This error occurs because indigo has a new SSH host key. Please edit your “known_hosts” file on your local system, and remove entries relating to indigo (indigo,indigo.eecs.yorku.ca,eecs.yorku.ca). Now you will be able to login without the warning.

At jobs and cron jobs are not transferred between systems. You will need to recreate your at and cron jobs on the new system.

Remove the file ~/.vnc/xstartup in your home directory, then restart vncserver on indigo. A new .vnc/xstartup file will be created, and you will now be able to connect with vncviewer. The old file which was created with the older vncserver is no longer compatible with the system setup.

The local version of the svn command (/eecs/local/bin/svn) was compiled with CentOS 6, and this linked to an older version of a dynamic library (libsasl2.so.2) which has been updated on CentOS 7. This is fixed temporarily on indigo. However, /usr/bin/svn client (the one provided by the OS) will also work in the meantime.

Recommended- Can you trying setting the LD_LIBRARY_PATH and running your grading scripts. setenv LD_LIBRARY_PATH /eecs/local/lib64

The GNU Fortran compiler f77 has been renamed to gfortran under CentOS 7. f77 version was 3.4.6. gfortran version is 4.8.5.

This occurred because the .xsession was not set to the current default Contained “exec /cs/local/share/system.xfce”. Updated to the default(~template/.xsession) Many users still have this old profile You can copy the ~template/.xsession to replace your existing one

You may be using an old ~/.Xresources file . Remove ~/.Xresources

On CentOS 7 , you will get the following error if you run gedit remotely: (ssh to another host): WARNING: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-xxxxxx: Connection refused If you are using gedit on your desktop , it will work properly. You can choose to use another editor like emacs or geany. You can workaround the “Failed to connect to socket..” by setting the environment variable “NO_AT_BRIDGE to 1” eg : setenv NO_AT_BRIDGE 1 and then run “gedit”

This failed because the script is python based and needs a module “gi” If a user has his/her environment variable LD_LIBRARY_PATH set to /cs/local/lib, it will fail. The work around is to unset the environment variable and run gnome-tweak-tool . An alternative is to add the “gi” module to our installed python in /cs/local/bin
