Comment 57 for bug 1872476

I apologize for the delay, but I'm now starting to investigate this problem.

As Christian said above, the very first step I have to take is to reproduce the problem, but for now I am unable to do so. Here is what I did:

1) Installed a Focal VM from scratch. Made sure that everything is up-to-date.

2) Installed samba smbclient gvfs gvfs-backends dbus-x11.

3) Edited /etc/samba/smb.conf and added the following lines:

[testshare]
   comment = Samba Shared Folder
   path = /testshare
   writable = yes
   browsable = yes
   create mask = 0660
   directory mask = 0771
   valid users = sergio

[testshare2]
        writeable = yes
        path = /testshare2
        guest ok = yes
        browseable = yes
        follow symlinks = yes
        wide links = yes
        directory mask = 0755
        directory mask = 0644
        force user = sergio

4) Added my user to Samba using smbpasswd.

5) Created /testshare and /testshare2, then created new text files inside them.

6) Opened Nautilus (using my regular user, not root) and mounted the "testshare" and "testshare2" shares.

7) Also verified that I'm using SMB3_11 via smbstatus. I have also tried forcing the usage of SMB3_02 (which is what Lee Tae Hoon said he was using).

I verified that the text file is correctly being showed as a regular file, not a directory. I also tried downloading some JPEG images from the internet and putting them inside the shares, but they always show up correctly as regular files.

I understand that this bug is affecting multiple users, but I'm trying to find a way to reproduce it locally so that I can investigate it more.

I have a few questions:

1) Aside from the share definition you shared above, is there anything else that you may have changed in /etc/samba/smb.conf? Would it be possible to share the whole file, taking care to obfuscate any personal information?

2) Can you share/examine the contents of /var/log/samba/log.<YOUR_HOSTNAME>?

3) Can you set Samba's log level to the maximum value and reload the share? You can set the log level by doing (as root):

# smbcontrol smbd debug 10

Then, after you refresh Nautilus, you should set the debug level back to 0:

# smbcontrol smbd debug 0

If you could share your log files under /var/log/samba/log.*, that would be great.

Thank you.
