[ 20.704584] systemd[1]: Initializing machine ID from D-Bus machine ID.[ 20.916182] systemd-journald[2136]: Failed to open runtime journal: Invalid argument
You need to look at at least two files, /var/lib/dbus/machine-id and /etc/machine-id . They should contain only a 128-bit hexadecimal number plus a newline, and this number must match the number used in the directory names below /run/log/journal/ and /var/log/journal/ .
