bash: syntax error near unexpected token `<'

This is how to do it after I followed the method, the information above appears

Thank you very much!! I tried this, but it doesn't work!! Thank you for wasting my time!!

😁😁😁😁😁

Maybe you don't know to resolve the issue. I tried the same setup and it is working for me. Better destroy your machine.

THANKS

Thanks.

hey all. I have just noticed these commands were for the times systemd was not fully part of the WSL. it is now truly an integrated part of WSL2 (WSL version 1 would still need this)

Also, Debian distros lack dbus and related packages giving extra errors even with perfect installation. in new true WSL2/systemd way, you will need libpam-systemd (or check what else related is missing) in that case.

We have a long discussion about solving mainly this problem, and in my answers there, I try to summarize solutions whenever possible. microsoft/WSL#8883

obrigado!

Thanks.

Thanks

Thanks

Thanks!!!

It worked! Thanks!

@KhalidMh 's solution above worked for me. thanks!

It works, thanks!

been looking for a fix to this for months. thanks

It is Q3 of 2023, and if you still need this trick, then you can be sure you are doing something wrong.

it still works, thank a lot

Thanks!

Worked well. Thanks!

Very impressive. Thanks for sharing!

Thanks!!!

it worked for me to, just make sure to go the next line after [boot]:

[boot]
systemd=true

It worked! Thank you

The $LOGNAME meaning is the same as whoami command, assigning a value to $LOGNAME if its not existing

it didn't work even with wsl 2

Worked like a charm. I appreciate you! DJ Khaled's voice Now back to trying to figure out how to enable bridge mode between Host + WSL2 + QEMU macOS VM. 🤓

It worked, thanks!

please note that on step 2, you need to write on a DIFFERENT line the systemd=true (and not on the same line than the [boot] part)
