--- Begin Message ---Package: libc6 Version: 2.31-1 Severity: grave Justification: renders package unusable This is related to #965086 and #965087 (and, in fact, possibly causing them). After a glibc upgrade half the system services (postfix, sshd, apt-get(!)) don’t work any more. Downgrading with dpkg -i the following set of packages fixes it: libc-bin_2.30-8_x32.deb libc-dev-bin_2.30-8_x32.deb libc-l10n_2.30-8_all.deb libc6-dbg_2.30-8_x32.deb libc6-dev_2.30-8_x32.deb libc6_2.30-8_amd64.deb libc6_2.30-8_i386.deb libc6_2.30-8_x32.deb locales-all_2.30-8_x32.deb locales_2.30-8_all.deb unscd_0.53-1+b3_x32.deb Snippet from strace: […] 9839 getpid() = 9839 9839 chroot("/run/sshd") = 0 9839 chdir("/") = 0 9839 write(7, "\0\0\0$\0\0\0\7\0\0\0\34privsep user:group 1"..., 40) = 40 9839 setgroups(1, 0xffffffffff866750 <unfinished ...> 9794 <... poll resumed>) = 1 ([{fd=6, revents=POLLIN}]) 9839 <... setgroups resumed>) = -1 EFAULT (Bad address) 9794 read(6, <unfinished ...> 9839 write(7, "\0\0\0\36\0\0\0\1\0\0\0\26setgroups: Bad addre"..., 34 <unfinished ...> […] Noticeable: the sign-extended address.
