Public bug reported:
I have a connection profile which is supposed to allow my computers to
talk to eachother over an ad-hoc eithernet connection. For me, this is
mostly useful for when I need to transfer large files over from one
computer to another (the only network I have is WiFi, and it's painfully
slow). So, If I need to transfer files from machine A to machine B, I
just use an eithernet cable. Easy-peasy.
However, after upgrading one of my machines from Ubuntu 16.04 to 18.04,
I find that said machine can no longer create such a network. If I try
to active the profile graphically using nm-applet, it fails without
displaying any error messages. However, If I try to activate it from the
command line with "nmcli con up id Wired\ Connection\ 2", it fails with
the following message:
Error: Connection activation failed: IP configuration could not be
reserved (no available address, timeout, etc.)
While typing this bug report, I ran the "ubuntu-bug network-manager"
command, and will post the results below. If there's anything else I can
do (I can't read/write code very well, but I can test code, and get any
additional information, so long as I'm given clear instructions on how
to do so), please let me know.
