How to include image and video files in assets

[ApurvaSolanki54]

I am packaging my application in deb file and there are some images and videos to include in deb file which I have included using assets like below in cargo.toml file but while installing I am getting error.

[package.metadata.deb]
assets = [
["webserver.jpg","/var/","777"],
["Video.mp4","/var/","777"],
["background_stat2.png","/var/","777"]
]

dpkg-deb (subprocess): decompressing archive member: lzma error: unexpected end of input

777 permission means it's an executable file.

But I'm surprised it complains about EOF. That doesn't seem to be related to file type at all.

I have also tried permission 664 but it gave me same error.

I'm getting the same thing with .tar.gz files included in my deb package.

cannot copy extracted data for 'opt/app/app-files-1.1.0.tar.gz' to '/opt/app/app-files-1.1.0.tar.gz.dpkg-new': unexpected end of file or stream

I'm starting to dig in to see what's going on.

So, I reinstalled using cargo install --no-default-features cargo-deb, and the re-generated deb file with this version installs without the decompression error. I'm guessing it's a bug in xz2.

can you try decompressing manually? ar -x the deb file to get data.tar.xz, and see if your system's unxz can decompress it?

I wonder if cargo-deb's library creates invalid or incompatible xz files.
