Ok... mate-applets package builds and installs now, but looks like the real problem is that the cpufreq applet is being linked to the versioned library (instead of libcpupower.so or libcpupower.so.1).
$ ldd /usr/lib/mate-applets/mate-cpufreq-applet | grep cpupower libcpupower.so.4.13.0-32 => /usr/lib/libcpupower.so.4.13.0-32 (0x00007f04df4a6000) In Debian it looks better: $ ldd /usr/lib/mate-applets/mate-cpufreq-applet | grep cpupower libcpupower.so.1 => /usr/lib/libcpupower.so.1 (0x00007f5e94357000) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1215411 Title: libcpupower.so is not installed from linux-tools Status in linux package in Ubuntu: In Progress Status in linux source package in Zesty: In Progress Bug description: The patch for bug 1158668 installs cpupower_$(abi_version) command- line tool as well as libcpupower.so.$(abi_version). This isn't particularly suitable for projects that previously used libcpufreq and intend to migrate to libcpupower, because the libcpupower.so symlink is no longer installed. The command-line tools can also have symlinks (e.g. cpupower -> cpupower_$(abi_version)).
