WARNING: clock of the subversion server appears to be out of sync. This can result in inconsistent check out behavior.
This message seems pretty clear, to fix this we have to configure ntp. Let’s install the required packages :
apt-get install ntp ntpdate
vim /etc/ntp.conf
add server ntp.belnet.be
# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server will # pick a different set every time it starts up. Please consider joining the # pool: <http://www.pool.ntp.org/join.html> #server 0.debian.pool.ntp.org iburst dynamic #server 1.debian.pool.ntp.org iburst dynamic #server 2.debian.pool.ntp.org iburst dynamic #server 3.debian.pool.ntp.org iburst dynamic server ntp.belnet.be ...
Restart ntp,
/etc/init.d/ntp restart
You can check your configuration and see the servers with which you are synchronized with the following :
ntpq -p
