SU installation failed due to insufficient permissions

WMallik · June 5, 2020, 16:16

Hello,

I am having trouble to install SU2 7.05 on Ubuntu20.04 by compiling from the source code. I am trying to follow the instructions on their website. The meson build command with the additional options works well. But then as I try to build install with ninja I am facing a problem.

My command:
$ ./ninja -C build install
ninja: Entering directory `build'
[869/870] Installing files.
Installing SU2_CFD/src/SU2_CFD to /usr/local/bin
Installation failed due to insufficient permissions.
Attempting to use polkit to gain elevated privileges...
Error getting authority: Error initializing authority: Could not connect: No such file or directory
FAILED: meson-install
/usr/bin/python3 /home/wrik/SU2/meson.py install --no-rebuild
ninja: build stopped: subcommand failed.

I am no expert in Linux. Not sure why this is happening. Any help would be appreciated!

You have to choose an installation directory with `--prefix` option when you call meson. Otherwise it tries to install it to /usr/local/bin, which requires root privileges.
