![]() ![]() This already will lead many users to reinstall Ubuntu in hopes of betterment, taking many, many hours of extra work. Package is in a very bad inconsistent state you shouldĮrrors were encountered while processing: brmfc7440nlpr:i386Īnd yes, the lead to "reinstall it before attempting." is of course utterly futile and redundant, since it just runs into the same error with another flavour.Īnd yes, adding " -force-all " just is as futile as without, obviously. LANG=en sudo dpkg -purge 'brmfc7440nlpr:i386'ĭpkg: error processing package brmfc7440nlpr:i386 (-purge): deb was sideloaded and Ubuntu does not offer a GUI way nor CLI way to solve the problem: This is because dpkg is very opinionated on those often-occurring errors, leaving many users marooned. Neither will it help in case of dpkg breakage to try any of the GUI tools like synaptic or even worse ones, since they all depend on dpkg. Obviously, You can use the remove and force flags: sudo dpkg -r -force-all 'some_bad_package'īut in very many cases that won't help at all. Such a use-case makes dpkg -r more desirable for scripted execution. So although it's true we like to ensure our scripts complete successfully and not exit in error, it might be desirable for a script to fail than complete by modifying the system outside of the target of the command. Note dpkg stops me from potentially altering the system in an unintended way if I were to use it in a scripted execution and refusing to remove both ufw and lxd: dpkg -r iptablesĭpkg: dependency problems prevent removal of iptables:ĭpkg: error processing package iptables (-remove):Įrrors were encountered while processing: Processing triggers for ureadahead (0.100.0-21).

Well, it's gone now: apt-get -y purge iptablesĠ upgraded, 0 newly installed, 4 to remove and 54 not upgraded.Īfter this operation, 23.2 MB disk space will be freed. Note when I remove iptables that lxd and ufw also removed. The consequences are that apt could automatically resolve package dependencies and remove packages other than the target supplied to the command. Where dpkg can be executed from a script without the equivalent of a " -y " switch, apt requires this to avoid user input. apt-get remove (or " purge") packageName.As always, your feedback is much appreciated.Although it's true that- sans GUI- our choices are: It’s our hope that you now have an idea about the ‘ temporary failure in name resolution‘ error and how you can go about fixing it in a few simple steps. $ sudo firewall-cmd -add-port=43/tcp -permanent To open ports 53 & 43 on the UFW firewall run the commands below: $ sudo ufw allow 53/tcpįor Redhat based systems such as CentOS, invoke the commands below: $ sudo firewall-cmd -add-port=53/tcp -permanent If the ports are blocked, open them as follows: For UFW firewall (Ubuntu / Debian and Mint) Check your firewall and confirm if port 53 (used for DNS – Domain Name Resolution ) and port 43 (used for whois lookup) are open. If the first solution did not work for you, firewall restrictions could be preventing you from successfully performing DNS queries. Then try pinging any website and the issue should be sorted out. It’s also prudent to check the status of the resolver and ensure that it is active and running as expected: $ sudo systemctl status rvice Save the changes and restart the systemd-resolved service as shown. If this file is not present or is there but you are still having the name resolution error, create one and append the Google public DNS server as shown nameserver 8.8.8.8 It contains the DNS entries that help your Linux system to resolve domain names into IP addresses. The /etc/nf file is the resolver configuration file in Linux systems. In this article, we will look at some of the causes of the ‘ temporary failure in name resolution‘ error and solutions to this issue. This can present a grave challenge as you will not be able to update, upgrade, or even install any software packages on your Linux system. This is usually a name resolution error and shows that your DNS server cannot resolve the domain names into their respective IP addresses.
