Hi all, I have experienced ollowing problem during my Fedora 23 update.

I have chosen Restart & Update in the shutdown menu. After system restart the notification bar displayed a message about update failure, with following error message (during Oracle Virtualbox update):

We’re sorry: the update failed to install. Please wait for another update and try again. If the problem persists, contact your software provider.

Detailed errors from the package manager follow:

Curl error (6): Couldn't resolve host name for https://www.virtualbox.org/download/oracle_vbox.asc [Could not resolve host: www.virtualbox.org]

I have tried to add Oracle GPG key following this guide:

wget -q https://www.virtualbox.org/download/oracle_vbox.asc

and

sudo rpm --import oracle_vbox.asc

Any help is appriciated.

Update:

nslookup result:

[shimon@localhost ~]$ nslookup www.virtualbox.org
Server:     213.46.172.37
Address:    213.46.172.37#53

Non-authoritative answer:
Name:   www.virtualbox.org
Address: 137.254.60.32

The error message you're reporting says that it's unable to turn the machine name www.virtualbox.org into an IP address so that it can connect to it and download the file. Please edit your question to include the results of this command:

nslookup www.virtualbox.org

so that we can find out if you're having DNS issues. My computer can resolve the address and connect (although it doesn't respond to pings) so the issue's probably at your end.

And while I'm thinking about it, if you know what your DNS servers are, please include their IP addresses in your edit.

Thanks for your reply. I have updated my post with nslookup result.

So, your machine can resolve www.virtualbox.org into the correct IP (137.254.60.32). Maybe the problem was something intermittent with your provider or on Oracle's system. Have you tried wget https://www.virtualbox.org/download/oracle_vbox.asc or wget http://www.virtualbox.org/download/oracle_vbox.asc in the meantime?

I have tried wget with both http/https, and both work OK. Could it be that somehow the name cannot be resolved to IP during update process (computer restart)? Can be VirtualBox update triggered alone, so that it doesn't block rest of updates?

If that's true, whatever was causing the DNS issue has probably cleared up. Try the update again and see how it works.

@shimon001: You mean, you want to perform a dnf upgrade even though the connection to one specific repo (ie virtualbox) fails? In that case you have to temporarily disable that repo. (dnf --disablerepo virtualbox upgrade). There is no --skip-broken option known from yum.

I have ran the update again as root from command line using dnf update, according to the log everything updated successfully (even Virtualbox). Maybe Virtualbox cannot be updated during system restart (maybe the network connection is down and the .asc file cannot be downloaded.
