Package: apt-cacher-ng Version: 3.6-1 Severity: normal I have a fairly generic apt-cacher-ng configuration that I use for sbuild. (The only configuration I've changed is to add BindAddress: localhost and change the Debian backend to https://deb.debian.org/debian/) Relatively recently I've noticed sbuild update failing with some regularity with the following error:
source:buster-i386-sbuild: Performing update. Err:1 http://localhost:3142/debian buster InRelease 502 Mirror blocked due to repeated errors [IP: ::1 3142] Restarting apt-cacher-ng clears up this problem and then sbuild update works as normal. This might (or might not; it happens a few minutes earlier than this error) be correlated with the following error message: Feb 17 09:17:16 gwaihir apt-cacher-ng[833]: [warn] Call to getaddrinfo_async with no evdns_base configured. Feb 17 09:17:19 gwaihir apt-cacher-ng[833]: [warn] Call to getaddrinfo_async with no evdns_base configured. Feb 17 09:17:21 gwaihir apt-cacher-ng[833]: [warn] Call to getaddrinfo_async with no evdns_base configured. It's more strongly correlated with this error that's logged in /var/log/apt-cacher-ng/apt-cacher.err: Mon Feb 15 09:19:50 2021|Failure to create replacement of debrep/dists/stretch/InRelease - CHECK FOLDER PERMISSIONS! Mon Feb 15 09:19:50 2021|Failure to create replacement of debrep/dists/stretch/Release - CHECK FOLDER PERMISSIONS! There doesn't seem to be anything odd about the permissions of those directories under /var/cache/apt-cacher-ng. They're all owned by apt-cacher-ng:apt-cacher-ng and are mode 2755. Probably related, temporary working files seem to be left behind in /var/cache/apt-cacher-ng/debrep/dists sometimes (but not for every occurence of this error): buster: InRelease InRelease.head InRelease1613585303 contrib/ main/ non-free/ sid: InRelease InRelease.head contrib/ main/ non-free/ These files, when they appear, are zero-length. -- Package-specific info: -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (990, 'unstable'), (500, 'unstable-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-3-amd64 (SMP w/12 CPU threads) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages apt-cacher-ng depends on: ii adduser 3.118 ii debconf [debconf-2.0] 1.5.74 ii dpkg 1.20.7.1 ii libbz2-1.0 1.0.8-4 ii libc6 2.31-9 ii libevent-2.1-7 2.1.12-stable-1 ii libevent-pthreads-2.1-7 2.1.12-stable-1 ii libgcc-s1 10.2.1-6 ii liblzma5 5.2.5-1.0 ii libssl1.1 1.1.1i-3 ii libstdc++6 10.2.1-6 ii libsystemd0 247.3-1 ii libwrap0 7.6.q-31 ii lsb-base 11.1.0 ii zlib1g 1:1.2.11.dfsg-2 Versions of packages apt-cacher-ng recommends: ii ca-certificates 20210119 Versions of packages apt-cacher-ng suggests: pn avahi-daemon <none> pn doc-base <none> ii libfuse2 2.9.9-3 -- Configuration Files: /etc/apt-cacher-ng/security.conf [Errno 13] Permission denied: '/etc/apt-cacher-ng/security.conf' -- debconf information: apt-cacher-ng/cachedir: keep apt-cacher-ng/proxy: keep apt-cacher-ng/port: keep apt-cacher-ng/bindaddress: keep * apt-cacher-ng/tunnelenable: false apt-cacher-ng/gentargetmode: No automated setup
