If you use BIND and your system is not configured to use IPv6 then you will see the following annoying messages in your /var/log/syslog file:
named[13269]: error (network unreachable) resolving 'uk/DS/IN': 2001:500:1::803f:235#53
To resolve this you need to pass the "-4" option to /usr/sbin/named daemon.
The bind9 package historically used the /etc/default/bind9 file to allow you to configure custom options for the service.
However, Debian Jessie now uses systemd and because, unfortunately, the bind9 package maintainers did not do a good job adapting to this change, your only option for the time being seems to be to edit the /lib/systemd/system/bind9.service file to add the "-4" option and then run:
systemctl daemon-reload
service bind9 restart
It is possible that this process will need to be repeated if bind9 package is updated.
Similar instructions apply to Ubuntu LTS

| # cache_dir is used to set the location of the local cache. This can # become quite large, so make sure it is somewhere with plenty of space. cache_dir=/var/cache/apt-cacher # worried about unauthorised machines fetching packages through it, you can # specify a list of IPv4 addresses which are allowed to use it and another # list of IPv4 addresses which aren't. # Localhost (127.0.0.1) is always allowed. Other addresses must be matched # by allowed_hosts and not by denied_hosts to be permitted to use the cache. # Setting allowed_hosts to "*" means "allow all". # Otherwise the format is a comma-separated list containing addresses, # optionally with masks (like 10.0.0.0/22), or ranges of addresses (two # addresses separated by a hyphen, no masks, like '192.168.0.3-192.168.0.56'). allowed_hosts=10.1.1.0/24 an das eigene Netz anpassen ! denied_hosts= # Apt-cacher can generate usage reports every 24 hours if you set this # directive to 1. You can view the reports in a web browser by pointing # to your cache machine with '/apt-cacher/report' on the end, like this: # http://yourcache.example.com/apt-cacher/report # Generating reports is very fast even with many thousands of logfile # lines, so you can safely turn this on without creating much # additional system load. generate_reports=1 # Apt-cacher can clean up its cache directory every 24 hours if you set # this directive to 1. Cleaning the cache can take some time to run # (generally in the order of a few minutes) and removes all package # files that are not mentioned in any existing 'Packages' lists. This # has the effect of deleting packages that have been superseded by an # updated 'Packages' list. clean_cache=1 # apt-cacher can use different methods to decide whether package lists need to # be updated, # A) looking at the age of the cached files # B) getting HTTP header from server and comparing that with cached data. This # method is more reliable and avoids desynchronisation of data and index files # but needs to transfer few bytes from the server every time somebody requests # the files ("apt-get update") # Set the following value to the maximum age (in hours) for method A or to 0 # for method B expire_hours=0 |
Damit Ihr Cache von Zeit zur Zeit automatisch "aufgeräumt" wird, ist es sinnvoll, die "clean_cache" -Variable zu setzen. Welche Methode dabei für Sie die geeigneteste ist, sollten Sie mit einem Testlauf ausprobieren.
# set to 1 to start the daemon at boot time

Wenn Sie den Default-Cacher-Port verändern wollen:
# EXTRAOPT=" daemon_port=3142 limit=30 "

Hi out there,
you like to install your Orcale Virtualbox but running into something pyhton related like this ?:
sudo dpkg -i virtualbox-6.1_6.1.10-138449\~Ubuntu\~eoan_amd64.deb
(Reading database ... 220352 files and directories currently installed.)
Preparing to unpack virtualbox-6.1_6.1.10-138449~Ubuntu~eoan_amd64.deb ...
Unpacking virtualbox-6.1 (6.1.10-138449~Ubuntu~eoan) over (6.1.8-137981~Ubuntu~eoan) ...
dpkg: dependency problems prevent configuration of virtualbox-6.1:
virtualbox-6.1 depends on python (<< 2.8); however:
Package python is not installed.
virtualbox-6.1 depends on python (>= 2.7); however:
Package python is not installed.
virtualbox-6.1 depends on python:any (>= 2.6.6-7~); however:
dpkg: error processing package virtualbox-6.1 (--install):
dependency problems - leaving unconfigured
Then just install :
sudo apt-get install python-is-python2
and your problem is solved.
Simple as that.
