Public bug reported:
Package: spice-vdagent
Version: 0.23.0-1
Distribution: Ubuntu 26.04 LTS (resolute)
The systemd user unit shipped at
/usr/lib/systemd/user/spice-vdagent.service has the StandardError=null
directive placed under the [Install] section instead of [Service].
systemd ignores it (since StandardError is only valid in [Service]) and
logs a warning every time the unit is loaded:
systemd[7500]: /usr/lib/systemd/user/spice-vdagent.service:23:
Unknown key 'StandardError' in section [Install], ignoring.
The intent of the directive — per the comment immediately above it —
is to silence duplicated stderr/syslog output from spice-vdagent. That
intent is currently NOT being applied because the line is in the wrong
section.
Relevant excerpt (lines 18–23 of the shipped unit):
[Install]
WantedBy=graphical-session.target
# spice-vdagent logs via syslog() and to stderr, causing duplicated
# logs. Instead of sending stderr to the journal, disconnect it
StandardError=null
Fix: move the `StandardError=null` line (and the explanatory comment)
into the [Service] section, e.g. directly after `ExecStart=`.
The 0.23.0-1 changelog notes that several Debian patches were dropped
because they "applied upstream", including
`spice-vdagent-d-.service-Fix-duplicated-logs.patch`. The misplaced
section appears to have been introduced when that patch was folded in.
Impact: cosmetic only — a journal warning at every user-session start,
and the originally intended stderr suppression is silently disabled.
Reproduce:
systemd-analyze --user verify /usr/lib/systemd/user/spice-vdagent.service
