It's 2023 now, and I just ran across this problem. What is the solution?

I searched on Google and found people having variations of this or similar problems since 2018. That FIVE years.

The newest discussion I found on Google (and don't find anymore) explained that this is an issue with the Kernel and some cgroups. When upgrading the release to 22.10 and installing proposed kernels didn't help, I was about to uninstall Ubuntu that I just used to replace the outdated Macos on my kids computers. I told them Linux is faster, just as beautiful and there are no issues with random stuff not working.

By replacing APT packages with snaps you are forcing your users to use snaps. I have no quarrels with snap. Go ahead and replace Debian with it. But at least make them work for Gods sake.

If you don't care for human users and want to get big in cloud enterprise, that's fine too, just tell us that we're no longer relevant as users. I choose ubuntu exactly because I did not want to be bothered by having to fix my kids computers. I choose ubuntu for my work environment because it worked so far. I'm using Linux since it was first published. I have no sensibility that creating home directories in a place other than /home is a problem that will lead to basic programs such as browsers not working anymore.

When I see an error message "Permission denied", I expect to see a filesystem object with permissions denying access, not a directory to which that very user actually has full access.

This is the output of `mount`:

A lot of stuff to post, right?

Out of these, here are the things I saw mount show me at a time when mount was related to actual mounts of filesystems:

```
/dev/mapper/ubuntu--vg-ubuntu--lv on /var/snap/firefox/common/host-hunspell type ext4 (ro,noexec,noatime)
/dev/sdb2 on /boot type ext4 (rw,relatime)
/dev/sdb1 on /boot/efi type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
/dev/mapper/ubuntu--vg-lv--home on /home type ext4 (rw,relatime)
```

Except that `/dev/mapper/ubuntu--vg-ubuntu--lv` should actually be mounted as `/`. I have no idea what that entry can possibly mean.

Also, why are there **NFS** mounts? I don't want NFS on that computer. I don't need it. I did not tell Ubuntu to mount strange NFS file systems from somehwere. Why NFS of all choices????

I'm working with Unixes for more than 30 years and I have not the slightest clue what all of this chaos is about.

And what for? So that stuff like firefox can run safely in a sandbox? **SAFELY**? How many bugs and security holes are in these myriad layers of unnecessary complexity you create here? I don't know. You don't know either, because otherwise I would not experience a bug that you could not fix in more than 4 years.


This is a monumental catastrophe in terms of user experience.
