I confirm the bug, and the nscd temp workaround. Same version. Wow, how'd you figure out that stopping nscd would help? For me, apt-get update/upgrade after stopping nscd fixes it permanently. There must have been a libc patch between when this was filed and now. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in
