Can't build minikube ISO because of wrong hash

[goto-loop]

What Happened?

Background: I'm trying to set up minikube on my local machine with kvm2 driver and GPU support. It's not working with the binary release, but I saw there are some recent commits to fix GPU issues so I decided to build the binary and ISO files myself, the latter following this guide.

The problem is that after some time, the make out/minikube.iso command outputs the following error message:

2022-05-02 09:32:04 (5.54 MB/s) - ‘/mnt/out/buildroot/output/build/.v1.5.11.tar.gz.ZXc6uR/output’ saved [7494477]

I've downloaded the file manually using both CLI and browser and it always has the same checksum as mentioned in the error, but NOT the expected one.

How can I fix this? Maybe it's possible to change the expected checksum as a workaround?

Attach the log file

No log available since the binary can't be built.

Operating System

Ubuntu

Driver

No response

[goto-loop]

UPDATE: I've had another look at the error message and after the first errors the script tries to download http://sources.buildroot.net/containerd-bin/v1.5.11.tar.gz, which results in an error 404. This is because the directory containerd-bin doesn't exist on the server; however, containerd exists plus it contains a file with the expected hash. I suppose if we changed this URL, the problem would be solved.

That's just the fallback URL

The real problem is upstream

https://github.com/containerd/containerd/archive/refs/tags/v1.5.11.tar.gz

• containerd package has the same tarball checksum problems as others #13193

It would be a good idea to provide a cache for the minikube packages, since those are not available at buildroot.net

config BR2_BACKUP_SITE
        string "Backup download site"
        default "http://sources.buildroot.net"
        help
          Backup site to download from. If this option is set then
          buildroot will fall back to download package sources from here
          if the normal location fails.

Yeah, but... 8dca3b0

It will change again.

Closing as duplicate, just update the hash if it happens to you (again)
