[Bug 1452698] [NEW] Issue in sahara-common.postinst.in: sahara-db-manage is executet on fresh install (even without a db-connection)
Public bug reported:
Hi there,
i dont know if this is the right place for this bug-report!?
But the following script-lines will execute sahara-db-manage, even on an
fresh install without any configured db-connection.
if ! grep -qE ^(sql_)?connection( )?=.* ${SAHARA_CONF} || \
grep -qE ^(sql_)?connection.*sqlite.* ${SAHARA_CONF}; then
su -s /bin/sh -c 'sahara-db-manage --config-file
/etc/sahara/sahara.conf upgrade head' sahara
fi
Becuse the default is:
#connection=None
and this matches the negated grep .
# lsb_release -rd
