Public bug reported: Stable release update justification:
[Impact] apt-ftparchive fails to produce .xz compressed files with sufficiently large data sets. This prevents migration of the Ubuntu archive to .xz. [Test Case] Grab trusty/main/amd64 with debmirror, construct a suitable file list, and ask apt-ftparchive to generate files for this with Packages::Compress set to include xz. We can easily test this on the Launchpad "dogfood" instance where we do QA of the archive publisher. [Regression Potential] Confined to lzma/xz compression, which I think is basically just apt-ftparchive, but we should make sure that other compression methods still work there. Original report follows: Imported from Debian bug http://bugs.debian.org/751688: Package: apt-utils Version: 0.9.15.5 Severity: normal Dear Maintainer, Tested with 1.0.4 and reinstalled working 0.9.15.5 Packages::Compress seems to not work anymore with xz compression. Only . (uncompressed), gzip and bzip2 seems to work, xz now return errors (see at the bottom).
