Public bug reported:
Title: BOINC 8.2.9 package on Ubuntu 26.04 LTS fails GUI RPC
authentication; upstream BOINC package works
Package:
boinc-client 8.2.9
Distribution:
Ubuntu 26.04 LTS (resolute)
Hardware:
* AMD Ryzen 7 3700X
* NVIDIA GeForce RTX 3080
* NVIDIA driver 595.71
* CUDA 13.2
Problem Description:
After a clean installation of the Ubuntu-packaged boinc-client (8.2.9),
the BOINC daemon starts normally and appears functional, but GUI RPC
communication is broken.
Observed behavior:
* boinc-client service starts successfully.
* BOINC listens on localhost TCP port 31416.
* CUDA and OpenCL devices are detected correctly.
* BOINC Manager cannot connect to the client.
* boinccmd cannot authenticate to the local daemon.
* Authentication fails even when a valid GUI RPC password is explicitly
specified.
* Removing and recreating gui_rpc_auth.cfg does not resolve the issue.
* A complete package purge and reinstall does not resolve the issue.
Relevant symptoms:
boinccmd --get_state
returns:
Authorization failure: -102
When the GUI RPC password file is empty:
boinccmd --host localhost --passwd "" --get_state
returns:
Operation failed: read() failed
Running as the boinc user:
sudo -u boinc boinccmd --get_state
returns:
Can't get RPC password: gui_rpc_auth.cfg exists but can't be read.
Only operations not requiring authorization will be allowed.
Operation failed: read() failed
Service status shows normal startup and GUI RPC initialization:
Setting up GUI RPC socket
The daemon successfully detects the GPU:
CUDA: NVIDIA GeForce RTX 3080
OpenCL: NVIDIA GeForce RTX 3080
Data directory:
/var/lib/boinc-client
RPC port:
127.0.0.1:31416
Workaround:
The Ubuntu package was completely removed and replaced with the official
upstream BOINC Linux installer from boinc.berkeley.edu.
After installing the upstream BOINC package:
* BOINC Manager connected immediately.
* boinccmd worked correctly.
* Einstein@Home project attachment succeeded.
* Work units downloaded successfully.
* GPU computation worked normally.
This suggests a packaging or integration issue specific to the Ubuntu
26.04 boinc-client package rather than a hardware, driver, CUDA, OpenCL,
or BOINC configuration problem.
