Linux waking up after suspend immediately

in flag

After none of the solutions on the internet worked, I'm now asking here for help;

My system will not suspend or hibernate - it wakes up immediately.

I've disabled everything in /proc/acpi/wakeup using the command

for i in $(cat /proc/acpi/wakeup | grep enabled | awk '{print $1}'); 
  do 
    echo $i > /proc/acpi/wakeup; 
  done

which, predictably did nothing.

I'm not sure exactly how I found this out, but I saw something to do with network-manager preventing sleep, however I have no idea what to do with this information. Hence I hope to receive help here.

What is preventing my system from suspending?

Edit

To answer two important questions:

  1. No, Wake on *, including Wake on LAN etc are not enabled. I've confirmed this by checking in the BIOS. The option exists and is unchecked.

  2. My system is a Dell Inspiron 15 7570 running KUbuntu 22.04 system, running Kernel v 5.15.0-60-generic.

  3. The output of inxi -G is:

Maybe WoL is enabled in BIOS.

Is it 21.04, or 22.04?

Thanks for pointing it out. It's actually 22.04.

What does `inxi -G` say? Might be a GPU driver problem. Add the output to your question, not in the comments

Thanks, I've updated to provide the information

Have you explored errors in various system/kernel logs? Reviewing `dmesg`/`journalctl` output may be useful here.

I have. I've opened my system journal and found a wake request from `Network-Manager`, which unfortunately lead to a dead-end. I've looked for similar issues, but the programs which seem to be causing the issue, also don't seem to be installed. Frankly, this issue is so unlike anything I've come across, I'm asking here to help track it down.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
