SVN in chroot says you don’t exist

Wednesday, September 29th, 2010

You may one day set up a chroot environment and find you get this message when you try to ssh or use svn (using ssh):

You don’t exist, go away!
svn: Connection closed unexpectedly

In addition to my assurance that you do indeed exist in the universe, let me tell you how I fixed it.

Check your chroot /etc to make sure passwd and shadow exist for your user and the IDs are correct.

Then, note that when svn does a repository connection it uses which can require proper DNS resolution. In my case, I had to add the repository domain name into the chroot /etc/hosts file.

Then I existed in more ways than one.

Fedora13 kernel update breaks video

Friday, September 10th, 2010

I did my usual old “yum update” the other day and it hosed up my video upon reboot!

Never fear, it is a known problem, and has probably already been fixed by the time you read this.

But one thing I learned is that you should have akmod installed so the system will be smart and use a previous video driver if it fails. To do this, all I needed to do was:

yum install akmod-nvidia

then, on reboot, it was all working again.


One thing to note is that when you do a yum update, make sure if there is a new kernel that there is a corresponding nvidia update for it! If not, then DO NOT yum update, and try again in a day or so. Eventually there will be a matching nvidia update and you are safe to update. Example:


kernel x86_64 updates 22 M

kernel-devel x86_64 updates 6.4 M


kernel x86_64 @updates 102 M

kernel-devel x86_64 @updates 23 M

Installing for dependencies:

kmod-nvidia- x86_64 1:260.19.36-1.fc13.3 rpmfusion-nonfree-updates 2.8 M

Removing for dependencies:
