Lima uses 
lima
as the internal username when the host username is not valid on Linux. This is not an issue and works fine.
The problem here is the space in the username, which seems to be a problem when passing a filename to 
ssh
, even though the filename is quoted. No, that isn't the issue either; it may be a problem with the allowed keys.

Is there a way to regenerate the keys used in 
/Users/wenmingcao 1/Library/Application Support/rancher-desktop/lima/_config/user

There should be no need to regenerate it; I suspect it isn't setup correctly inside the VM. I'm just trying to figure out how to best debug this. Do you have 
socat
installed on the machine? Or can you install it with 
brew install socat
?

Ok, thanks! So you can get a root shell like this: 
$ cd ~/Library/Application\ Support/rancher-desktop/lima/0/
$ socat -,echo=0,icanon=0 unix-connect:serial.sock
root
Welcome to Alpine!

[...]
lima-rancher-desktop:~#
There will be no prompt after running 
socat
, but it is waiting for a username, so you have to type 
root
and Enter
Then check if the 
authorized_keys
file exists (but use 
lima.linux
instead of 
jan.linux
): 
lima-rancher-desktop:~# ls -la /home/jan.linux/.ssh
total 12
drwx------    2 jan      jan           4096 Jun 29 00:36 .
drwxr-xr-x    4 jan      jan           4096 Jun 29 16:48 ..
-rw-------    1 jan      jan             92 Jun 29 00:36 authorized_keys
Let me know if the file exists (and is non-empty)

Thank you. I will report back after I get socat installed and checked the keys for the lima user

The content of 
authorized_keys
should be identical to the 
user.pub
file on the host
lima-rancher-desktop:~# cat /home/jan.linux/.ssh/authorized_keys
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILqESOec8Hf8PFT7Ptz6z9NexbzCsARBXCV6yUNibreG jan@mactop
$ cat ~/Library/Application\ Support/rancher-desktop/lima/_config/user.pub

I got socat installed and there is no lima user in the home dir

Can you run 
cat /var/log/lima-init.log
and create a text snippet to attach it here?
It should look like this: 
lima-rancher-desktop:~# cat /var/log/lima-init.log
+ export 'LIMA_CIDATA_MNT=/mnt/lima-cidata'
+ '[' --local '!=' --local ]
+ ln -s /var/log/lima-init.log /var/log/cloud-init-output.log
+ LIMA_CIDATA_DEV=/dev/disk/by-label/cidata
+ mkdir -p -m 700 /mnt/lima-cidata
+ mount -o 'ro,mode=0700,dmode=0700,overriderockperm,exec,uid=0' /dev/disk/by-label/cidata /mnt/lima-cidata
+ . /mnt/lima-cidata/lima.env
[...]
There should be a section when the user is created; see if there are any errors around there: 
+ hostname lima-0
+ LIMA_CIDATA_HOMEDIR=/home/jan.linux
+ useradd --home-dir /home/jan.linux --create-home --uid 501 jan
+ echo 'jan ALL=(ALL) NOPASSWD:ALL'
+ LIMA_CIDATA_SSHDIR=/home/jan.linux/.ssh
+ mkdir -p -m 700 /home/jan.linux/.ssh
+ awk '/ssh-authorized-keys/ {flag=1; next} /^ *$/ {flag=0} flag {sub(/^ +- /, ""); gsub("\"", ""); print $0}' /mnt/lima-cidata/user-data
+ id -g jan
+ LIMA_CIDATA_GID=1000
+ chown -R 501:1000 /home/jan.linux/.ssh
+ chmod 600 /home/jan.linux/.ssh/authorized_keys

I see the problem; it is the mountpoint of the user directory containing a space that is throwing an error earlier, so the whole rest of the init script is skipped 😞
This will need to be fixed in Lima itself.

Ah and the space is not escaped. A workaround would be to rename that path to not have a space?

I'm not sure if there is a workaround; I'll let you know if I think of something

So I tried to work around this problem by creating a symlink to the user directory without a space, and using that as the 
HOME
directory, but that didn't work properly either. So I'm out of ideas for now, beyond creating another username without a space in it, which is a bit drastic.
I'll try to fix this in Lima, so it should work correctly in the next release.

Ok thank you for your efforts. Would this be in the next release of rancher-desktop or of lima?

fast-garage-66093

First it has to be fixed in Lima, and then Rancher Desktop will import Lima (it doesn't have to be a release, but should at least be merged to 
master
)
Once it is in Lima, it will be possible to change the version embedded in Rancher Desktop, but that is not really a supported scenario. But I can describe what to do, if that is something you want to try instead of waiting for the official release (which will not happen until the end of July or so).
I've created Mountpoints cannot include whitespace · Issue #933 · lima-vm/lima for the Lima issue, but it turns out to be more effort than a quick fix because parts need to changed in yet another repo, so I'll leave this for another day.

I've been on vacation most of August and just came back on Friday. It looks like nobody else has fixed this, so it is still on my (by now quite huge) todo pile...

Sorry, it somehow got bumped off my radar 😞 and looks like nobody else has picked it up either. Will try to take another look
