I was just trying to install a snap and it bombed out mid way - this is my session:
laney@nightingale> snap install code --classic error: cannot perform the following tasks: - Fetch and check assertions for snap "code" (23) (Get https://api.snapcraft.io/api/v1/snaps/assertions/snap-revision/_BSGjykfN60hxNeIl3PEjlr_CWe9tIui1CTxaqXoLuqwylMOumRrdPUA_R9lNiuy?max-format=0: dial tcp: lookup api.snapcraft.io: no such host) laney@nightingale> snap install code --classic code 26076a4d from Visual Studio Code (vscode✓) installed laney@nightingale> snap version snap 2.42.5 snapd 2.42.5 series 16 ubuntu 20.04 kernel 5.3.0-23-generic
There’s a couple of things here that could maybe be improved:
- That DNS failure was transient. Would it be possible to retry fetches like this?
- When I issued the second
snap install, the same snap was fetched again. I’m on tethered (metered) data, so this could be expensive as well as slow. It’s 144MB! How about some limited caching?
