Questions[blender](ubuntu)

I'm running Ubuntu 18.04 (Kubuntu, actually) on a Lenovo ThinkPad L540.

I installed the latest Blender from the PPA repository like so:

sudo add-apt-repository ppa:thomas-schiex/blender
sudo apt install blender

(The version string is 94552-4c0cca78eb4-0thomas~bionic0 and the description includes This is version 2.8 obtained by pulling the last version in the master branch of the blender git repository. According to the Blender website, that should be 2.82a.)

Attempting to run this new blender gives the error:

/usr/lib/blender/blender: error while loading shared libraries: libLLVM-6.0.so.1: cannot open shared object file: No such file or directory

I then discovered that my scrollback history wasn't set up right, so I don't have the list of packages installed when I ran the earlier commands.

I'd earlier (a year ago) installed Blender 2.80 manually (not from a .deb but from a tarball); that installation still opens without complaining about libraries.

I've searched the error and libLLVM online and found a suggestion to use sudo /sbin/ldconfig -v, which (after checking the man page) I tried, but it had no effect; the error on trying to run the new blender is exactly the same, including in a new Konsole window.

1. How can I get the dependencies installed correctly so the program will open, and
2. Is there somewhere I should report this as a bug?

I am trying 3 years now installing Autocad,*3ds Max* and Revit architecture on Ubuntu with wine!

Every year I am very optimistic 'cause I see the new wine versions already improved.

So, now I am starting again in a clean Ubuntu installation to install Autocad 2013 with wine 1.4. I am not trying to have an answer only for me, but I want this community to try and finally we can achieve that!

The winetricks have already net framework 4 to install which is the reason I have not already ran to the past Autocad.

So, I would like to remove completely my windows 7 partition from my pc and go on a linux machine without loosing the powerfull architectural programms.I know all about Blender and staff so I just want you to help find a solution on that, because I know there is a solution!

Maybe I will have to learn all the c++ or python etc. But I am sure that a solution can come with the help of all of us!

Any suggestion about this problem will be very nice and helpfull.

I installed Blender from official Ubuntu repository but its version is always behind the version available from the official Blender website.

I'm aware that I can launch the program within the downloaded folder, but i want to replace the install version with a new version downloaded from the website?

It must be present in the unity launcher.

I'm also aware of the available PPA's that are available, however I just want to install Blender manually.

Thanks in advance

For instance for mechanical engineering; from what I've seen, Blender is quite flexible and powerful so maybe it serves well for this also?

I am interested in trying out the Blender 2.54 beta, but don't have the time or patience to download and install all of the dependencies for it and compile it myself.

Is there a PPA somewhere that I can use to obtain a pre-compiled package for it?
