[SOLVED] systemd-swap issue

Hi,

My system has become unstable after I installed systemd-swap:

Any idea how I can fix it?

Re: [SOLVED] systemd-swap issue

Post the exact steps you took to install and configure systemd-swap. I don't run systemd-swap, but the Arch Wiki says there's a number of configuration steps you must take described on their GitHub readme. Did you follow all those steps?

I only followed the wiki step-by-step

Yes, I also went on this GitHub page and followed their procedure. Most of the time, it starts well though: https://x0.at/uj_

Re: [SOLVED] systemd-swap issue

If you disable dhcpcd@enp0s26f7u2.service can you reproduce the issue?

Well done, it's related: if the service dhcpcd@enp0s26f7u2 starts before the swap is allocated, the boot fails.

Where did you get that service name from or did you just make it up?

Re: [SOLVED] systemd-swap issue

@jones: it's the service that fails in the logs that OP linked:

systemd[1]: Starting dhcpcd on enp0s26f7u2...
dhcpcd[999]: sending commands to dhcpcd process
systemd[1]: dhcpcd@enp0s26f7u2.service: Can't open PID file /run/dhcpcd/enp0s26f7u2.pid (yet?) after start: Operation not permitted
systemd[1]: dhcpcd@enp0s26f7u2.service: Failed with result 'protocol'.
systemd[1]: Failed to start dhcpcd on enp0s26f7u2.

Re: [SOLVED] systemd-swap issue

There is / was an open bug report on https://bugs.archlinux.org/ for dhcpcd I can not provide a link as currently my system can not connect to the server.

It's my mobile USB tethering

Then, it seems it's solved. Many thanks for your help(s)
