(It's not solving the problem. Just a record.)
For unknown reason my wireshark is complaining the following:
Error Traversing Database for ipnum = XXXXXX - Perhaps database is corrupt?
#2207 (Issue with Geo Location) – Deluge
I have replace the geoip-database package with geoip-database-contrib and the problem seems to be resolved.
Install geoip-database-contrib require removing geoip-database and geoip-database-extra. After this the wireshark complain about the following:
Error Opening file /usr/share/GeoIP/GeoIPASNumv6.dat Error Opening file /usr/share/GeoIP/GeoIPASNum.dat Error Opening file /usr/share/GeoIP/GeoLiteCityv6.dat Error Opening file /usr/share/GeoIP/GeoLiteCity.datIt's not solving the problem, so I reverted to the original.
