"gnome-tweak-tool: command not found" after installation
In Ubuntu 18.04 aka Bionic Beaver the gnome-tweak-tool
is a transitional package which is used to pull in a different package, in your case gnome-tweaks
to make upgrades more smooth when a package name had to be renamed. For whatever reasons...
You can see this information when using apt-cache show gnome-tweak-tool
. The Depends:
line is the package that is pulled in.
So to run it, just enter gnome-tweaks
or use dpkg -L gnome-tweaks
to list the files that are shipped with that package.
