The situation

Here is a long existing non standard manjaro-system using sway. I switch on the auto update on shut down in pamac-gtk.
I installed plymouth an activated the hook in /etc/mkinitcpio.conf and the splash screen in grub.
At shutdown plymouth shows a grafical screen with update but it don’t work.

Conclusion

Can someone help me?

Thank you

Try systemctl start --now pamac-offline-upgrade

–now saves the command, oh and systemctl understands service so not needed

??

--now is a modifier for enable, disable, or mask.
It will start or stop the service respective to and in addition to those.

Your version, if functional, would be roughly equal to systemctl start start.

Thanks for trying

It seems not to be a problem of systemctl.
Using pacman in pamac-offline-upgrade.service works:
ExecStart=/usr/bin/pacman -Suu --noconfirm

# journalctl | grep pamac
Nov 23 07:41:03 PC systemd[1]: pamac-offline-upgrade.service: Deactivated successfully.

I could be satisfied but after the next pamac update it will use pamac again.

I think pamac misses a service which works on multi-user.target but not in shutdown.target. So I need a better debug level for pamac.

Package updates on shutdown are currently broken: Issues · Applications / pamac · GitLab

Thanks

I left a link in It can't upgrade the system at shutdown, if plymouth is not installed. (#1387) · Issues · Applications / pamac · GitLab

Well, if pacman works, you could use a drop in:

systemctl edit pamac-offline-upgrade.service

Or create your own pacman version.

That’s what I did. It worked until a reinstall of pamac.

That’s an idea …

My Solution

I had to uncheck autoupdates in pamac manager.

So I created a cronjob /etc/cron.daily/autoupdate:

#!/bin/bash

/usr/bin/pamac checkupdates
if [ $? -eq 100 ]; then 
    /usr/bin/touch /var/autoupdate/system-update
  # pacman needs to update its database
  # pamac only updates its own  
  # /usr/bin/pamac upgrade -w --no-confirm
  /usr/bin/pacman -Syyuuw --noconfirm  
fi

I created a directory /var/autoupdate/ because the cronjob has not enough permissions to root directory and temporary directories are umounted when update works.

Changing permissions:

chmod 1777 /var/autoupdate

Then I copied /usr/lib/systemd/system/pamac-offline-upgrade.service to /etc/systemd/system/autoupdate.service and customized it.

WantedBy=shutdown.target

At least I enabeled the service:

systemctl enable --now autoupdate.service

Edit: Pacman needs to update its database. So I edited /etc/cron.daily/autoupdate.

It’s not what you said you did.

Drop in files are there to add your changes to the default file, that way you get the newest version but with your changes. The alternative is to copy the file to /etc/systemd/system and edit it, but that file will never be updated unless you do it.
