Installed full version of Linux Ubuntu v18.04.2 LTS so I can run some of the Linux only Applications.Having a problem running the LHC Theory Native Wu's so far. They error out in just a few seconds running time. Are they a VBox Wu, they show MT so I'm assuming their a CPU Wu ???

Checked and as far as I know VirtualBox is installed. Don't know about the Lib files though if that is causing the error. I can't find the proper commands to install the lib files if that's what missing for the Wu's to run properly. If anybody knows the proper commands or a link that shows them for installing the Lib Files could you post them ... Thanks

This is not enough. Please follow instruction here to install extra software required to run them: https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4971.

Not having a VBox setup puts the burden on the user to have all the requirements.

Theory credits are stupidly low. Atlas is ok though and requires singularity setup but don't follow their guide as it will have you compiling everything instead of installing from repos.

To add onto the link Daniel posted here is my setup for CVFMS and Singularity

Atlas is still same app while Theory has separate apps selectable on LHC site and for WUProp.

I'd also recommend an app_config as they don't use all the CPU threads requested.

<app_config>

<app_version>
<app_name>Theory</app_name>
<plan_class>vbox64_mt_mcore</plan_class>
<avg_ncpus>1</avg_ncpus>
<cmdline>--nthreads 1</cmdline>
</app_version>

<app_version>
<app_name>TheoryN</app_name>
<plan_class>native_theory</plan_class>
<avg_ncpus>1</avg_ncpus>
<cmdline>--nthreads 1</cmdline>
</app_version>

<app_version>
<app_name>ATLAS</app_name>
<plan_class>vbox64_mt_mcore_atlas</plan_class>
<avg_ncpus>2</avg_ncpus>
<cmdline>--nthreads 2 --memory_size_mb 4800</cmdline>
</app_version>

<app_version>
<app_name>ATLAS</app_name>
<plan_class>native_mt</plan_class>
<avg_ncpus>4</avg_ncpus>
<cmdline>--nthreads 4</cmdline>
</app_version>
</app_config>

Not working for whatever reason ...

Crap now BOINC won't even connect, have network connected & can use Firefox but BOINC just spins it wheels without connecting ... Options to connect look okay ...

Weird: If I reboot BOINC will connect again but as soon as I shut BOINC off it won't reconnect again unless I reboot again ...

dpkg: error: dpkg frontend is locked by another process

Is there another install going? I'm guessing if so it would be cleared if you've reboot the PC since then.

I've used the instructions on several 18.04 systems.

Yeah already thought of that but been debating whether to just uninstall BOINC reinstall it again. There's no reason to have to reboot each time I exit BOINC in order to get it to start again. Check the process manager but nothing shows up there that another instance it running so something must be messed up.

May have to just wipe the Linux install out reinstall that, not a big deal since it's on the hard drive by itself ...

dpkg: error: dpkg frontend is locked by another process

Obviously, there is another process locking dpkg database. And reinstalling the whole system will not help you. Did you install desktop Ubuntu? There is usually process like "apt-daemon" or whatever (i dont remember exactly) which locks dpkg database and don't allow you to use apt-get or even dpkg. This daemon is supposed to be helper for desktop "Software Center" or whatever it is called now or some kind of autoupdater. Just one of the desktop Ubuntu stupidities. Find it, kill it and try again, and do not ignore errors.

PS: Last time I used Ubuntu as a desktop, the first thing I did after installation is to uninstall all that "user-friendly" bloatware daemons, auto-updaters and so on, lol. Good old aptitude (pseudo-graphical version of apt-get) ftw.

PPS: I installed everyting for Theory Native on my home Ubuntu Server 18.04 some days ago and everything is working fine.

dpkg: error: dpkg frontend is locked by another process

If you see the error “dpkg frontend is locked by another process” you’ll have to do the following:
First, find out the id of the process that is holding the lock file.

lsof /var/lib/dpkg/lock-frontend

The above command will give you the PID of the processes using the lock files. Use this PID to kill the process.

sudo kill -9 PID

Now you can remove the lock and reconfigure dpkg:

sudo rm /var/lib/dpkg/lock-frontend
sudo dpkg --configure -a

---

lsof /var/lib/dpkg/lock-frontend... doesn't show or do anything when entered in the terminal

Looks like you didn't start autofs service. Did you do cvmfs_config setup?

I have no idea what I started or didn't start. I really don't know anything about Linux or the commands needed to run certain things. I'm not worried if I run Theory Native or not, way to many commands & hoop jumping for me to worry about it, I thought there might be a simple solution but apparently not ...

Well whatever I did it possibly seems to have worked. For the heck of it I tried to get some work & the project gave me 2 WU's & they are running now past the 30 second mark anyway. Their up to 10% done so I assume their going to stay running ... Thanks for the help even if I didn't know what I was doing something worked

I have no idea what I started or didn't start. I really don't know anything about Linux or the commands needed to run certain things.

I asked a simple question: did you run "cvmfs_config setup" as described in the guide here https://cvmfs.readthedocs.io/en/stable/cpt-quickstart.html? Some people (including me) miss this step at first time.
The guide also says "reload the autofs service in order to apply an updated configuration" without specifying how to do this, it should be "systemctl restart autofs". And finally you can check status with "systemctl status autofs"

Simple answer is I DON'T KNOW but whatever I did it worked as I'm running the Wu's so it doesn't matter if i know or not does it ...
