can not deploy flannel - regression of snapd

The last release of snapd bring another a new bug .

The flannel charm use /usr/local/bin/ to deploy some binary

Because /usr/local/bin/ is not anymore in system-d PATH , all daemons does not have it .

so juju can not access it .

I reported the bug in snapd :

https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1814355

to fix:

wget http://archive.ubuntu.com/ubuntu/pool/main/s/snapd/snapd_2.34.2_amd64.deb
dpkg -i snapd_2.34.2_amd64.deb
init 6

wait a few minutes and juju can continue the deployment
