Last week I tried to update my Obsidian app from an Ubuntu machine and I got the following error message:
❯ sudo snap install obsidian_0.15.9_amd64.snap
error: cannot find signatures with metadata for snap
"obsidian_0.15.9_amd64.snap"A way to fix this issue is by using the --dangerous modifier.
❯ sudo snap install --dangerous obsidian_0.15.9_amd64.snap
obsidian 0.15.9 installed
