Unable to install AlWSL - Windows Insiders

[tzekid]

I had a working ALWSL installation; tried the three new WSL distros and when then was unable to install ALWSL again.
Extra info: I installed the fast-lane Insiders preview.
No errors shown or any input all.

Is there any helpful info-dump I can provide ?

Sample output:

>.\alwsl.bat remove; .\alwsl.bat install

@tzekid Try to delete C:\Users\[YOUR USERNAME]\AppData\Local\lxss\temp

This issue persists on the latest RTM.

@yobyzal 's comment works.
Delete C:\Users[YOUR USERNAME]\AppData\Local\lxss\temp when stucks in "created 0 fifos".
It may be issues related to wsl.

I have the same problem, the installer is stuck at the same place. @yobyzal The installer cleans the temp folder, nothing to delete.

[ghost]

same issue here. deleting the temp folder does nothing to solve.

I just deleted folder temp twice and then it worked.

[eldon111]

Worked for me too. To hopefully help anyone else like me who didn't pick up on the subtlety right away, you need to delete the temp folder while the installer is stuck.

[yobyzal]

The script keeps on checking if temp exists to make sure that unsquashfs command was finished. But it seems that no command would to delete temp after that.

……
if "%~1" == "install" (
        ……
	call :overwritefs "%~dp0alwsl.sfs"        :: calling `overwritefs`
	call :waitforexit                         :: calling `waitforexit`
	call :transpose
        ……
)

:overwritefs
……
bash -c "cd && cd rootfs-temp && unsquashfs -f -x -d . %~n1.sfs 2>/dev/null"
goto :eof                                         :: just end and no command would to delete `temp` after `unsquashfs` was finished
:waitforexit
if exist "%localappdata%\lxss\temp" (
	goto :waitforexit                         :: <--dead loop
)
goto :eof
……

I suspect that temp was supposed to be removed after unsquashfs ran... Hmmm.

Ran into this issue as well, and my windows explorer was being really weird, couldn't see AppData or lxss folders in the file view; I had to manually enter .../AppData/Local/lxss before I could see the "temp" folder I wanted to delete. Thanks!
