Package: openssh-server Version: 1:7.9p1-10 Severity: important Dear Maintainer,
When running apt upgrade, openssh-server was left unconfigured after being upgraded to version 1:7.9p1-10. The configuration script output was as follows: ================= Setting up openssh-server (1:7.9p1-10) ... rescue-ssh.target is a disabled or a static unit, not starting it. Failed to restart ssh.service: Unit -.mount is masked. invoke-rc.d: initscript ssh, action "restart" failed. ● ssh.service - OpenBSD Secure Shell server Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2019-04-22 12:18:22 -03; 2 days ago Docs: man:sshd(8) man:sshd_config(5) Main PID: 960 (sshd) Tasks: 1 (limit: 4915) Memory: 3.1M CGroup: /system.slice/ssh.service └─960 /usr/sbin/sshd -D Apr 22 12:18:19 <%hostname%> systemd[1]: Starting OpenBSD Secure Shell server...

E: Sub-process /usr/bin/dpkg returned an error code (1) ================= Searching for this error did not return anything useful, but I realized that the issue was with restarting the ssh service. I found a workaround for this: disable the ssh service, run the upgrade, then re-enable the service. It still complains with: "Error: GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit -.mount is masked." But apart from that the service was restarted and everything is working again. -- Francisco -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (990, 'testing'), (800, 'unstable'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-4-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.utf8), LANGUAGE=en_US.utf8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.utf8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages openssh-server depends on: ii adduser 3.118 ii debconf [debconf-2.0] 1.5.71 ii dpkg 1.19.6 ii libaudit1 1:2.8.4-2 ii libc6 2.28-8 ii libcom-err2 1.44.5-1 ii libgssapi-krb5-2 1.17-2 ii libkrb5-3 1.17-2 ii libpam-modules 1.3.1-5 ii libpam-runtime 1.3.1-5 ii libpam0g 1.3.1-5 ii libselinux1 2.8-1+b1 ii libssl1.1 1.1.1b-2 ii libsystemd0 241-3 ii libwrap0 7.6.q-28 ii lsb-base 10.2019031300 ii openssh-client 1:7.9p1-10 ii openssh-sftp-server 1:7.9p1-10 ii procps 2:3.3.15-2 ii ucf 3.0038+nmu1 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages openssh-server recommends: ii libpam-systemd 241-3 ii ncurses-term 6.1+20181013-2 ii xauth 1:1.0.10-1 Versions of packages openssh-server suggests: ii ksshaskpass [ssh-askpass] 4:5.14.5-1 pn molly-guard <none> pn monkeysphere <none> pn rssh <none> pn ufw <none> -- debconf information: openssh-server/permit-root-login: true openssh-server/password-authentication: true
