Nemo: A problem with the preview cache has been detected

Hello everyone.
I have a cinnamon 20.2 on a sandisk SSD 500GB. I have installed “” on a btfrs partition, and “home” in a ntfs partition. The system runs fine, but whenever i call nemo, a message appears in it’s window:
“E’ stato rilevato un problema con la cache delle anteprime. Sistemarlo richiede privilegi amministrativi” with two buttons ( to correct the problem ).
I try to correct, but the problem persists.
If i run nemo in a terminal, i obtain the following error message:
Nemo-Share-Message: 19:31:31.569: Called “net usershare info” but it failed: «net usershare» ha restituito l’errore 1: Can’t load /etc/samba/smb.conf - run testparm to debug it
Any idea ?

/home must reside on a partition with a filesystem that supports POSIX file ownership and permissions.

ntfs does not support those, and the ownership and permissions you see in a filemanager for anything residing on ntfs or a FAT-based filesystem are virtual. They are applied to everything on the filesystem at mount time, and they only exist in the virtual filesystem layer. They cannot be stored on the filesystem, and they cannot be altered for individual files.

In addition to the above, ntfs also does not support POSIX hard links, symbolic links or pipes.

I’m afraid you’re going to have to reinstall… :man_shrugging:


I have Manjaro Cinnamon installed on a Sandisk SSD and it runs perfectly. It’s the best running Linux distro I’ve ever used. Follow Aragorn’s suggestion. You’ll like the results.

People: use ext4.
Microsoft: but it’s open-source.

People: use ntfs.
Linux: but it’s crap.

@Frank62 : I want my crap back!

Hi @Aragorn
Ok; can I at least mount a harmless folder like / home / user / download to an ntfs partition?

Why the hell do you want an ntfs so bad?

Yes, you can do that, if you set it up with the proper mount options in /etc/fstab.


You could always replace the folder ~/Downloads/ with a symbolic link to an NTFS folder

That is possible too, but then the mountpoint would not necessarily be static ─ it could still depend on the auto-mounting by systemd ─ and there could be additional permissions issues. It would make much more sense to mount the ntfs filesystem directly to ~/Downloads via an entry in /etc/fstab, looking something like this… :arrow_down:

UUID=the-UUID-of-the-NTFS-partition  /home/frank62/Downloads  ntfs-3g  auto,nofail,uid=1000,gid=1000,utf8,umask=022,defaults   0   0
