In Kubuntu 15.10 (happened earlier as well), I frequently get the following error message:
Data files for some packages could not be downloaded
This is a problem regarding the update (?) of the Flash plugin. I don’t know why it occurs or how to fix it for good.
I’ve set up my Brother MFC-7820N ages ago to print and scan over the network from Kubuntu. Once in a while the router decides to change the IPs of my network devices. So just as a note to myself, here’s how to set up the scanner again:

When trying to install sun-java6-jdk on a Debian server (Lenny), I noticed that it automatically installs libnss-mdns as well as avahi-daemon. I’ve got no idea why it would do that as Avahi is the free implementation of Apple’s zeroconf which allows automatic detection of local network devices. On my Debian server it managed to interrupt DNS resolution with local hosts (using a .local address).
The following command can be used to copy dot files (i.e. configuration files starting with a dot, e.g. .bashrc) without copying all the dot directories:
find . -maxdepth 1 -name “.??*” -type f -exec cp -ia ‘{}’ /dest/path \;
For quite some time I’ve been trying to set up NFS an my MyBook World Edition (white light) to be able to mount the shared directories directly from Ubuntu.
I’ve been using Western Digital’s MyBook World Edition (white light) for the last half a year or so. Until recently, everything worked fine but last week I noticed that the disk doesn’t spin down anymore. There seems to be constant activity on the device. Using ssh to log in, I noticed that there are quite a lot of services running which I thought I had disabled previously, including twonkymediaserver and miocrawler.
