Description Xavier Corredor Llano 2020-11-11 01:06:23 UTC

Hey folk,

I cannot decompress a zip file (only by terminal), Ark says:

> There was an error while extracting ‘GFDLCM3_scaled.zip’:
> Failed to open 'GFDL_CM3_scaled/g_clim_res.tfw': Compression method not supported

in terminal (failed):


> $ unzip GFDLCM3_scaled.zip
> Archive:  GFDLCM3_scaled.zip
> skipping: GFDL_CM3_scaled/g_clim_res.tfw  need PK compat. v6.3 (can do v4.6)
> skipping: GFDL_CM3_scaled/g_clim_res.tif  need PK compat. v6.3 (can do v4.6)
> ....

in terminal (works):

> $ 7z x GFDLCM3_scaled.zip

File for testing:

Using Archlinux with Ark v20.08.3

Confirmed on KDE Neon Unstable, same error.

Please make sure you have p7zip installed and have p7zip plugin enabled in Ark settings.

The test file uses LZMA, which is not supported by unzip plugin.

By the way, libzip plugin should probably be disabled in this case, otherwise Ark will use libzip and fail to decompress the file.

libzip's LZMA support should be available in the next release. If you want to use libzip to decompress the test file, you will need to compile libzip from git and patch Ark.
