Segfault in helm-wrapper

[alexanderjohn]

I followed the manual installation instructions and was able to install 3.7.1 and 2.16.1

When I run helm, Incorrect helm commands execute with no issue:

$ helm blahblah
Error: unknown command "blahblah" for "helm"
Run 'helm --help' for usage.

However, every 'successful' command ends with the following:

$ helm
The Kubernetes package manager
# ...
# ...
# ...
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x4aad4f]

Could you please add the output of the command helm version?

Sorry too hear it. Could you please pass the next information:

• Output of helmenv version
• OS
• Arch

[g4mjamesc]

HI

 helmenv version
Error: unknown command "version" for "helmenv"
Run 'helmenv --help' for usage.
unknown command "version" for "helmenv"

helmenv -h
Helm version manager

Flags:
  -h, --help   help for helmenv

Ubuntu 22.04 x86_64

[alexppg]

If helmenv doesn't have the version parameter, it should mean that you're not using the latest version. Could you please upgrade?

HI

i think the problem is the readme is out of date. I am personally guilty of copying/pasting without reading.

wget https://github.com/little-angry-clouds/kubernetes-binaries-managers/releases/download/0.0.4/helmenv-linux-amd64.tar.gz
tar xzf helmenv-linux-amd64.tar.gz
mv helmenv-linux-amd64 ~/.bin/helmenv
mv helm-wrapper-linux-amd64 ~/.bin/helm

if i download a later version e.g 1.0.0 the files are completely different., i get the below 3 binaries, instead of a helmenv-linux-amd64 and a helm-wrapper-linux-amd64, so the instructions are abit out of date. Im assuming these 3 binaries still go into ~./bin./* but not sure

helm-linux-amd64
kubectl-linux-amd64 oc-linux-amd64

[alexppg]

That makes sense, I changed the way of the binaries are compressed and I forgot to update the READMEs.

The binaries are now all packaged in a combination of OS and ARCH, but it has both the wrapper and the binary manager. So you'll have to move both helmenv and helm-wrapper (possibly changing the name helm-wrapper for helm for convenience) to your PATH and that should be it.

This is how it's now packaged:

wget https://github.com/little-angry-clouds/kubernetes-binaries-managers/releases/download/v1.0.0/kubernetes-binaries-managers_1.0.0_linux_amd64.tar.gz
unp kubernetes-binaries-managers_1.0.0_linux_amd64.tar.gz

just to let you know, this worked.

[alexppg]

Awesome. I'll close this issue when I update the README.

[alexppg]

Done.
