To Reproduce Steps to reproduce the behavior:

1. Open Lens
2. Option "Download kubectl binaries matching the Kubernetes cluster version" enabled with default options.

Kubeconfig: Issue not cause by malformed kubeconfig.

Additional context No additional context.

This issue was caused because there was no write permission on the /Users/kjw/Library/Application Support/Lens/binaries/kubectl/1.24.15 directory. I don't know why that happened (maybe that is the actual bug).

Fixed by chmod +w /Users/kjw/Library/Application Support/Lens/binaries/kubectl/1.24.15.

Same here. Just delete all the folders in /Users/xxx/Library/Application Support/Lens/binaries/kubectl and let Lens download again

[thune-xiaobai]

Same issue. Delete Lens/binaries directory don't help. Seems Lens creates dir with no permissions and have to change it manually.

[m-asfari]

This was off

[philthynz]

Same issue on Windows 10. Just place the kubectl binary under AppData\Roaming\Lens\binaries\kubectl\bundled and it connects.

[straube]

The option mentioned by @m-asfari was already on for me. However, toggling it off and on again fixed the issue.

In Windows 10, you can install WSL using PowerShell with the command wsl --install. After completing the installation, you will need to restart your system, and then WSL should be ready for normal use.
