Exporting under Ubuntu 20.04 only seems to generate broken files

Right now, exporting .vtf-files under Ubuntu 20.04 (Sorry, haven't tried other distros) seems to be broken. Despite what setting i seem to try, it saves a 104-byte file that once loaded makes the editor complain about the image not being "a power of 2", but i suspect the whole file is broken, since my reference files are about 500-2000 KB.

I can't really provide any information on where the fault might be located but if the author or anyone else has some information on what causes this i would be grateful.

I have the same issue. My workaround is:

1. open and edit using GIMP
2. save as Targa
3. tga2vtf <infile.tga> <outfile.vtf>
4. A

I tried to export files in GIMP 2.10.18 after making this for the first time ever.
I got this error:
(file-vtf:41846): GLib-WARNING **: 01:57:32.384: (../../../glib/gerror.c:412):g_error_new_valist: runtime check failed: (domain != 0)

And then the files it was exporting only save as filesize 104 kb, every single time. I tried animated gifs, opening and exporting other people's VTFs, and like others suggested to save as TGA and export as VTF. None worked for me. It always goes out to a broken file.

I think you meant bytes
