error: config file /etc/landscape/client.conf can't be read

running /usr/bin/landscape-sysinfo exit also with the error and the sysinfo get not displayed :(

touch /etc/landscape/client.conf
fixed the error and the sysinfo get displayed. But I think, we should ask in the script, if the file exist or not.

But sysinfo get not displayed over remote shell (ssh) - like it was before :(

ok, after a second logon the motd sysinfo get also displayed on ssh.

landscape-common 13.07.3 doesn't exhibit this, and it also doesn't install /etc/landscape/client.conf

This seems to fix it. Why it wasn't needed in 13.07.3 I don't know yet, could be related to the change from ConfigParser to ConfigObj.

     if sysinfo is None:

+ config.load(args, accept_nonexistent_config=True)
     for plugin in config.get_plugins():
         sysinfo.add(plugin)

I'll test this.

The problem with that fix is that it will silently ignore config files you give in the command line that don't exist:

# l /etc/landscape/client.conf
ls: cannot access /etc/landscape/client.conf: No such file or directory

# landscape-sysinfo -c /foo/bar/does/not/exist
(...)

To clarify, both 13.07.3 and 14.01 present the same behavior if accept_nonexistent_config=True. It's just that 13.07.3 didn't need it.

The fix needs to be slightly different. This is how 13.07.3 behaves:

In summary, sysinfo in 14.01 should not complain if:
a) the *default* config file does not exist
b) the *default* config file is not readable

It should complain if the file specified by -c:
a) does not exist
b) is not readable

This bug was fixed in the package landscape-client - 14.01-0ubuntu3

landscape-client (14.01-0ubuntu3) trusty; urgency=medium

  * landscape-sysinfo should ignore non existent or unreadable default
    config files. (LP: #1293990)
