I've updated some of my hosts using this ppa. After the update I got the following error message:

gui_rpc_auth.cfg exist but can't be read. Check the file permissions.

The owner is changed to root, the group is boinc, and the access rights were

rw- r-- ---

I've changed the owner to boinc, and the access rights to

rw- rw- r--

After that on some of my updated hosts I've received another error message:

invalid client PRC password. Try reinstalling BOINC.

To my surprise the

/etc/boinc-client/gui_rpc_auth.cfg

file was empty on these hosts. I fixed this error by editing this file, putting a random 32-digit hex number in it.
After all of the above, the BOINC manager executable gets stuck on two of my hosts when I exit the GUI, and I can't relaunch it until I kill the stucked boincmgr.

Yes, the new client has a change that does not allow an empty gui_rpc_auth.cfg file anymore.

To get around the permissions problem of accessing gui_rpc_auth.cfg with the new client and return the client and manager to somewhat the same behavior as previous versions you need to add a new file with a pointer to the data directory.

.. so after some research, this happens due to these changes merged in March: https://github.com/BOINC/boinc/pull/3709

Fortunately, previous behaviour can easily be restored by adding a /etc/boinc-client/config.properties file containing:

> data_dir=/var/lib/boinc

That points boincmgr and boinccmd where to find the gui_rpc_auth.cfg file to read the password from.
In order for a random password (in case of an empty file) to be written successfully, I think I had to change the permission for either the sym link /var/lib/boinc-client/gui_rpc_auth.cfg or the actual file in /etc.
