[sibman]

Description:
When attempting to install MicroK8s using Snap on a Linux machine, the installation fails during the install hook with the following error:

bash
Copy code
$ sudo snap install microk8s --classic
error: cannot perform the following tasks:

• Run install hook of "microk8s" snap if present (run hook "install":

---

• source /snap/microk8s/7232/actions/common/utils.sh
  ...
• mkdir -p /var/snap/microk8s/common/run
  /snap/microk8s/7232/actions/common/utils.sh: line 1392: /snap/microk8s/7232/bin/mkdir: cannot execute: required file not found

---

)
Steps to Reproduce:
Run the following command on a Linux machine:
bash
Copy code
sudo snap install microk8s --classic
Observe the error message during installation.
Expected Behavior:
The MicroK8s snap should install successfully without errors.

Actual Behavior:
The installation fails with the following error message:

bash
Copy code
/snap/microk8s/7232/actions/common/utils.sh: line 1392: /snap/microk8s/7232/bin/mkdir: cannot execute: required file not found
Environment:
OS: (Linux Mint 22 (Ubuntu 22.04 LTS))
Snap Version: snap --version 2.65.3+24.04
Snapd Version: snapd --version 2.65.3+24.04
MicroK8s Version: (Attempted with the version from the stable channel)
Shell: (e.g., Bash)
Troubleshooting Steps Tried:
Reinstall Snapd:
bash
Copy code
sudo apt update && sudo apt install --reinstall snapd
Ensure Snapd Services Are Running:
bash
Copy code
sudo systemctl restart snapd
sudo systemctl status snapd
Check Permissions: Verified permissions for /var/snap/microk8s.
Switch to Another Channel: Tried different versions using:
bash
Copy code
sudo snap install microk8s --classic --channel=latest/stable
snap install microk8s --classic --channel=1.31/stable
Possible Cause:
It seems the install hook script is trying to call the mkdir binary from within the MicroK8s snap at /snap/microk8s/7232/bin/mkdir, but this file is either missing or not executable. This might indicate:

A corrupted or incomplete snap package.
A broken link or missing dependency in the snap package.
Request for Assistance:
Could this be a packaging issue with the current MicroK8s release?
Are there any known workarounds to resolve the issue?
Any suggestions on how to manually debug and fix the missing binary issue?

Hi @sibman can you reproduce this on your end? It seems like a snap package corruption but even the revision you requested seems fine:

$ sudo snap install microk8s --classic --revision 7232
microk8s (1.30/stable) v1.30.5 from Canonical✓ installed
