`symbol lookup error` with the `.AppImage` on Ubuntu 19.04

[guillemcordoba]

Describe the bug

When executing the .AppImage compiled with Tauri on an Ubuntu 19.40, I get this error:

guillem@guillem:~/Baixades$ ./holochain-launcher_0.3.2_amd64.AppImage 
Gtk-Message: 00:03:55.561: Failed to load module "canberra-gtk-module"
Gtk-Message: 00:03:55.567: Failed to load module "canberra-gtk-module"
  /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitNetworkProcess: symbol lookup error: /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitNetworkProcess: undefined symbol: NetworkProcessMainUnix
/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess: symbol lookup error: /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess: undefined symbol: WebProcessMainUnix

And I get a blank window.

Error doesn't show up if I use a .deb package, so I assume it's related to the bundling process.

To Reproduce

Steps to reproduce the behavior:

1. Create a Tauri app.
2. Compile it inside an Ubuntu 18.04.
3. Try to execute the .AppImage in an Ubuntu 19.04.
4. See error

Expected behavior

The error doesn't happen.

Just for clarity sake, can you please share the data provided by tauri info

[guillemcordoba]

Yes yes sorry, was unclear if they were needed here, I updated the issue.

[amrbashir]

try this solution https://askubuntu.com/a/872397

[nothingismagick]

also, as an FYI - your rust is out of date. (pretty sure its not the problem here though)

> rustc --version
rust version 1.55.0 (c8dfcfe04 2021-09-06)

just run rustup update

[guillemcordoba]

Well I can't yet, there is a problem with some dependencies of the holochain crate that make it not compile in 1.55. But I have that noted down. @amrbashir I'll try it, thanks :D

[guillemcordoba]

@amrbashir doesn't solve the problem, although the initial warnings are not present anymore. Now what I get is:

guillem@guillem:~/Baixades$ ./holochain-launcher_0.3.3_amd64.AppImage 
/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitNetworkProcess: symbol lookup error: /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitNetworkProcess: undefined symbol: NetworkProcessMainUnix
/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess: symbol lookup error: /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess: undefined symbol: WebProcessMainUnix

I had the exact same error message as OP, but interestingly I received that error when building in a Centos 7.3.1611 docker image and deploying to the same OS version (not a container though).

This PR did fix it for me though (thanks @FabianLars !):
#2940

I experience the same error cargo tauri dev. when using the compiled appImage it works.
