My setup is perhaps somewhat unusual. It is totally disconnected from the internet. I use the sneakernet method to import things from the internet.
At the moment I’m running LXD 4.14 (snap). My question: can I manually install a (downloaded) LXD 5.0 snap onto a running LXD 4.14? Is that upgrade handled gracefully?
Also important to mention, this is a cluster with 6 hosts. Do I need to shutdown all 6 hosts before installing that LXD 5.0 snap on each of them?
Related to this. I’ve searched everywhere, but it seems impossible to find old LXD snaps. As soon as the snapstore gets a new LXD channel version all prior snaps are gone. Surely they must be somewhere, but unavailable on the public internet. I really don’t understand why that is. (This is probably a “design” choice of snapcraft, but what purpose does that have?)
