So... the modified SONAME is apparently needed for the specific version of cpupower tool to depend strictly on the corresponding version of libcpupower.so.* from the same linux-tools-* package:
$ objdump -p /usr/lib/libcpupower.so.4.15.0-10 | grep SONAME SONAME libcpupower.so.4.15.0-10 $ ldd /usr/lib/linux-tools-4.15.0-10/cpupower | grep libcpupower libcpupower.so.4.15.0-10 => /usr/lib/libcpupower.so.4.15.0-10 (0x00007fb94ec4b000) $ dpkg -S /usr/lib/linux-tools-4.15.0-10/cpupower linux-tools-4.15.0-10: /usr/lib/linux-tools-4.15.0-10/cpupower $ dpkg -S /usr/lib/libcpupower.so.4.15.0-10 linux-tools-4.15.0-10: /usr/lib/libcpupower.so.4.15.0-10 With such setup, it won't be possible to make mate-cpufreq-applet link against a symlink (like libcpupower.so.1) instead of the versioned library (like libcpupower.so.4.15.0-10). I really don't know how to solve this without breaking that setup. Anyone has any ideas? -- 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)).
