[Solved] Cant run FreeCAD after reinstalling

[abasel]

I was running FreeCAD on Fedora 29. I reimaged my machine installing Fedora 30.

I have now downloaded the latest AppImmage: FreeCAD_0.18-16131-Linux-Conda_Py3Qt5_glibc2.12-x86_64.AppImage

I copied it to /opt/freecad

When I run the following

sudo FreeCAD_0.18-16131-Linux-Conda_Py3Qt5_glibc2.12-x86_64.AppImage

I get

/tmp/.mount_FreeCAImobH5
FreeCAD 0.18, Libs: 0.18R16131 (Git)

[abasel@localhost freecad]$

The reason I run it under sudo the first time is to that the desktop file can be created.

What am I doing wrong?

I found the "dnf install freecad" option, so all good.

I would however like to know why the AppImage option failed.

I don't know why the AppImage failed, but in general it's a terrible idea to run regular user applications with "sudo". This gives elevated privileges to the application, which may write some files with "root" ownership; then if you try to run the same application as a regular user, you may not have the permission to access some of the files that the program wrote with elevated privileges.

If you are going to put stuff in /opt/ change the ownership of the containing folder to your regular user, so that you have complete control of the files inside, and you don't need sudo.

Code: Select all

sudo chown abasel:abasel /opt/freecad

You should never be required to run common applications like Firefox, Inkscape, Blender, FreeCAD, etc., with root, unless you have a very specific reason to do that.

Yes I agree but sometimes just do it on the first runs when the programme might create the desktop file; but point taken

... on the first runs when the programme might create the desktop file...

But why? The .desktop file should be provided by your package. Or it should be installed in the .local directory (or somewhere) in your user's home directory. No "sudo" needed either.

Aah there's my problem, I usually like storing it in a folder outside of my home directory...... self taught and not following best practice... one lives and learns.

Thanks again.

At least in Ubuntu 18.04, which I'm using, the desktop files should be in ~/.local/share/applications/

And correspondingly, for system wide packages, they are placed in /usr/share/applications/
