When creating an ELF dataset without choosing a specific packer, the following issue occurs :

@smarbal this error shows a trace of UPX 4.01 while being handling Pakkero, meaning that this last one relies on UPX and does not support its latest version. I opened an issue here. Conclusion: Pakkero is broken ; I will disable it in packers.yml
