/etc/machine-id contains 0 characters

Наблюдаю такую ошибку:

[19099:19099:0818/132537.104960:ERROR:browser_dm_token_storage_linux.cc(100)] Error: /etc/machine-id contains 0 characters (32 were expected)

Делаю:

cat /etc/machine-id
cat: /etc/machine-id: No such file or directory

Удивляюсь, иду гуглить.

Нахожу описание machine-id, внизу мелким шрифтом указано:

The simple configuration file format of /etc/machine-id originates in the /var/lib/dbus/machine-id file introduced by D-Bus. In fact, this latter file might be a symlink to /etc/machine-id.

Ясно всё.

# ln -s /var/lib/dbus/machine-id /etc/machine-id
