Did the project change in some way or was it the packaging environment that changed? I'd like to know a bit more details even if the solution below works to determine if this was a regression in CPack or something else. > This is the output of debian package manager: > > dpkg: warning: downgrading lyx24 from 2.4.0-50424git-g3a4b233 to > 2.4.0-50422git-gd6fb2ab > (Reading database ... 422667 files and directories currently > installed.) > Preparing to unpack lyx24-2.4.0-50422git-Linux.deb ... > Unpacking lyx24 (2.4.0-50422git-gd6fb2ab) over > (2.4.0-50424git-g3a4b233) ... > dpkg: error processing archive lyx24-2.4.0-50422git-Linux.deb > (--install): > corrupted filesystem tarfile - corrupted package archive > dpkg-deb: error: subprocess paste was killed by signal (Broken > pipe) > Errors were encountered while processing: > lyx24-2.4.0-50422git-Linux.deb > > Analysing the data.tar.gz gives no hint.

If I'm right you could: 1) shorten the file paths in the archive 2) use gnu tar instead by setting CPACK_DEBIAN_ARCHIVE_TYPE to gnutar See https://cmake.org/cmake/help/v3.10/module/CPackDeb.html#variable:CPACK_DEBIAN_ARCHIVE_TYPE Regards, Domen
