Hello,
I have an issues with access file shares from nfs,
normally samba works fine for me and I don't know where is the problem.
For example - when I want to access samba shares - simply type : smb://server in address bar and works fine,
When I want to access nfs shares I'm getting errors :

Could not mount device.
The reported error was:
Failed to mount /disk1/firma, /disk1/dominik-filmy, /disk1/temp

normally nfs share are as follow:

dominik@HP-Dominik:~$ showmount -e core
Export list for core:
/disk1/firma 10.10.0.0/27
/disk1/dominik-filmy 10.10.0.0/27
/disk1/temp 10.10.0.0/27
