How To Tell Which Repository a Package Comes From Debian Mint Ubuntu

Just use apt-cache policy to find the repo of a package:

apt-cache policy lxd
lxd: Installed: 3.0.3-0ubuntu1~18.04.2 Candidate: 3.0.3-0ubuntu1~18.04.2 Version table: *** 3.0.3-0ubuntu1~18.04.2 500 500 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 100 /var/lib/dpkg/status 3.0.0-0ubuntu4 500 500 http://archive.ubuntu.com/ubuntu bionic/main amd64 Packages

Or use apt show

apt show lxd Package: lxd Version: 3.0.3-0ubuntu1~18.04.2 Built-Using: golang-1.10 (= 1.10.4-2ubuntu1~18.04.2) Priority: optional Section: admin Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com> Bugs: https://bugs.launchpad.net/ubuntu/+filebug Installed-Size: 20.6 MB Depends: acl, adduser, dnsmasq-base, ebtables, iproute2, iptables, liblxc1 (>= 2.1.0~), lsb-base (>= 3.0-6), lxcfs, lxd-client (= 3.0.3-0ubuntu1~18.04.2), passwd (>= 1:4.1.5.1-1ubuntu5~), rsync, squashfs-tools, uidmap (>= 1:4.1.5.1-1ubuntu5~), xdelta3, xz-utils, libacl1 (>= 2.2.51-8), libc6 (>= 2.14), libuv1 (>= 1.4.2) Recommends: apparmor Suggests: criu, lxd-tools Homepage: https://linuxcontainers.org/ Task: cloud-image, server Supported: 5y Download-Size: 5,199 kB APT-Manual-Installed: yes APT-Sources: http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages Description: Container hypervisor based on LXC - daemon LXD offers a REST API to remotely manage containers over the network, using an image based workflow and with support for live migration. .
