I am getting the above error and have not been able to fix it.

Reinstalling BOINC did not work.

I googled some possible remedies but had no success. In particular I followed the procedure here: https://techoverflow.net/2021/11/29/how-i-fixed-ubuntu-boinc-invalid-client-rpc-password-try-reinstalling-boinc/

# Generate new RPC password
sudo apt -y install pwgen
pwgen 30 1 | sudo tee /etc/boinc-client/gui_rpc_auth.cfg
# Fix some permissions
sudo chown root:boinc /etc/boinc-client/gui_rpc_auth.cfg
sudo chown root:boinc /var/lib/boinc/gui_rpc_auth.cfg
# Add current user to BOINC group
sudo usermod -a -G boinc $USER
# Restart BOINC client
sudo systemctl restart boinc-client

I am in group boinc:

$ groups
rsholmes adm tty dialout cdrom sudo audio dip plugdev users lpadmin sambashare boinc libvirt

File permissions:

$ ls -l /etc/boinc-client/gui_rpc_auth.cfg
-rw-r----- 1 root boinc 1 Jan 26  2022 /etc/boinc-client/gui_rpc_auth.cfg
$ ls -l /var/lib/boinc/gui_rpc_auth.cfg
lrwxrwxrwx 1 root root 34 Feb 12 22:14 /var/lib/boinc/gui_rpc_auth.cfg -> /etc/boinc-client/gui_rpc_auth.cfg
$ ls -ld /var/lib/boinc-client/
drwxrwxr-x 5 boinc boinc 4096 Feb 12 22:39 /var/lib/boinc-client/

boincmgr version is 7.18.1
OS is Linux Mint 21.2

Reinstallation was done according to https://boinc.berkeley.edu/wiki/Installing_BOINC_on_Debian_or_Ubuntu .

As well as adding myself to the boinc group I always give myself read and write permissions to /var/lib'boinc-client. There are several threads on these forums about this issue but I don't have a machine free to test which one works on a default installation at the moment having stopped using the repositories and building the client and manager from source.

** /var/lib/boinc-client **

Using a /home located folder for BOINC solves a multitude of problems. I personally like the original Berkeley installer version colloquially known as the All-In-One installation.

I notice that clicking on the link, Firefox objects because the file is downloaded via http rather than https. Not an insurmountable issue and I would be prepared to accept the security risk.

See above,

I had boinc and boincmgr installed, it was working fine. Then it started giving me these errors.

I am not enthusiastic about running software downloaded from a random site I never heard of especially with no documentation or description.

Is there no way to get this site's software working? It *was* working and then suddenly it wasn't.

Lunatics was the original expert or power user Seti app, tech tips, utilities website. Been around forever. Forums are no longer there but all the special apps are still available.

The two devs that developed the SETI applications hung out there.

The BOINC.zip file is what is referred to as the All-in-One version of Boinc. It is a full installation of Boinc that is just unzipped into your /home directory. Everything is already set up with all files and folders in place with the local user permissions set.

To get Boinc running all one needs to do is unpack the file and double-click on the Boinc Manager and that starts the Boinc client. Just need to start adding projects via the standard Manager interface.

Older client that was compiled under Ubuntu 20.04 so you need to add the older OpenSSL 1.1 library to get it to run under Ubuntu 22.04 or later because the those later versions dropped 1.1 versions and moved to 3.0 versions of OpenSSL.

Just wanted to point out the easy way to solve your issue. There is a much harder way to move all the files, folders, links and permissions of a distro version of BOINC into the /home folder if you want to go that way. As long as you are comfortable with the command line and have some time, you can get the newer repo versions moved to /home also.

In other words, no, this site's software is hopelessly broken?

Then I'll give up, I guess.

Up to you.

Works if you are still running any LTS of Ubuntu versions 20 or less.

I would have thought if everyone had this problem with versions 21.x and above of Ubuntu, we would have heard a lot more about it here.

I’m running Ubuntu 22.04 with Gianfranco’s version 7.20.5 and have had zero problems - certainly not “hopelessly broken”.

Only from users of the AIO. And from the previous post, I guess most people have never tried it. So no reports of any issues if there are not many using it.

All my teammates use it as the base BOINC configuration before adding more support for our special apps.
I never use any repo version BOINC unless the AIO is not available for the platform like with my Raspberry Pi's. Only then do I have to do the permissions dance with files and folders under root.

As, I stated, Ubuntu flavors past 20 have deprecated libssl1.1 library and only supply libssl3.0 now. But it is a simple fix to add the missing library back in with a download of the libssl1.1 library from the OpenSSL repository.

http://security.ubuntu.com/ubuntu/pool/main/o/openssl/openssl_1.1.1f-1ubuntu2.21_amd64.deb

sudo dpkg -i openssl_1.1.1f-1ubuntu2.21_amd64.deb

Then don't use it and continue to try and wrangle the distro repository versions of Boinc into submission. My previous posts tell the documentation and description of the AIO.
I think the AIO is a valid, no hassle choice. Just giving you more options that is all.
