Hi,

I am stumped. I have had success installing and running Boinc on several older computers. I've even had it installed on this one too in the recent past. Then, I upgraded this computer to Astronomy Linux running Ubuntu 21.10 OS. Now, no joy. I am cross posting this to both to Einsten@home and the Boinc websites.

This is an HP computer.

I have installed and re-installed Boinc and after apparently fixing one issue now I get the following error message:

Invalid client RPC password Try reinstalling Boinc.

HP Pavilion Notebook
5.9 GiB RAM
AMD A6-6310 APU
Radeon r4 graphics (AMD Kabini)
Ubuntu 21.10
64 bit
Wayland


So far I haven't located a resolution that works for this. Any pointers or help on how to resolve this issue will be most greatly appreciated.

Regards,

John

Add yourself to the user group boinc and give yourself rw permissions to /var/lib/boinc-client.

I hope I have that right from memory. It has been discussed here in the past.

I know enough about Linux to get into trouble but not always enough get out. Any system I put together 18.04 or 20.2, I always my account "jstateson" to get boinc and the GPU drivers.
When I edit cc_config or want to make changes to app_config I have to use sudo.

Looking at ownership and other properties I don't see any consistency and assume that is just the way Linux works. For the executable binary

jstateson@jysdualxeon1:/usr/bin$ ls -l boinc
-rwxr-xr-x 1 root root 20579552 Oct 22 20:43 boinc

but different here

jstateson@jysdualxeon1:/etc/boinc-client$ ls -l
total 24
-rw-rw-r-- 1 boinc boinc 2792 Oct 22 20:45 cc_config.xml

-rw-r----- 1 root  boinc   11 Oct 11 19:25 gui_rpc_auth.cfg
-rw-r--r-- 1 root  boinc  306 Apr 10  2020 remote_hosts.cfg
jstateson@jysdualxeon1:/etc/boinc-client$ cat config.properties
data_dir=/var/lib/boinc-client

and even the links from the data directory have different ownership than the targets which is confusing

jstateson@jysdualxeon1:/var/lib/boinc-client$ ls -l

The following two items are obviously different from the rest and also the target ownerships are just the opposite.

lrwxrwxrwx  1 boinc boinc     34 Apr 10  2020 ca-bundle.crt -> /etc/ssl/certs/ca-certificates.crt
lrwxrwxrwx  1 root  root      31 Oct 11 17:40 cc_config.xml -> /etc/boinc-client/cc_config.xml
-rw-rw-r-- 1 boinc boinc 2792 Oct 22 20:45 cc_config.xml
-rw-r--r-- 1 root root 199113 Sep 25 06:41 ca-certificates.crt

This system seems to be working fine Some Linux system the apt-get chooses an old version and on other occasions a suggestion is made (here at Berkeley) to use a repository run by someone who keeps the latest and greatest. I assume they (the repository gurus) know what they are doing.

Anyway, I assume all the above is correct since it works but it seems a mix of too many hands in the pot.

[edit] AFAICT I am not a "member of boinc" and do not even know how to join a boinc group but this system seems to work.

I think it's the group membership which is critical. Loads of 'HowTo' on the web, like https://linuxize.com/post/how-to-add-user-to-group-in-linux/

The command is

sudo usermod -a -G groupname username

where:
groupname is boinc
username is your Linux account name.

Do the usermod in terminal, and reboot the machine afterwards. Makes it easier to use the BOINC Manager.
