Re: windows x-xz-compressed-tar Unsupported compression options

Hello Phil,

 

thanks for reporting this. I was able to reproduce the bug and determine
that it was introduced in Zero Install for Windows 2.13.1. An incorrect
change to the .NET App.config files was causing the wrong version of the
.NET Runtime to be used, which in turned caused problems with the native
library used for XZ decompression.

 

I have just released Zero Install for Windows 2.14.2 which fixes this issue.

 

Regards

Bastian

Subject: [Zero-install-devel] windows x-xz-compressed-tar Unsupported
compression options

 

Bastian,

        There seems to be a bug in the tar.xz code in 2.14.0. I'm not sure
where between 2.13.0 and 2.14.0 it browk however.

When I try to load this archive
http://repo.msys2.org/msys/x86_64/msys2-runtime-2.7.0-1-x86_64.pkg.tar.xz
now it fails.

I was able to do this previously for this file. But I tried some other XZ
compressed files and got this error.

I deleted the cache for this file that previously worked. When zero install
extracts the archive it fails with the following error.

 

Unhandled Exception: System.Exception: Unsupported compression options
