[SOLVED] xrdp daemon failed to start

Installed xrdp AUR package.

Attempted to start the xrdp.service

$ sudo systemctl start xrdp.service
Job for xrdp.service failed because the control process exited with error code.
See "systemctl status xrdp.service" and "journalctl -xeu xrdp.service" for details.

Investigated

$ systemctl status xrdp.service
× xrdp.service - xrdp daemon
     Loaded: loaded (/usr/lib/systemd/system/xrdp.service; disabled; preset: disabled)
     Active: failed (Result: exit-code) since Sun 2023-02-05 11:05:00 CET; 3min 11s ago

So xrdp is already running, but nothing happened when I installed it? Did something go wrong with the installation?

How exactly did you do that? I've just tried using makepkg and it all works as expected so I'm guessing you're using some crappy AUR "helper" that's messed things up for you.

Does the service start if you follow the advice given in the journal excerpt?

Re: [SOLVED] xrdp daemon failed to start

If it only checks for that lock file, probably. But then you might have two instances and the old one operates on the wrong lock.

stat /var/run/xrdp.pid 
cat /var/run/xrdp.pid
ps aux | grep xrdp
find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Re: [SOLVED] xrdp daemon failed to start

Correct @Head_on_a_Stick, I am using Paru. Figured it was better for keeping AUR packages updated simultaneously. You don't approve?

Does the service start if you follow the advice given in the journal excerpt?

There is no /var/run/xrdp.pid file to delete.

I guess I installed it wrong. Perhaps I need to reinstall.

Re: [SOLVED] xrdp daemon failed to start

The PID file should be found at /run/xrdp.pid thanks to the arch-config.diff applied by the package:

I don't approve of most AUR packages so naturally I have a low opinion of any "helpers".

But that's not important here. Have you tried installing the package manually? Does it work then?

Re: [SOLVED] xrdp daemon failed to start

There's an instance running but apparently no /var/run/xrdp.pid ?
What started it? Why is there no lockfile?

I don't know.

I tried killing the living sessions of xrdp and then starting again, but it was no use. Then I tried to enable the service, but it did nothing either. Although now there is an actual output for the following code:

$ stat /var/run/xrdp.pid 
  File: /var/run/xrdp.pid

$ sudo cat /var/run/xrdp.pid
46789

$ sudo ps aux | grep xrdp
root       46787  0.0  0.0  12976   872 ?        S    17:30   0:00 /usr/bin/xrdp-sesman

xrdp.service                             | multi-user.target.wants

Still, nothing worked. So I killed the processes again and checked xrdp status:

Don't copy and paste out of the pager, redirect the ouptut into a file.

Also don't show the status after you actively killed the service process, of course it will just show that the process was killed then.

Re: [SOLVED] xrdp daemon failed to start

Okay I think I just did

sudo systemctl start xrdp

or some variatoin of xrdp, xrdp-service, xrdp.service.

It's active now, so problem solved! Still, when I type `xrdp`, nothing happens. Is that normal at this stage?
