[Bug 1952496] Re: ubuntu 20.04 LTS network problem

[Steven Abner]

Was forced to update to 20.04 which found solution to resolving/loading 
bug:

alter file /etc/systemd/resolved.conf to:
LLMNR=yes
MulticastDNS=yes

create file /etc/systemd/network/wifi.network with contents:
[Match]
Name=wlp3*

[Network]
DHCP=yes
LLMR=yes
MulticastDNS=yes

followed by:
sudo systemctl enable systemd-networkd
sudo systemctl start systemd-networkd

to fix smb loading in 'Network/Entire Network' of condition
for listed 'smb://Stevens-Mac-Mini.local:445/'
    Unable to Mount Folder
    Could not connect to the server for this folder.
    Failed to retrieve share list from server: Software caused 
connection abort
alter /etc/samba/smb.conf just under:
[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will 
part of
   workgroup = WORKGROUP
add:

   client max protocol = SMB3

Title:
  ubuntu 20.04 LTS network problem

Status in avahi package in Ubuntu:
  Expired

Bug description:
  Network afp only partially works. Two tries, Elementary OS 6, Ubuntu
  20.04 installs both have identical problem. Resolved by reinstalling
  Ubuntu 18.04 LTS. Using different kernels doesn't matter. Specific
  problem is with afp protocol name resolution. Searching local network
  for ip address using afp://ip_address did connect, but using GUI
  Files/Other Locations/Networks with named hosts will not. Always
  returns can't resolve hostname.local. Tried multiple edits of
  different network files, even installed netatalk in attempts. Again,
  solution is to go back to downgrade, works right out of the box, as
  did on another, and this before upgrade. This was only attempted with
  2 other computers, one mac, one ubuntu/elementary.
