Finally got #samba working again, again, on my #LXLE #Focal64 #linux box.
So annoying that it seems to regularly break after samba is updated.
This time I just could not get it to work again no matter how much I tinkered with smb.conf. In the end I just purged samba and reinstalled it.
After I added my smb user, added a share and restarted smbd, it all just worked . Now able to browse and read/write linux->windows and vice -versa! Hurrah!
And that smb.conf file has also been backed up...
