Pironman5 service produces permission denied errors

[y-vectorfield]

Description

After fresh installation on Ubuntu 24.04 (Noble Numbat), pironman5 service
produces permission denied errors when InfluxDB tries to access data directory.

Error Log

[ERROR] Failed to set data: {"error":"not attempting to open shard 14; opening shard previously failed with: [shard 14] failed opening /var/lib/influxdb/data/pironman5-max/default_policy/14/fields.idx: open /var/lib/influxdb/data/pironman5-max/default_policy/14/fields.idx.tmp: permission denied"}

Workaround

sudo chmod 755 /var/lib/influxdb/
sudo systemctl restart pironman5.service

Root Cause

install.sh does not set appropriate permissions for /var/lib/influxdb directory.
Since pironman5.service runs as root, it cannot write to InfluxDB data.

Solution

Add permission setup in install.sh post-install section to ensure
/var/lib/influxdb is writable by root user.
