Can't exec "kill": No such file or directory at /usr/bin/deb-systemd-invoke= line 179. Job for systemd-journald.service failed because the control process exited = with error code.

Could not execute systemctl: at /usr/bin/deb-systemd-invoke line 148. ----------------8<----------------8<----------------8<----------------- I can reproduce this locally with autopkgtest, like this: autopkgtest --no-built-binaries --apt-upgrade --add-apt-release=3Dunstable = --pin-packages=3Dunstable=3Dsrc:systemd debian-security-support -- incus a= utopkgtest/debian/testing/arm64 This is caused by an implicit dependeny on procps (for /usr/bin/kill). The code around deb-systemd-invoke line 179 is: 178 if ($is_system) { 179 system('kill', '-s', $signal, '1'); 180 } else { 181 system('systemctl', '--quiet', 'kill', '--kill-whom=3Dmain', '-= -signal', $signal, 'user@*.servic e'); 182 } The attached patch (against git master) fixes the issue, i.e. if I have the package with this patch installed, then upgrading systemd works. --QbbloiYil225KKAG Content-Type: text/x-diff; charset=us-ascii Content-Disposition: attachment; filename=0001-deb-systemd-invoke-don-t-assume-kill-is-available.patch Content-Transfer-Encoding: quoted-printable =46rom 9ef0e143ee5a68620f2bb98e68e6c3ee037620b3 Mon Sep 17 00:00:00 2001 =46rom: Antonio Terceiro <terceiro@debian.org> Date: Sat, 5 Sep 2026 13:46:50 -0300 Subject: [PATCH] deb-systemd-invoke: don't assume `kill` is available /usr/bin/kill is provided by procps, which is not a dependency, and might not be installed. For example, recent Debian CI containers do not include `procps`, and this revealed an implicit dependency in procps by init-system-helpers. Given Perl has a kill() function, we can just use that instead of shelling out to /usr/bin/kill. --- script/deb-systemd-invoke | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/script/deb-systemd-invoke b/script/deb-systemd-invoke index c94d47a..adfac93 100755 --- a/script/deb-systemd-invoke +++ b/script/deb-systemd-invoke @@ -371,7 +371,7 @@ sub reload_reexec_signal { } =20 if ($is_system) { - system('kill', '-s', $signal, '1'); + kill($signal, 1); } else { system('systemctl', '--quiet', 'kill', '--kill-whom=3Dmain', '--si= gnal', $signal, 'user@*.service'); } --=20 2.53.0 --QbbloiYil225KKAG-- --pbybjnID7TiudeqJ Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEst7mYDbECCn80PEM/A2xu81GC94FAmqcS2wACgkQ/A2xu81G C94+YRAA384DMktEYxOlsJ12d8/4hWWm6uwFIg+7BmtxmdHXkVqB2hFUNV0ZgNGS GX6/bp8zBL8WRzlChUg7DBhmd1sz2EIgwREHxRzfsO9cWMeK9UheWCPyX0W00Tb8 EcmekXCHz62Hw6Qtr63e6c28yjKk4Zb3JqmddH9fz3KNBeaXkxUgUBkpV0/dorA4 bndSXLd5wx90X3Xeo4+o8qz2zwa3PnGmoAscMe+fyQ7a8GTF7huZDgdPyA1cCyqs d80/ov8W0AVQ1zv8njUp3dIV0wiIaEhv25f8ZOq2IIeOPYgJUI0Cs73GeydyxOwd 7JI5AMEMzbWBrLWjk76tYu0S98dxv8JIcZltgGeY3A0znEK5wGA4qfcimLM7YG82 20sP5hCqbs8isXizbFwX96BZ3jXlQ1GaTkjsGv3AaM4nd3a+DBk7foHH9imvJDMc GxH67RcRlfUeMRxxauWsvX+RIZbz7kM/7P7byqJtjK3/J3BxMHMqmYo0Xs1ZxGI1 hFV8LpqD6oW8sydzDg507bHgB1jchQWP5FphVFjP3YntNP7Dxu6MNiJ9TiS7+PcN ki8/KNZbIgLIMDgCmJ1+7/ordJymloV7sg+Pze3TDDp9Zawe56HeWwOmwM0lULjf wDQefCyMa9qKREZDw7O+wCAc6btjuaQZJcKu8TkglcaNqeY2cj4= =DHJi -----END PGP SIGNATURE----- --pbybjnID7TiudeqJ-- ]
