after dist-upgrade to 20.04, file sharing stopped working
now when i try to connect to another Ubuntu computer, it shows "Unable to mount location - Failed to retrieve share list from server: invalid argument"
how can we troubleshoot and fix this as simple and easily as possible? and how to prevent this happening again in the next dist-upgrade? i think i have both samba and smbclient installed
(i think i only used samba up to now, i have no idea how to configure nfs, afp or others as alternative network protocols since i never used them at home)
