Rancher Desktop 1.19.3 - darwin (aarch64) not working on M1 Mac Sequoia 15.5

[ocofaigh]

Actual Behavior

Rancher was working fine before I updated to Sequoia, but now I get this on launch:

 '0:/tmp/rd-nginx.conf-PY15y1.nginx.conf'
  ],
  stdout: '',
  stderr: '/usr/bin/scp: write remote "/tmp/rd-nginx.conf-PY15y1.nginx.conf": Failure\r\n' +

I only really need to use docker, not kubernetes, but the image manager never comes up:

Hi! Would you be able to attach your logs to the issue so we can look at it? Ideally enable debug logging before quitting Rancher Desktop and restarting it, so that we get extra logging that might be relevant. Thanks!

I managed to fix this by deleting rm -rf "/Users/$USER/Library/Application Support/rancher-desktop/lima/0" and re-launching RD

[mook-as]

FWIW, the log says:

qemu-img: Could not open '/Users/conall/Library/Application Support/rancher-desktop/lima/0/diffdisk': Failed to get shared "write" lock

So rebooting probably would have worked too. Though it sounds like this probably happened after switching from qemu to vz?

Use the commands written below one by one.

/Applications/Rancher\ Desktop.app/Contents/Resources/resources/darwin/bin/rdctl shutdown
mkdir -p ~/.rd/
ls -l ~/Library/Application\ Support/rancher-desktop/lima
mv ~/Library/Application\ Support/rancher-desktop/lima ~/.rd/
ls -l ~/.rd/
ln -s ~/.rd/lima ~/Library/Application\ Support/rancher-desktop/lima
ls -l ~/Library/Application\ Support/rancher-desktop/

Use the commands written below one by one.

This is just moving the Lima directory to a different location. This is only needed when the username is too long, so the socket names in the original location don't work.

I don't know why this would help with resolving the write lock issue, except accidentally.
