This doesn't seem like it would work due to installerPath being a space-escaped string for piping to the cmd shell. Right?

If the platform is Linux, replace spaces with '\ ' for shell compatibility

electron-builder/packages/electron-updater/src/BaseUpdater.ts

Lines 52 to 60 in 6a6bed4

// Get the installer path, ensuring spaces are escaped on Linux
// 1. Check if downloadedUpdateHelper is not null
// 2. Check if downloadedUpdateHelper.file is not null
// 3. If both checks pass:
// a. If the platform is Linux, replace spaces with '\ ' for shell compatibility
// b. If the platform is not Linux, use the original path
// 4. If any check fails, set installerPath to null
const installerPath =
downloadedUpdateHelper && downloadedUpdateHelper.file ? (process.platform === "linux" ? downloadedUpdateHelper.file.replace(/ /g, "\\ ") : downloadedUpdateHelper.file) : null

Yes, I found that this was the cause, so I changed it to draft.

I don't think it's handled well here - it shouldn't directly add /. Instead, it should be handled by each deb/rpm/pacman separately.

These linux install commands use string concatenation, so if malicious code is added to the name, it could lead to serious security vulnerabilities.

electron-builder/packages/electron-updater/src/PacmanUpdater.ts

Lines 34 to 35 in 6a6bed4

const cmd = ["pacman", "-U", "--noconfirm", options.installerPath]
this.spawnSyncLog(sudo, [`${wrapper}/bin/bash`, "-c", `'${cmd.join(" ")}'${wrapper}`])

if (destination !== appImageFile) {
this.emit("appimage-filename-updated", destination)
}
