Fix failed to bundle project: error running appimage.sh on ubuntu

[jaca1119]

Not sure if this is place for this so feel free to move it somewhere else.

In my case issue was downloading file linuxdeploy-plugin-gtk.sh

Problem

failed to bundle project: error running appimage.sh

Diagnosis

First of all check verbose output of tauri build in my case npm run tauri build -- --verbose (npm require this -- signs)

In my case line before error was

+ wget -q -4 -N https://raw.githubusercontent.com/tauri-apps/linuxdeploy-plugin-gtk/master/linuxdeploy-plugin-gtk.sh
       Error [tauri_cli_node] failed to bundle project: error running appimage.sh

Testing wget verbose output wget -v -4 -N https://raw.githubusercontent.com/tauri-apps/linuxdeploy-plugin-gtk/master/linuxdeploy-plugin-gtk.sh
Output

ERROR: cannot verify raw.githubusercontent.com's certificate
  Unable to locally verify the issuer's authority.
ERROR: no certificate subject alternative name matches
	requested host name ‘raw.githubusercontent.com’

Solution

Not sure it it's best solution but I found answer here -> https://superuser.com/a/1734923

Update certificates (copy from link)

 sudo apt install --reinstall ca-certificates

 sudo update-ca-certificates -f

I'm not sure what these lines exactly do but it solved my issue so do it at your own risk.
