I use Ubuntu 22.04, and installed from the PPA according to the install pages. And even though the software itself installed seemingly correctly, the libraries did not. I have no symbols whatsoever.
Just to make sure, I repeated the installation procss by typing apt install kicad kicad-libraries kicad-doc-en kicad-demos unixodbc extra-xdg-menus
(i.e., kicad as well as all “recommends” and “suggests”).
In KiCad, under Preferences, the variable KICAD8_SYMBOL_DIR points to /usr/share/kicad/symbols.
That directory does not exist. Not just empty, completely non-existant.
Typing dpkg -L kicad-libraries
shows this:
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/kicad-libraries
/usr/share/doc/kicad-libraries/changelog.gz
And downloading the kicad-libraries file gave me a 1176 byte large file named “kicad-libraries_8.0.6~ubuntu22.04.1_all.deb”.
I also installed the Windows version (downloaded the install .exe file), and it looks like the files under C:\Program Files\KiCad\8.0\share\kicad match what is under /usr/share/kicad in Ubuntu.
The Windows version had a “symbol” directory with 223 entires, and also “3dmodels” and “footprints” directories.
