Every boot I see failed to start manage swa*n zram. * stands for letter that is not displayed correctly, so I don’t know what it is. I use btrfs and swap file (instead of swap partition).
I think I don’t use zram, and least I don’t remember doing anything related to zram and I don’t know what it is.

sudo swapoff /dev/zram0
swapoff: /dev/zram0: swapoff failed: No such file or folder
sudo rmmod zram
rmmod: ERROR: Module zram is not currently loaded
zram is not installed or started
Have you created your swap file similar to what is described in this guide?

So, why the problem occurs? I use swapfile more than half a year and only after recent updates have started to experience problem.
Yes. And it works just fine.

This is error as displayed:

I did:
sudo systemctl disable systemd-swap
sudo systemctl stop systemd-swap
sudo systemctl mask systemd-swap
And the problem is solved.
But this just disables the sytemd-swap, right?
You may have encountered the same problem I did.
systemd-swap conf files have recently been changed : No swapfile ! · Issue #172 · Nefelim4ag/systemd-swap · GitHub
BTW, I found zram not being very efficient and I rather use zswap & swapfc (there also are rationales for that)
Uninstalling/reinstalling systemd-swap and properly amending conf files does the trick (french tuto with easy translation here )

It is supposed to do so. But when I do
swapon
NAME TYPE SIZE USED PRIO
/swap/swapfile file 1024M 13,8M -2
So, swap file is working.
@nam1962 Thank you for information. I will look into that.
