[Bug 1895157] [NEW] Boinc cannot enable RPC access to start client or manager

[ikesterhaney]

Public bug reported:

Boinc Manager and Boinc Client cannot start in Xubuntu 20.10 due to an RPC issue.
Boinc Manager starts with a connection error - gui_rpc_auth.cfg exists but cannot be read. Check the file permission. - The file is a link and flagged as root/root in the var/lib/boinc and points to the /etc/boinc as root/boinc

a sudo boinc leads to the following messages on the terminal.
