Cannot save file in shared folder

[Garpusha]

Hi. My apologies if this issue was discussed hundred times.

Got fresh installed Kubuntu on Ubuntu 22.04.3 LTS.
Have a host in local nework under Win7 with shared folders. These folders are visible in Dolphin and I able to copy files there via Dolphin.

Also I mounted them in fstab:

//192.168.0.99/D/Temp /home/flash/torrents/ cifs credentials=/root/.smbcredentials,noperm,iocharset=utf8,file_mode=07 77,dir_mode=0777 0 0
//192.168.0.99/D /home/flash/Media/ cifs credentials=/root/.smbcredentials,noperm,iocharset=utf8,file_mode=07 77,dir_mode=0777 0 0

While I'm saving any file from application to the mounted folder - it's ok, but when I'm trying to save to shared folder I'm receiving an error. Opera and Firefox say "Remote files not accepted - Portal / You can only select local files", LibreOffice says "Error saving document Object not accessible. The object cannot be accessed due to insufficient user rights".

Why this is happening? Where I can check these rights? I gave credentials to Samba and it's fine via Dolphin.

Thanks in advance!

just in case - smb.conf:
[global]

name resolve order = bcast host lmhosts wins
workgroup = MYGROUP
server string = %h server (Samba, Ubuntu)
log file = /var/log/samba/log.%m
max log size = 1000
logging = file
panic action = /usr/share/samba/panic-action %d
server role = standalone server
obey pam restrictions = yes
unix password sync = yes
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
pam password change = yes
map to guest = bad user

[printers]
comment = All Printers
browseable = no
path = /var/spool/samba
printable = yes
guest ok = no
read only = yes
create mask = 0700

[print$]

What exactly do you mean by "mounted folder" vs. "shared folder" ?

The Opera/Firefox issue might be addressed here.


As far as LibreOffice this solution was offered elsewhere on the web. I have not tried it as I do not have your issue:

In LibreOffice, go to Tools > Options... > Advanced > Open Expert Configuration.
In the search bar enter "uselocking".
Double-click on "true" to toggle it to "false".
Then click "OK" twice and try again.

Opera and Firefox say "Remote files not accepted - Portal / You can only select local files",

This will be a feature/setting from Snap or Flatpak.
For Snaps, read this for different methods and tools to allow network access, or outside of your home directories.,
For Flatpak, you can install Flatseal to change access permissions for that.

//192.168.0.99/D /home/flash/Media/ cifs credentials=/root/.smbcredentials,noperm,iocharset=utf8,file_mode=07 77,dir_mode=0777 0 0

Why is your credentials file in the root user account's home (/root/)?? This may be the whole issue here, since it can't be read unless you are logged in as root. Which is not normally available in *buntu to begin with.

I have shared folder on another LAN PC. I can access it via file manager like Dolphin smb://my_host/my_folder or mount it using mnt /my_local_folder /remote_folder bla-bla

The Opera/Firefox issue might be addressed here.

I'm afraid the issue is not with Opera or FF because even LibreOffice cannot work with it. It's kind of system issue i suppose. The way you offered with Libre configuration did not work unfortunately.

Actually did not get your point but will read it carefully later, thanks.

Well, I tried to put credentials to my home folder and change path in fstab - nothing changed.

Applications installed as Snaps or Flatpak very often need permissions set to allow access to directories not in the user's home dir -- Firefox most certainly is a Snap.

Is it readable? You may need to chmod it to 600 if you simply copied it over, especially if you are using a root account to do so.
You can aslo test the username/password by specifyiing them directly in the fstab instead of using a file, for testing purposes.

You may just have problems with share permissions, or the fstab entry, but samba always has been a pain for me.

Does it work any differently using the Network folder on Dolphin's sidebar, instead of manually mounting or using the fstab?

I have shared folder on another LAN PC. I can access it via file manager like Dolphin smb://my_host/my_folder or mount it using mnt /my_local_folder /remote_folder bla-bla

I would say that you need to look at the settings and permissions used for this share and match that to your Win 7 settings, particularly the SMB protocol version used there. if it is using SMB version 1 (highly insecure) it will not be supported out of the box.

OK, so this is confusing because any folder is a mounted folder. "shared folder" or "networked folder" vs. "local folder" would have been more clear. SMB mounts are mounted folders. The difference isn't mounted vs. not-mounted., it's local vs. shared.

Sorry for the pause, was tired of Linux)

Will check, ok

Yes it's readable and it's being mounted fine and it works - to save to mounted network folder.

Yes, I cannot save via sidebar links or using network folder.

Yes, it's definitely permissions issue, I just tried to save a picture from KolourPaint via Dolphin network shortcuts and it worked. Seems I have to investigate this.

Thanks for your time.

It sounds like Snap or Flatpak application permissions, except maybe for Libreoffice.
Browsers as snap/flatpak usually have restricted filesystem access by default.
See my first post.

You can tell from this:

Yes, it's correct, Opera is installed via Snap. I tried to plug some connections which could be related to network (you see "manual" mark), no changes:

One more interesting point. I have installed Smb4k to check my connections, so Smb4k can see my mounted network folders but see no other hosts at all. I wonder could it be the reason or not.
