@kpeters-cbsi - It looks like you are hitting a timeout waiting for the VM to start. Is this a very slow machine by chance? Does this hit 100% of the time or only sometimes?

[kpeters-cbsi]

No, it's a fairly recent machine. Core i7, 16GB RAM. Hits 100% of the time.

@kpeters-cbsi - if you install a new distro (like debian) does this still reproduce?

[kpeters-cbsi]

No; I copied off my VHDX file and tried to "reset" the Ubuntu app; that uninstalled it. When I reinstalled Ubuntu and converted the new installation to WSL2, it started without any problems.

Interesting... I wonder if there was something about your old VHDX that was causing mounting the VHD to take a long time.

[kpeters-cbsi]

The only weirdness I can think of is that I had an SSHFS mount in fstab that I haven't since restored.

[benhillis]

Ah interesting... that could definitely cause issues if your ssh server isn't responding.

@benhillis I had meet the same issue
windows build number: 19035.1000
the ubuntu(wsl2) can not start, the windows crashed when I press the icon.
After I reinstall ubuntu and set version to 2, nothing effect.

NO VMware or VirtualBox, and How can I get the useful log, like lxcore_user.etl etc.

[awson]

Windows build number: 19035.1000
Wsl 2 is slow as hell at startup (but still starts).

(Yesterday I've been stuck in #4731, today I've upgraded to 19035.1, the network issue has been gone, but it's now horrible slow at startup)

[gloveboxes]

yeah, same issue. Take about 40 seconds to start a bash shell (Ubuntu 18.04). It started happening with slow ring build 19035. Noticed if you press ctrl+c it kills whatever is hanging and takes you to the command prompt. Running on the latest Surface Laptop 3, 16GB, i7. I think WSL CPU usage is up too, I noticed my laptop is constantly hot...

[Biswa96]

I'm using WSL with 19035, no issue.

probably related #4738

[gloveboxes]

I uninstalled Ubuntu 18.04 and reinstalled. I worked as expect until I did an apt update/upgrade of the distro and now it's back to the slow start again...

[pds2208]

Same issue and it was on a new build and straight after an apt update/upgrade. Before the apt it was fine.

[ricardosantos9521]

This was happening to me too in Ubuntu, but i remembered the last package that was updated (wslu). I uninstalled it and it works great again (sudo apt autoremove --purge wslu).

Thanks! This fixed it.
