After installing Kubuntu 8.04 I faced with problem that bash completion of known hosts doesn’t work anymore. After a simple looking at content of known_hosts file I found that host name is hashing and not readable. It was done by security reason to prevent worms propagate themselves across networks.
To bring back bash completion and push system do not hashing host names just comment out the ‘HashKnownHosts’ line in /etc/ssh/ssh_config or by putting the line
Maybe it won’t be so secure but bash completion will work again.
Since a coming version of LinuxMCE will be based on Kubuntu 7.10 I started thinking about upgrade my home PC. I found this manual explained how to do an upgrade using a package manager. I played a bit with Kubuntu installed under VMware and couldn’t upgrade successful. Adopt manager crashed every time when the text of agreements should be displayed. GNOM update manager didn’t detect a new version. So, finally I have to try the manual upgrade from the command line (highly unrecommended by Ubuntu/Kubuntu developers).
Recently when I started to upgrade Kubuntu from 7.04 to 7.10 using Adopt manager I faced with problem. It doesn’t get proxy setting from the system. To solve that a following line should be added into file /etc/apt/apt.conf (you have to create it if it doesn’t exist):
User name and password can be omitted if you don’t use them.
