Can't run pachctl on WSL2

[Persedes]

What happened?:

Following the local pachyderm instructions (running on WSL2 / 20.04):

• Install homebrew and run the Next steps
  • tested everything works via brew install hello
• install pachctl via brew tap pachyderm/tap && brew install pachyderm/tap/pachctl@2.4

Trying to run pachctl, gives the following message:

pachctl
zsh: permission denied: pachctl

# same when running it via bash:
/bin/bash pachctl
/home/linuxbrew/.linuxbrew/bin/pachctl: /home/linuxbrew/.linuxbrew/bin/pachctl: cannot execute binary file

What you expected to happen?:

Not get the permission denied: pachctl message.

How to reproduce it (as minimally and precisely as possible)?:

# run the next steps as recommended from the following command too
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

brew tap pachyderm/tap && brew install pachyderm/tap/pachctl@2.4
pachctl

Anything else we need to know?:
Installing other packages via brew seems to work, so I don't think its a homebrew issue. (E.g. I can finish the local deploy guide, including the helm install via brew)

Environment?:

• Kubernetes version (use kubectl version):
• Pachyderm CLI and pachd server version (use pachctl version):
• Cloud provider (e.g. aws, azure, gke) or local deployment (e.g. minikube vs dockerized k8s):
• If you deployed with helm, the values you used (helm get values pachyderm):
• OS (e.g. from /etc/os-release):
• Others:

This is on WSL2 .

The permissions for linuxbrew look allright:

ls -lhA /home/linuxbrew/.linuxbrew/bin/pachctl
lrwxrwxrwx 1 mheiser mheiser 40 Dec 27 09:14 /home/linuxbrew/.linuxbrew/bin/pachctl -> ../Cellar/pachctl@2.4/v2.4.2/bin/pachctl

Turns out the Cellar permissions were off, so I tried to fix them:

Try to install pachctl@2.3 and see if that works. Random thought, do you have an x86 or ARM CPU?

ah, I think this is the problem:

==> Downloading https://github.com/pachyderm/pachyderm/releases/download/v2.3.9/pachctl_2.3.9_darwin_amd64.zip

Homebrew chose the darwin_amd64
If I use the amd_64.targ.gz from https://github.com/pachyderm/pachyderm/releases it works.
Maybe something in homebrew is getting confused which one to choose?

[BOsterbuhr]

Ah yes this is an issue we just identified before our winter break. I will keep this issue open and will talk with the team in the new year and update this when we have a fix. Sorry for the inconvenience.

[Persedes]

All good, in case others find it helpful, here's a fix for 2.4

wget https://github.com/pachyderm/pachyderm/releases/download/v2.4.2/pachctl_2.4.2_linux_amd64.tar.gz
tar -xf pachctl_2.4.2_linux_amd64.tar.gz 

# change permissions, so we can delete the old file (sudo rm should work too)
chmod 777 /home/linuxbrew/.linuxbrew/Cellar/pachctl@2.4/v2.4.2/bin/pachctl

# install the new one
cp pachctl_2.4.2_linux_amd64/pachctl /home/linuxbrew/.linuxbrew/Cellar/pachctl@2.4/v2.4.2/bin/
# fix permissions
chmod 555 /home/linuxbrew/.linuxbrew/Cellar/pachctl@2.4/v2.4.2/bin/pachctl
# confirm everything works
pachctl
