Didn't try on Sid, but on Ubuntu 22.04 the message is clear:

zcobol@TEXAS:~$ runlevel
unknown
zcobol@TEXAS:~$ telinit 5
Couldn't find an alternative telinit implementation to spawn.
zcobol@TEXAS:~$ telinit u
Couldn't find an alternative telinit implementation to spawn.

From the telinit manual:

DESCRIPTION
       telinit may be used to change the SysV system runlevel. Since the concept of SysV runlevels is obsolete the
       runlevel requests will be transparently translated into systemd unit activation requests.

NOTES
       This is a legacy command available for compatibility only. It should not be used anymore, as the concept of
       runlevels is obsolete.

Debian Sid is also an important distribution, so can't leave Debian Sid behind.

[gargle]

I have the same problem. I already upgraded wsl2 to 2.0.14 and am now using 5.15.133.1-microsoft-standard-WSL2. I cannot upgrade libc6. The upgrade is stuck at:

root 515 510 99 07:35 pts/7 00:00:46 telinit u

I'm on windows 10 Enterprise, 21H2, 19044.3324, Windows Feature Experience Pack 1000.19041.1000.0. My debian is trixie/sid.

Starting emac with -nw works but I get a segmentation fault when I start it in X.

[elsaco]

This looks like a sid issue. The stable releases, i.e. bookworm works like the other distros:

elsaco@RIPPER:~$ telinit u
Couldn't find an alternative telinit implementation to spawn.

telinit is just a link to systemctl:

elsaco@RIPPER:~$ ls -l /usr/sbin/telinit
lrwxrwxrwx 1 root root 14 Feb 28  2023 /usr/sbin/telinit -> /bin/systemctl

Sid being Debian Unstable commands might not work properly!

[gargle]

My emacs now works. An export LIBGL_ALWAYS_SOFTWARE=true SOLVES the problem, but I opted for

laenenj@L241362:/mnt/c/git/github-actions$ cat /mnt/c/Users/laenenj/.wslconfig
[wsl2]
swap=0
gpuSupport=false.

[mdboom]

I don't know what causes systemctl to hang when called as telinit, but as a temporary workaround, the following works for me:

Replace /usr/sbin/telinit with the following:

#!/bin/sh
exit 1

chmod it as executable.

[jellopudding]

once using this workaround I ran sudo apt dist-upgrade and then returned original telinit, running telinit u now returns kill() failed: Operation not permitted and no longer hangs

@elsaco do i need to report this case to debian developers?

[Unnil]

I was having the same issue, it seems that telinit wont work if you are not using systemd as your init system.

I tried this https://devblogs.microsoft.com/commandline/systemd-support-is-now-available-in-wsl/

Basically setting this in /etc/wsl.conf
[boot] systemd=true

And it fixed the issue.

thanks bro

[BubblyDevil]

thanks bro. that helped a lot

[Yashparwal1]

This helped me.
https://stackoverflow.com/questions/77781232/apt-stucked-in-setting-up-libc6

I fixed this with sudo mv /usr/sbin/telinit /usr/sbin/telinit.bak and then sudo ln -s /usr/bin/true /usr/sbin/telinit .

[longttjs2210009]

its work for me, thanks a lot

[biovictor]

It also works for me with window10 22H2 and WSL2!

[biovictor]

Awesome thank you very much!!!

[angeldebone]

It works for me, thank you very much!!

[ryd3v]

All I did to fix this issue, was open kali as root in another terminal, ps aux, kill telinit

the upgrade goes through like normal. For those facing this problem in Kali WSL

[Picolin64]

thanks bro

[pedro-santos-web]

Yup this one worked for me, thanks!

[M-ABDULLAH-Aslam]

Thanks, bro. I searched the internet for a long time for a solution. finally found one that works!

[lugo0324]

Worked. Thanks!
