Title:
switch to wget results in no motd-news in clouds
Status in base-files package in Ubuntu:
Fix Released
Bug description:
cloud-specific motd news relies on the user-agent string cloud_id
/<cloud-name> being included in the user-agent. The server, when
receiving this string, will try to return the cloud-specific index
file, which is `index.txt.<cloud-name>`. If that file doesn't exist,
then the 404 error document is returned, which happens to be set to
the default `index.txt` normal motd-news file.
curl happily returns that without flagging this as an error situation
(a 404: it needs an extra command-line argument for that). wget,
however, fails without printing the error document:
$ wget -U cloud_id/aws https://motd.ubuntu.com -O-

We need to pass --content-on-error, ignore the error status 8 (or all?) and
make it quiet (-q):
$ wget -U cloud_id/aws https://motd.ubuntu.com -O- --content-on-error -q ;
