Comment 13 for bug 1995469

Workaround to manually install the python3-pyroute2 packages from the Archive tracker on Jammy-Zed seems to fix temporarily the issue as well

To download the packages from one machine with Zed repository enabled on Jammy :

for package in $(apt search python3-pyroute2 2>/dev/null | grep installed | cut -f 1 -d '/'); do apt download $package; done
$ ls pyroute2/ -l
total 432

Install all the following packages on all nova-computes :
for i in {0..2}; do juju scp -- -r ./pyroute2 $i:~/ ; juju ssh $i sudo dpkg -i ./pyroute2/* ; done
juju run -a nova-compute systemctl restart neutron-ovn-metadata-agent.service
