@ret394, the output is available in the loading window when the container is built.

[jankeromnes]

From the top of my head, at least these are redundant:

clang clang-format clangd gcc make

Our base image buildpack-deps already has most common build tools, and then our Dockerfile has many more tools (ideally every common tool you'd expect in the latest stable version).

[ryanpcmcquen]

@jankeromnes, thanks!

[ryanpcmcquen]

@jankeromnes, I removed clang and now it says clang isn't found:

[ret394]

It can't be copied from the window. Ideally, it would surface a button to copy it or something.

By the way, nice choice for Github bio. More people should do that - hosting on two sites and a useful bio.

@jankeromnes, I removed clang and now it says clang isn't found:

And that's why you don't remove the redundant packages. I had a hunch it would go wrong.

thanks. have a nice day. keep up the great work. 👏

[svenefftinge]

Sorry, about that. It seems that because clang is not explicitly installed there is no alias for clang on the PATH.
Only clang-11 as it was pulled as an upstream dependency. @jankeromnes is that on purpose?

[jankeromnes]

Hm, thay may be a bug with apt.llvm.org (I believe it's supposed to add a clang --> clang-11 alias automatically.)

Will investigate.

[ryanpcmcquen]

@jankeromnes, any news?

[geropl]

@ryanpcmcquen I think it has been solved here: https://github.com/gitpod-io/workspace-images/pull/275#issuecomment-677375553 (but not merged yet)

[jankeromnes]

@ryanpcmcquen The Docker builds on that PR were successfully deployed. Would you be interested in testing the result by temporarily pointing your project to the following Docker image / tag?

Dockerfile:

FROM gitpod/workspace-full:branch-jx-explicitly-install-clang

Or, .gitpod.yml:

image: gitpod/workspace-full:branch-jx-explicitly-install-clang

Hopefully this will fix the clang installation. If you're not able to or interested in testing it, I'll test it next week and merge the PR then.

Thanks again for reporting this problem. 👍

[ryanpcmcquen]

Of course, I would be honored to test it, I'll report back as soon as I do.

[ryanpcmcquen]

@jankeromnes, it works!!!! Woo.

[ryanpcmcquen]

@jankeromnes, will this change also populate to workspace-full-vnc?

[ryanpcmcquen]

This is fixed!
https://github.com/ryanpcmcquen/basque/commit/60daeae673d4f6f57b15c6bd5edbce028ef00a5e

[jankeromnes]

it works!!!! Woo.

That's awesome, many thanks for confirming!

will this change also populate to workspace-full-vnc?

Yes, should already have, as full-vnc is based on full.
