The downstream Ubuntu report, in particular, contains a lot of useful context. It seems fairly certain that this is the same bug. -- System Information: Debian Release: 13.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 6.12.94+deb13-cloud-amd64 (SMP w/1 CPU thread; PREEMPT) Locale: LANG=C.UTF-8, 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 pcp depends on: ii gawk 1:5.2.1-2+b1 ii libbpf1 1:1.5.0-3 ii libc6 2.41-12+deb13u3 ii libelf1t64 0.192-4 ii libncursesw6 6.5+20250216-2 ii libpcp-archive1 6.3.8-1 ii libpcp-gui2 6.3.8-1 ii libpcp-import1 6.3.8-1 ii libpcp-mmv1 6.3.8-1 ii libpcp-pmda3 6.3.8-1 ii libpcp-trace2 6.3.8-1 ii libpcp-web1 6.3.8-1 ii libpcp3 6.3.8-1 ii libpfm4 4.13.0+git99-gc5587f9-1 ii libreadline8t64 8.2-6 ii libssl3t64 3.5.6-1~deb13u2 ii libtinfo6 6.5+20250216-2 ii libuv1t64 1.50.0-2 ii pcp-conf 6.3.8-1 ii procps 2:4.0.4-9 ii python3 3.13.5-1 ii python3-pcp 6.3.8-1 ii zlib1g 1:1.3.dfsg+really1.3.1-1+b1 Versions of packages pcp recommends: ii libpcp-pmda-perl 6.3.8-1 Versions of packages pcp suggests: pn bpftrace <none> pn libpcp-import-perl <none> pn pcp-gui <none> pn python3-bpfcc <none> ii redis-server 5:8.0.2-3+deb13u2 ii zstd 1.5.7+dfsg-1 -- no debconf information
