lsmod looks suspiciously equal and wrong

After having an issue with snap which is not able to mount into /tmp/... I came to this issue where loop module should be loaded.

$ sudo modprobe loop
modprobe: FATAL: Module loop not found in directory /lib/modules/5.4.0

and lsmod finally shows

and also this here should not be there.

I have a kind of a feeling that something is wrong here. And I also sense that there are multiple issues.

EDIT: The installation is a providers image:

 $ uname -a
Linux x.y.z 5.4.0 #1 SMP Fri Nov 20 21:47:55 MSK 2020 x86_64 x86_64 x86_64 GNU/Linux
$ apt-cache policy linux-image-generic
linux-image-generic:
  Installed: (none)
  Candidate: 5.4.0.89.93
  Version table:
     5.4.0.89.93 500
        500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages
     5.4.0.26.32 500
        500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages

so maybe I should invest my time in installing Ubuntu from scratch?

Are you on a VPS or something? Add the output of `uname -a` and `apt-cache policy linux-image-generic` please (or whichever kernel package you're using, if not `generic`)

Indeed it's a VPS. Is there general problem with that and ```snap``` ?

Well, depending on the virtualization method used, your instance might not have its own kernel - it might be using the host system's, so you wouldn't be able to do anything that affects kernel settings. That in turn might cause problems with enabling container-based systems like snaps.

The hoster support just responded. But it would be possible in my special case to install from a different image where kernel settings would be available!

RO: lsmod pare suspect de egal și greșit

RU: lsmod выглядит подозрительно равным и неправильным

VI: lsmod trông giống nhau và sai một cách đáng ngờ

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.
