hi , i have download svn with the help of following command... "sudo apt-get install subversion" then this comes..... Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: libapr1 libaprutil1 libneon27-gnutls libpq5 libsvn1 Suggested packages: subversion-tools db4.6-util patch The following NEW packages will be installed: libapr1 libaprutil1 libneon27-gnutls libpq5 libsvn1 subversion after installing svn when i gave the command svn checkout https://brlcad.svn.sourceforge.net/svnroot/brlcad/brlcad/trunk brlcad the output is... svn: OPTIONS of 'https://brlcad.svn.sourceforge.net/svnroot/brlcad/brlcad/trunk': could not connect to server (https://brlcad.svn.sourceforge.net) so what should i do now??Please help.
