Both the iso-image file openSUSE-10.3-GM-DVD-i386.iso and the delta iso openSUSE-10.3-RC1_GM-DVD-i386.delta.iso are assumed good by the match of their md5sums. rpm --query --info deltarpm shows version 3.4 rel 36 (as expected) However when attempting to run the applydeltaiso command the following error occurs: applydeltaiso SU10.3.i386/openSUSE-10.3-GM-DVD-i386.iso SU10.3.RC1.i386.delta/openSUSE-10.3-RC1_GM-DVD-i386.delta.iso new.openSUSE-10.3-GM-DVD-i386.iso reading 363151280 bytes from old iso...done 3ddiag.i586 (bzip): applying delta payload uncompress error bytes read = 14056, expected bytes = 56014 The source code applydeltaiso.c around line 181ff reads: opcf = cfile_open(CFILE_OPEN_RD, CFILE_IO_FILE, fpold, CFILE_COMP_XX, nmp[i], 0, 0); if (!opcf) { fprintf(stderr, "payload open failed\n"); exit(1); } dod = opcf->read(opcf, paydata, paylen); if (dod != paylen) { fprintf(stderr, "payload uncompress error\n"); fprintf(stderr, "bytes read = %d, but expected %d\n", dod, paylen); /* added for debugging */ exit(1); } I am assuming the following: (1) iso image is good by md5sum (2) delta iso likewise (3) deltarpm ver/rel is okay (via Yast2 install software) But the error indicates problems with data compression. Could the iso-image have a different type of compression than what is expected? So is this a genuine bug? I hope I am not forced to use jigdo to update my 10.3 iso image Any suggestions? I am inclined to report this as a bug, I do need to update the 10.3 isoimage (last time I had to reinstall, it took 8 hours just to apply the online update patches) - Randall -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
