I am currently working on a project which involves talking to the
|
|
|
|
|
`systemd` userspace session via the session `dbus` instance.
|
|
|
|
|
|
|
|
|
|
After some fiddling around and enabling debug mode on travis via the
|
|
|
|
|
excellent user support, I came up with the following.
|
|
|
|
|
|
|
|
|
|
Travis uses VMs that run `ubuntu` which comes with `systemd`. To
|
|
|
|
|
enable the userspace `dbus` session, one has to install the
|
|
|
|
|
`dbus-user-session` package. After the installation, it has to be
|
|
|
|
|
activated through `systemctl --user start dbus`. Furthermore one has
|
|
|
|
|
to set the `DBUS_SESSION_BUS_ADDRESS` environment variable through
|
|
|
|
|
`export DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/$(id -u)/bus`.
|
|
|
|
|
|
|
|
|
|
TL;DR
|
|
|
|
|
|
|
|
|
|
```yaml
|
|
|
|
|
script:
|
|
|
|
|
- sudo apt update
|
|
|
|
|
- sudo apt install dbus-user-session
|
|
|
|
|
- systemctl --user start dbus
|
|
|
|
|
- export DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/$(id -u)/bus
|
|
|
|
|
```
