1) Questions and Answers : Unix/Linux : theory simulation gets error at 14-minute mark (Message 49944) Posted 12 Apr 2024 by snowball101 Post: I would also like to note that there is no warning/notice that additional software needs to be installed to run LHC tasks It is mentioned at the homepage as well as a couple of times at the FAQ page: https://lhcathome.cern.ch/lhcathome/ "Please note that some of the applications on LHC@home requre Virtual Box to be installed." I am aware of that notice and (just like any other newbie that follows guidance) I installed Virtualbox when installing Boinc. It should be more specific. Something like "LHC@home requires Virtualbox and CVMFS to be installed for most tasks to run properly. This is how to install CVMFS: https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5594#44232" Otherwise the task would not run, a search on bing would provide useless, the Boinc event logs would only report a failure and the newbie would (if they even know how to use the forums) ask the same question I did.
2) Questions and Answers : Unix/Linux : theory simulation gets error at 14-minute mark (Message 49932) Posted 11 Apr 2024 by snowball101 Post: Hi, sorry for the late reply. I ran sudo apt upgrade and AMDGPU ran into installation problems. APT now shows Brokencount>0 and I can do nothing with apt now. Trying to install anything would just return: But that is not going to be installed That (might) include compiling with APT. The official website of Boinc also does not have up-to-date versions of Boinc for Linux. I never knew getting an up-to-date version of Boinc was that complicated. Taking from the Ubuntu 23 sources does not seem easier either. Guess I ran into the very problem that flatpak was designed to solve-yet flatpak somehow cannot be used? I am not familiar with the flatpak concept. I only know it is designed to be a bundle with all the dependencies. If I could get Atlas/theory to run in Virtualbox only, would that solve the problem? Is there some way I could get Flatpak to ignore the container/direct it to virtualbox? The process is not a sandbox so it should not be that hard. I could also try using an appimage of Boinc. Not sure if that would somehow work. I might try the Boinc forum and see if they have any way to deal with this issue. I would also like to note that there is no warning/notice that additional software needs to be installed to run LHC tasks (except sixtrack) I do not know why. The detection should happen before tasks get downloaded (maybe a dummy task that detects the dependencies). CVMFS only comes up after a log check and another forum post. Newbies like me would keep asking questions and keep downloading ~300MB of files only for the programs to throw up an error. Unnecessary trouble for both sides. Anyway, thanks for the cues and I will try to learn more about (GNU?) Linux in the meantime.
3) Questions and Answers : Unix/Linux : theory simulation gets error at 14-minute mark (Message 49912) Posted 9 Apr 2024 by snowball101 Post: Thanks for all your help! I just upgraded to 22 LTS from 20 LTS back in December last year. And my GPU drivers only provide support for LTS releases. Personally, I also prefer LTS builds since I moved to Ubuntu due to Windows Update annoyances. I think upgrading again would be overkill. I also disabled native tasks as it seems Virtualbox versions would be more stable in my case. I was wondering if there is another way to install a stable version of Boinc... I did find this thread https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4840#36880 teaching how to build from source, however it seems a bit outdated and I am not sure if anything has changed. I could also just steal the deb packages from the Ubuntu 23 apt sources, but I am not sure if this would introduce compatibility issues etc. I am a linux noob after all. Any suggestions? Thanks.
4) Questions and Answers : Unix/Linux : theory simulation gets error at 14-minute mark (Message 49909) Posted 8 Apr 2024 by snowball101 Post: Thanks for the help. I thought that Flatpak versions of Boinc were not sandboxed because the Mangaer app detected my old version of APT Boinc client before I purged it. I will try turning off the native tasks instead. Is there a way that I can get a non-sandboxed Boinc which is stable (not alpha testing etc)? Apt gives me an old 2020 version which says it is only for testing and unstable.

CVMFS not installed. First go thru the messages, how to install for LHC@Home projects. sixtrack is no problem, but no work ftm. You need a good networkconnection to ISP and some own knowledge to work with this projects.
7) Questions and Answers : Unix/Linux : Atlas receiving error at the 10 minute mark (Message 49803) Posted 21 Mar 2024 by snowball101 Post: I also advise Linux newdomers to not use nano. Instead, type sudo nautilus (or search the name of the file browser) then you should be dropped into the files app find /etc/cvmfs then copy the default file and edit using text editor. Same for downloading the deb packages. Just download the files from your browser. https://ecsft.cern.ch/dist/cvmfs/cvmfs-release/cvmfs-release-latest_all.deb https://github.com/apptainer/singularity/releases/download/v3.8.7/singularity-container_3.8.7_amd64.deb open the files app ( again, I am using nautilus ) find your downloads directory, and right click. There should be a "open in terminal" option in the menu. In the terminal, de-package the file sudo dpkg -i <packagename>.deb manually delete the packages after all is set up. This should be a bit more user-friendly

I should note that default.conf should not be edited and it needs to be copied to create default.list. Then edit the parameters. This is my output: ThinkPad-R480:~/Downloads$ sudo cvmfs_config setup ThinkPad-R480:~/Downloads$ sudo cvmfs_config probe Probing /cvmfs/atlas.cern.ch... OK Probing /cvmfs/atlas-condb.cern.ch...

9) Questions and Answers : Unix/Linux : Atlas receiving error at the 10 minute mark (Message 49790) Posted 20 Mar 2024 by snowball101 Post: Do I have to use nano? What difference does sudo nautilus then editing with text editor make? I prefer using GUI where possible, so I make less wrongly typed commands.
10) Questions and Answers : Unix/Linux : Atlas receiving error at the 10 minute mark (Message 49770) Posted 14 Mar 2024 by snowball101 Post: Hi, I am new to LHC and just upgraded my computer to Ubuntu 22 My Boinc version is 7.22 flatpak version. The atlas tasks I get always show an error at the 10 minute mark each time I try to run them. The tasks also are huge compared to other task files from other projects, using more than 300 MB and taking 6 hours to download. After the same error persisted after several attempts, and after switching from the APT version of Boinc (7.18) to flatpak (7.22) , increasing swap file size to 8 GB. I eventually gave up and decided to disable the Atlas tasks in project preferences. After hitting the update button multiple times and restarting Boinc and my computer, Boinc somehow still managed to download a few Atlas tasks and the same exact error followed. Can anyone with the skills please tell me what is going wrong here? Thanks for your time.
11) Questions and Answers : Unix/Linux : [Android 13] LHC@home does not get any tasks (Message 48199) Posted 7 Jun 2023 by snowball101 Post: Hi there, Somehow I do not get a lot of LHC tasks compared to other projects. While tasks for my PC have slowly trickled in, my Android 13 Phone, a Xiaomi 12S, has gotten no tasks despite it having very good specs (so it should not have a problem computing them). I have looked in all preferences and there are no restrictions for getting tasks. Can anyone give me some clues? Thanks.
