+# sos upgrade reproducer from bionic to xenial
+
+Download the xenial package using uvt
+
+```
+uvt-simplestreams-libvirt --verbose sync arch=amd64 release=xenial
+```
+
+Create the VM and ssh to it
+
+```
+uvt-kvm create xenial01 release=xenial --mem 1024
+uvt-kvm wait xenial01
+uvt-kvm ssh xenial01
+```
+
+Now, in the VM we run the following commands
+
+```
+sudo -i
+cat > /etc/update-manager/release-upgrades.d/allow-thirdparty.cfg << EOF
+[Sources]
+AllowThirdParty = yes
+EOF
+
+exit
+```
+
+```
+cat <<EOF >/etc/apt/sources.list.d/ubuntu-$(lsb_release -cs)-proposed.list
+# Enable Ubuntu proposed archive
+deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed restricted main multiverse universe
+EOF
+```
+
+
+
+```
+sudo apt -y update
+sudo apt -y upgrade
+
+sudo dpkg -l > pre-upgrade.txt
+
+sudo do-release-upgrade -f DistUpgradeViewNonInteractive
+
+sudo dpkg -l > post-upgrade.txt
+```
+
+Now, in a second VM
+
+```
+uvt-kvm create xenial02 release=xenial --mem 1024
+uvt-kvm wait xenial02
+uvt-kvm ssh xenial02
+```
+
+```
+cat <<EOF >/etc/apt/sources.list.d/ubuntu-$(lsb_release -cs)-proposed.list
+# Enable Ubuntu proposed archive
+deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed restricted main multiverse universe
+EOF
+```
+
+
+```
+sed -i s/xenial/bionic/g /etc/apt/sources.list
+sed -i s/xenial/bionic/g /etc/apt/sources.list.d/ubuntu-xenial-proposed.list
+```
+
