gui_rpc_auth.cfg exists bunt cannot read (7.16.15)

[mx75]

Describe the bug
A gui_rpc_auth.cfg (and possibly other) access problem.

Steps To Reproduce

1. open new terminal window (under my user, NOT boinc)
   2a. type: boincmgr (boincmgr message: "gui_rpc_auth.cfg not found Try reinstalling BOINC")
   2b. if run boincmgr on one of remote host, the message is: "gui_rpc_auth.cfg exists but can't be read. Check the file permissions"
2. close boincmgr
3. cd /var/lib/boinc-client (the boinc user's home directory)
4. type boincmgr (at now: run correctly, show projects, tasks, ....)

Expected behavior
A clear and concise description of what you expected to happen.
I want to run boincmgr from anywhere. (from any directory).

System Information
(on all the desktop computers that belong to me):

• OS: Ubuntu 20.04.1 LTS
• BOINC Version: 7.16.15+dfsg.is.7.16.11+dfsg+202009010931~ubuntu20.04.1

grepping journalctl -u boinc-client.service revealed it.. Commit 7883508 removed support for empty passwords, breaking the common (and arguably legitimate) usage pattern of allowing unauthenticated access if the sysadmin in charge decides so. Before:

gui_rpc_auth.cfg is empty - no GUI RPC password protection

After:

gui_rpc_auth.cfg is empty - assigning new GUI RPC password
Can't open gui_rpc_auth.cfg - fix permissions

💭 I became curious how software components can be improved further also for this issue.
