Conflict between NTP and NTPDATE

[JoLa]

Hi,

if you select time synchronisation over the internet, NTP must be installed (offered in the dialog) . This results in a waiting loop (1 minute) after log in.
I found a hint in the internet concerning NTP and NTPDATE. Therefore I deinstalled NTPDATE, AFAIK installed per default. After this the waiting loop is gone.
Think that the package manager should do this automatically.

BS: Xubuntu 12.04

Have you tried reinstalling ntpdate to check it's really its fault? I don't see how it could create delays when logging in. Also please attach /var/log/daemon.log and ~/.xsession-errors when the problem happens.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal:

apport-collect 1015041

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Please also paste the output of:

time -p ntpdate -q ntp.ubuntu.com

Thanks!

After several restarts I thought that there must be another behavior which causes the loop. I don't payed attention, that I had changed the login to using password. In this case the loop exists. Without password I had no loop with and without NTPDATE for several restarts.

But with the last restart I had a loop with login without password. I deinstalled NTPDATE and had no loop after restart.

Strange behaviour. I give up as these things are to heavy for me.

Adding syslog as attachement where you can see the time leaks.

Could you have a look to find out what was/is process 1681?

Please also attach ~/.xsession-errors.

Meanwhile I had installed Ubuntu: As the unity desktop is not my thing I installed Xubuntu again and found two reasons for the time leaks in the syslog, but not at the same starts of OS.

1. Setting of IPv6 in the networkmanager. I set it to 'ignore'.
2. NTP Server in 'ntp.conf'. I changed it to this:

server ptbtime1.ptb.de
server ptbtime2.ptb.de
server ptbtime3.ptb.de

# Use Ubuntu's ntp server as a fallback.
# server de.pool.ntp.org

Since deactivating the fallback server Xubuntu starts without loop about fifty times till now.

[JoLa (josef-latt)]

Not really the reason. After user log out and log in, which I do rarely, the loop comes back.

[JoLa (josef-latt)]

May be: Installing Xubuntu I used the home-partition of ubuntu. Before I deleted most of the files and directories meaning that they are relevant for the unity desktop.

Now I will do it again and leave only those applications, which have nothing to do with the system. E.g. Firefox and Thunderbird profiles.

You can close it.
