If apt-listbugs is installed in a system then, when there are problems with IPv6, "apt install/update" can appear to hang at "Retrieving bug reports...0%" Requires ctrl-C, and after saying do not try to retrieve bugs again apt asks if it should continue installation. When I select "yes" it then fails to continue installation. Also "apt-listbugs -d list apt-listbugs" initally reports: Exception `LoadError' at :136 - cannot load such file -- soap/rpc/driver Exception `LoadError' at :136 - cannot load such file -- xml/encoding-ja Exception `LoadError' at :144 - cannot load such file -- xml/encoding-ja Set XSD::XMLParser::XMLParser as XML processor. Exception `LoadError' at :136 - cannot load such file -- httpclient Exception `LoadError' at :136 - cannot load such file -- addressable/uri Exception `LoadError' at :144 - cannot load such file -- addressable/uri Exception `KeyError' at /usr/lib/ruby/vendor_ruby/http/cookie_jar/abstract_store.rb:15 - key not found: :hash and then gets to... "! CONNECT TO bugs.debian.org 80" (Debian 12) at which point it seems to hang. But if I wait for over 6 MINUTES then it does seem to fall back to IPv4 to get the details. So perhaps my subject line is wrong, but the timeouts are obviously too long and, coupled with the multiple redirects, means nobody is going to wait that long unless they've gone off for a coffee. The cause of the problem is that my ISP broke routing for my IPv6 address a week ago, but it was not immediately obvious and is still not fixed. workaround: is to either uninstall apt-listbugs, or temporarily disable IPv6 (if convenient). In either case apt then works quickly. -- System Information: Debian Release: 13.0 APT prefers testing-security APT policy: (500, 'testing-security'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 6.12.33+deb13-amd64 (SMP w/1 CPU thread; PREEMPT) Locale: LANG=C, LC_CTYPE=C.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-listbugs depends on: ii apt 3.0.3 ii distro-info 1.13 ii ruby 1:3.3+b1 ii ruby-debian 0.3.10+b13 ii ruby-gettext 3.4.9-1 ii ruby-soap4r 2.0.5-9 ii ruby-unicode 0.4.4.5-1+b2 ii ruby-xmlparser 0.7.3-6+b1 Versions of packages apt-listbugs recommends: ii ruby-httpclient 2.8.3+git20211122.4658227-1 ii ruby-sys-proctable 1.3.0-1 Versions of packages apt-listbugs suggests: ii reportbug 13.2.0 ii sensible-utils 0.0.25 pn w3m | www-browser pn xdg-utils -- no debconf information
