After upgrade to 20.04 Files (and Krusader!) can find the volumes on local NAS, but individual files and folders are returned as "No such file or folder; has it been deleted?".
Taking note of previous related posts I have tried:
sudo gedit /etc/samba/smb.conf
workgroup = WORKGROUP client min protocol = NT1 server max protocol = NT1 client min protocol = CORE
Not sure what else to try. The 18.04 box still works perfectly and I can't work out if it is a Nautilus, Gnome, Samba, or (unlikely) a kernel thing. Stumped! Can anyone help?
