Not working at all under Pop OS 21.04

[Yuri6037]

Hi, I've just attempted to run appimage-builder on a Rust project which depends over 3 large system libs: libavcodec, libavformat and libswscale but it failed with that:

It seems that some packages changed their names from Ubuntu to Pop OS. Maybe you could try generating the recipe manually.

I'll investigate this as soon as I finish working on AppImageUpdate.

I think the issue is the gpg key no?

W: GPG error: http://ppa.launchpad.net/system76/pop/ubuntu hirsute InRelease: 
The following signatures couldn't be verified because the public key is not available:
 NO_PUBKEY 1E5F8BBC5BEB10AE

Could be, please check you have added the key url properly.

[Yuri6037]

Could be, please check you have added the key url properly.

This system in question is a clean Pop OS where apt works correctly and doesn't have any such key issue, this software is the only one to fail...

[goldstar611]

In your apt.sources check/add/update the key_url I have found several examples such as the following

apt:
 arch: i386
 sources:
   - sourceline: 'deb [arch=i386] http://mx.archive.ubuntu.com/ubuntu/ bionic main restricted universe multiverse'
     key_url: 'http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3b4fe6acc0b21f32'
#                                                                     ^^^^^^^^^^^^^^^^

Based on the error message, you'll need to update the key to 0x1E5F8BBC5BEB10AE
