Some time ago, Arch developers transitioned from udev to systemd-tools. I’m a Firefox user but I also use sometimes Google Chrome or Konqueror/Rekonq because I have other accounts configured on them.
I didn’t open Chrome for a while now, and when I tried to open it, It didn’t launched. After execute it on the CLI, I saw the following message:
/usr/bin/google-chrome: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory
As you can see, it did not found libudev.so.0 because the upgrade mentioned before. As dirty hack, you can create a soft link to your latest libudev.so. In my case, as root:
# ln -sf /usr/lib/libudev.so.1.0.3 /usr/lib/libudev.so.0
As you may already guessed, you first have to see your installed version with:
$ ls -la /usr/lib/libudev.so*
