Hi, Andrea When I tried $ dget https://deb.debian.org/debian/pool/main/libv/libvirt/libvirt_8.5.0-1.dsc But failed, seems I did not have the public key? This is the message from my system: dget: using existing libvirt_8.5.0.orig.tar.xz dget: using existing libvirt_8.5.0.orig.tar.xz.asc dget: using existing libvirt_8.5.0-1.debian.tar.xz libvirt_8.5.0-1.dsc: dscverify: libvirt_8.5.0-1.dsc failed signature check: gpg: WARNING: no command supplied.

Hi, Andrea Thank you for your help, but I did not figure out how to deal with the dsc and rebuilding package stuff yet.
Also, I compiled and installed the libvirt-8.5.0 source code from https://libvirt.org/sources/. The build command I used is: meson build -Dsystem=true -Ddriver_interface=enabled -Ddriver_libvirtd=enabled -Ddriver_network=enabled -Ddriver_qemu=enabled -Ddriver_remote=enabled -Dnumactl=enabled -Dnumad=enabled -Dstorage_disk=enabled
Now my question is how to start the libvird? My OS is Ubuntu20. According to https://libvirt.org/compiling.html, when I tried # service libvirtd stop (or systemctl stop libvirtd.service), under build/src directory The system reports error: Failed to start/stop libvirtd.service: Unit libvirtd.service not found.
As I said in the previous message, I'd rebuild the Debian package instead of building from source. That way, you should be able to seamlessly replace the version of libvirt that you had installed from Ubuntu 20.04's repositories with a newer one.
The steps involved should be roughly
$ sudo apt-get update $ sudo apt-get install -y build-essential $ sudo apt-get build-dep -y libvirt
to install the necessary build dependencies, and then
$ dget https://deb.debian.org/debian/pool/main/libv/libvirt/libvirt_8.5.0-1.dsc $ cd libvirt-8.5.0/ $ dpkg-buildpackage --no-sign
to actually build the package. Assuming there are no errors, you should end up with a bunch of .deb files that you can install on the system using apt-get.
