Repro: 1. Have the sqlite USE flag unset for dev-lang/python 2. Build fail2ban 3. Run fail2ban Result: fail2ban fails with this log message: fail2ban.server [24941]: ERROR Unable to import fail2ban database module as sqlite is not available. Fix: re-emerge pyhton with the sqlite USE flag.

This bit of advice has been around since forever: if ! has_version dev-lang/python[sqlite]; then elog "If you want to use ${PN}'s persistent database, then reinstall" elog "dev-lang/python with USE=sqlite" fi Depending on your local configuration, the USE dependency may or may not be used: /etc/fail2ban/fail2ban.conf: # Options: dbfile # Notes.: Set the file for the fail2ban persistent data to be stored. # A value of ":memory:" means database is only stored in memory # and data is lost when fail2ban is stopped. # A value of "None" disables the database. # Values: [ None :memory: FILE ] Default: /var/lib/fail2ban/fail2ban.sqlite3 dbfile = /var/lib/fail2ban/fail2ban.sqlite3
