Interesting, I have not seen this. /logs

Hello! Could you please provide more logs to help us better diagnose your issue?

To collect WSL logs, download and execute collect-wsl-logs.ps1 in an administrative powershell prompt:

Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/WSL/master/diagnostics/collect-wsl-logs.ps1" -OutFile collect-wsl-logs.ps1
Set-ExecutionPolicy Bypass -Scope Process -Force
.\collect-wsl-logs.ps1

The scipt will output the path of the log file once done.

Once completed please upload the output files to this Github issue.

Thank you!

On my machine C:\ProgramData\Microsoft\Windows\WindowsApps does not exists.

Here are the logs anyway:: WslLogs-2022-07-05_21-11-28.zip

Same issue here. I attached the log file. WslLogs-2023-01-25_08-09-03.zip

[logularjason]

Same issue. dmesg suggests that the startup delays occur at the lines hv_pci and also hv_balloon. Logs attached.

Same issue here, with a startup time of around 4 minutes. Yesterday it still started in a couple of seconds.

Same issue here. Startup takes more than one minute.

• Windows 11 Version 22H2 (OS Build 22621.1265)
• Windows Terminal Preview Version 1.17.1023
• WSL Version 1.1.3.0

[lister169126]

Same here. Windows 10 21H2 19044.2604 it's happening every start after update wsl. WSL version: WSL: 1.1.3.0 kernel: 5.15.90.1 WSLg: 1.0.49 MSRDC: 1.2.3770 Direct3D: 1.608.2-61064218 DXCore: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp Windows: 10.0.19044.2604

It works fine on previous version Windows/WSL: 10.0.19041.2311

Here's dmesg from old version of wsl and new version. I can send extended logs as above, but it's the same. new_ver.log old_ver.log

[deviantdev]

guys, just use this path to run wsl, remove/reinit the previous links at your system and be happy!

%programfiles%\WindowsApps\MicrosoftCorporationII.WindowsSubsystemForLinux_1.1.6.0_x64__8wekyb3d8bbwe\wsl.exe

What worked for me was to unmap all inaccessible network drives, as in #9358 . Now it takes only a few seconds.

[oomek]

Disconnectting mapped drives is not a solution. I have 6 mostly offline mapped drives and WSL start takes 4 minutes and 17 seconds. This issue also should be reopened.

[mprevot]

A solution would be to be able to set the timeout for network drives, and maybe do a parallel check of drives (I suspect is is sequential).

[mrajweir]

What worked for me was to unmap all inaccessible network drives, as in #9358 . Now it takes only a few seconds.

This was the cause of the delay for me, but as others have said - it's not a solution. Thanks for sharing. How did you even think to check network drives in the first place?

[hoegge]

Is there really no way to troubleshoot this?

[mrajweir]

Is there really no way to troubleshoot this?

It looks like it's been extensively debugged between:

• https://github.com/microsoft/WSL/issues/9358
• https://github.com/microsoft/WSL/issues/10453

Going back to the point - the best thing to do is unmap disconnected drives for now and keep checking those tickets for updates.

[Luuk34]

Still not solved?????? 🤬😁😉

[pedrohgmacedo]

This happens for me as well in WSL1, when automount is set to true in wsl.conf.

[oHervis]

Same issue here. :/

[mrajweir]

Same issue here. :/

Check your network drives and unmap any disconnected ones. They slow WSL on initialization.

[oomek]

Same issue here. :/

Check your network drives and unmap any disconnected ones. They slow WSL on initialization.

Hey Sherlock, the whole point of this issue is not being forced to constantly map and unpap inactive drives.

[JacktheGodzillaSlayer]

Same here, my OS SSD swapped from machine to machine, and ever did many network drive mapping, slow to start wsl as well, also the OS has difficulty to show quick lunch and network item on explorer on the left bar. Last time while I tried to copy a bunch of files from wsl system to usb, it stuck, then I reboot the system now the WSL2 won't even start...

[JacktheGodzillaSlayer]

Try to use the reset options for "Windows Subsystem for Linux" then restart? I resolved the wsl stuck issue by doing this.

[BreizhHardware]

WslLogs-2024-04-01_11-38-42.zip Same issues here, know I cannot start WSL (debian)

[xuefer]

dmsg shows hv_ballon takes 40 seconds

[david-blanchard]

@JacktheGodzillaSlayer, neither removing the Windows Siubsystem for Linux Update or repairing the main app did work for me.

Instead I had to pay attention that all remote units were available (E:, F: G:, etc), because Linux guests try to mount these units too. When they don't find them, it takes a while before the system decide to stop mounting them.

[Kaiser-Yang]

I meet with this, and I figure out that I set auto mount with sshfs in /etc/fstab. And, I reach another network and I forget to set thevpn to access the server, so every time I restart the distro it takes time (must wait the ssh be timed out), I just remove the auto mount, then everything works well. Thanks for your comment giving me inspirations @david-blanchard
