Cannot saved document located on public samba resources with help LibreOffice 6.1.3 (prev. version open/saved correct)


Could you please help me.

LibreOffice does not open files on the samba share.
While opening file with machine, which is a client and is working under Lubuntu 18.04, I become error:
Common input / output error when accessing /run/user/1000/gvfs/smb-share:server= , share = .
Important is, that the same version of LibreOffice opens files on samba share perfectly, if client machine is working under Lubuntu 16.04.
By opening file through menu of LibreOffice: File→Open I see samba share and can open files only for reading.
Installing of most earlier versions of LibreOffice does not take effect.

On Lubuntu 16.04 by default works samba 4.3.2. Lubuntu 18.04 installs by default libsmbclient and samba libraries of version 4.7.6. Downgrade to earlier versions of samba is impossible.

Ps. Downgrade to earlier version of Lubuntu is impossible too, because hardware of PC is to new and Lubuntu 16.04 is working incorrectly.

Not clear why did you close it as not relevant, but it’s possibly tdf#115747.

I cannot remake this situation. i do No know, but in 2 days, documents were correctly opened and saved on the samba share.

samba Version 4.3.11-Ubuntu

Client Ubuntu Ubuntu 14.04.5 LTS \n \l 4.4.0-138-generic

// /media/user/Share2 cifs username=,password=,rw,uid=1000,gid=1000,_netdev 0 0

Error saving the document : Error creating object.

I have found and applied one temproary solution:

in /etc/samba/smb.conf /section GLOBAL/ I have added one string:
client max protocol = NT1.

After doing this I am able to open files on the samba share through the menu of LibreOffice:
File → Open. But problem is still there. It is still impossible to open files directly from samba share through pcmanfm.
