Titel: /etc/resolv.conf gets creamed by latest upgrade?

I just did an aptitude upgrade and I lost my internet because my DNS access failed. I found that my /etc/resolv.conf had been turned into a link pointing to an empty file /etc/ppp/resolv.conf.

I put back a valid /etc/resolv.conf and all came good again.

running from the fish menu or console

"netcardconfig"

also resets the conections

other reports in #kanotix suggest the just by rebooting the connections are reactivated ( bit drastic )

that being said,, good post in tracking pinpointing the culprit

BTW please DO NOT use adept, aptitude, kpackage, synaptic to do an upgrade or dist-upgrade.. you will get caught out and bork yourself, and due to kanotix being debian sid dist-upgrade is the recommended cmd to keep your system current, as a straight upgrade is somewhat depreciated for sid due to "upgrade" often has problems to understand when dependeny libraries change their names, which happens quite often in sid.

A dist-upgrade does a more clever job as it understands the "sid" flow.. and recogisises that it is not a static repositry (unlike some debian forks that's why upgrade is usually not problem there)

The only way to dist-upgrade is as follows

Ctrl+Alt+F1 ; logon as root, type init 3 ; apt-get update ; apt-get dist-upgrade ;run fix-fonts ; run update-scripts-kanotix.sh ; run fglrx or nvidia script if xorg updated [DO NOT DIST-UPGRADE [or UPGRADE] with adept or synaptic] *always* check Current Warnings on http://kanotix.com/News.html

I got caught by resolv.conf breakage too... added the nameservers by hand and all is well.

Your observation about using apt-get vs aptitude is interesting... I just started using aptitude, now I will return to using apt-get.

Rebooting didn't fix anything for me. That's when I looked and found the /etc/resolv.conf problem. I'm using a static IP address but I guess if you are using DHCP then a reboot would probably fix the problem.

I've been using aptitude since I started with kanotix a couple of years ago and never had a problem (well, other than the sid mess with over xorg, kde, etc which affected us all). Aptitude is just a better apt-get (and it's intended replacement from a user perspective from my understanding).

If you do a dist-upgrade, and you lose your connection, this is all you need to run:

/etc/init.d/networking restart

it will restart networking, and everything should be fine, this also happened to me, but that's all that is required to fix it. My script will also run this automatically if it detects a broken connection when it starts, but it can't help if the connection drops while the script is runninig, after dist-upgrade. But running it again should bring that up after a brief wait.

Easy way to see if your connection dropped is after dist-upgrade finishes, and the fixes are applied etc, simply try to connect to kanotix.com with lynx, like this: lynx kanotix.com

If the connection failed, this probably happened to you, and running the networking restart is all that you need to do.

Seriously, aptitude is a nice tool and very well designed suited for stabilized distributions (Debian Stable, Ubuntu, Mepis, ...). But it is not designed for Debian Sid - and that's what Kanotix is all about. And don't believe the marketing speak, there is no "better apt-get".
