singular/armhf is missing because it build-depends on polybori, which FTBFS on armhf with a segfault in python2.7.
gdb backtrace of this segfault shows: #0 0xb6a9b408 in ?? () from /lib/arm-linux-gnueabihf/libcrypto.so.1.0.0 #1 0xb6a98d30 in OPENSSL_cpuid_setup () from /lib/arm-linux-gnueabihf/libcrypto.so.1.0.0 #2 0xb6fe28bc in call_init (l=<optimized out>, argc=argc@entry=3, argv=argv@entry=0xbefff724, env=env@entry=0xbefff734) at dl-init.c:72 #3 0xb6fe2996 in call_init (env=<optimized out>, argv=<optimized out>, argc=<optimized out>, l=<optimized out>) at dl-init.c:30 #4 _dl_init (main_map=0x377378, main_map@entry=0xb6c1db60, argc=3, argv=0xbefff724, env=0xbefff734) at dl-init.c:120 #5 0xb6fe59b6 in dl_open_worker (a=<optimized out>) at dl-open.c:575 #6 0xb6fe27f4 in _dl_catch_error (objname=0xbeffde9c, objname@entry=0xbeffdeb4, errstring=0xbeffdea0, errstring@entry=0xbeffdeb8, mallocedp=0xbeffde9b, mallocedp@entry=0xbeffdeb3, operate=0xb6fe574d <dl_open_worker>, args=0xbeffdea4, args@entry=0xbeffdebc) at dl-error.c:187 #7 0xb6fe5450 in _dl_open ( file=0x376370 "/usr/lib/python2.7/lib-dynload/_hashlib.arm-linux-gnueabihf.so", mode=-2147483646, caller_dlopen=0xb05e9 <_PyImport_GetDynLoadFunc+196>, nsid=<optimized out>, argc=3, argv=0xbefff724, env=0xbefff734) at dl-open.c:660 #8 0xb6eb4ab8 in dlopen_doit (a=0xbeffe100) at dlopen.c:66 #9 0xb6fe27f4 in _dl_catch_error (objname=0x379764, errstring=0x379768, mallocedp=0x379760, operate=0xb6eb4a65 <dlopen_doit>, args=0xbeffe100) This looks like either a bug in openssl on armhf, which is important to fix (unblocking polybori and singular); or a bug in polybori on all architectures which happens to trigger a crash on armhf but not on other architectures, so should be fixed in polybori. Either way, binary removal of singular/armhf does not look like the right answer to me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1595485 Title: packages to remove from yakkety To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flightgear/+bug/1595485/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
