@FaheemMitha if you use schroot it will replace the /etc/passwd file, hence when dpkg tries to match up the users that appears in the statoverride file, it doesn't find it, hence it trows the error. If you set up schroot to not replacing the passwd file or re-installing/configuring the package the problem fixes
I am having some trouble running a script to ssh to a remote server. If I simply ssh from the command line I have no trouble reaching the server, but when I run a script to do this I get an error, "Name or service not knownname". I have added the IP address and host name to /etc/hosts and that di...
I've been working on a bash script all day and have been testing on the machine I will be using it on.
When I copy the script across from Notepad++ into a new file with nano editor inside SSH and save. It runs fine. (sh ./install).
But if I save the file (Exact same contents), upload to my web...
BTW I'd encourage anyone to setup docker if you're interested in running multiple linux variants. It cannot handle the GUI aspects but all the cli differences can be dealt with using it.
NAME
docker - System tray for KDE3/GNOME2 docklet applications
docker is a docking application (WindowMaker dock app) which acts as a
system tray for KDE3 and GNOME2. It can be used to replace the panel in
either environment, allowing you to have a system tray without running
the KDE/GNOME panel.
I can't say anything to the performance but in researching this I came across this SO Q&A titled: can you run GUI apps in a docker? that shows 3 methods for accomplishing this.
Running AppX over VNC
This method shows using the following Dockerfile:
# Firefox over VNC
#
# VERSION ...
that tells docker to start up a container (-i) means it's interactive, (-t) means I want to use image centos for the container and to run the command /bin/bash
Now, is this understanding correct? So, whatever commands I execute in the new docker, it shouldn't be visible in the processes list of my host machine?
@terdon: It's depend on distribution implementation. I only tested in GNU. POSIX defined that "The use of string arguments length, substr, index, or match produces unspecified results."
@Ramesh sandboxing (limiting impact if a application is compromised or gets out of control), cheap throw-away containers (test a command that might trash the system), run apps not meant for your own distro, deploy apps without worrying about library compatability, the list goes on
docker's an areas where we can really expand the site w/ content that's not available anywhere else too. Plus it's a boon for us to be able to field Q's on any distros more easily
we can even share images back to the registry and therefore w/ each other
Oct 10 23:24:15 bp docker[18397]: [info] Local (127.0.0.1) DNS resolver found in resolv.conf and containers can't use it. Using default external servers : [8.8.8.8 8.8.4.4]
Damn, we can't get a UNIX on this thing can we? I searched for a few and couldn't find any. I'd love to be able to test some parsing tricks on a real UNIX.
I managed to find the containers under directory /var/lib/docker/containers, but can't find the images.
Can somebody also explain the directories and files under /var/lib/docker?
Thanks
@Braiam changes are not lost, they are versioned. So here in my scenario I had the original container that was started against centos7 + I did 2 things insie that container after running it. One of which was installed vim
$ docker ps -a

I obtained a strange error message inside a chroot:
unknown user 'geoclue' in statoverride file
when running apt-get install or apt-get upgrade.
I use schroot to enter this chroot. I found that
I had a package called geoclue-2.0 installed in the chroot,
and I purged it.
apt-get purge geoclue...
@Gilles actually thats just the a user name, is not relevant to the problem per se and can change from package to package so I through that omitting it would help it to place higher in google search, since it's likely people will use "Error message: unknown user 'user' in statoverride file" and google takes single quotes (or maybe is double?) as a must have term
btw, the asterisk is a known search operator that means "fill in the blank" (which is cool!)
@Braiam but people will serch unknown user 'wibble' in statoverride file or somesuch, they won't use your title as their search. You've got it backwards.
A search operator goes into the query, not into the result.
@Gilles I'm looking if google uses the same operator for ordering results, I presume it does, as there are other posts where I've done the same and the page view went up a notch
@Braiam I have no idea what the first part of your sentence means. Regarding the last part, never replace a name by a wildcard when you quote an error message. That makes it look like the wildcard was part of the message, it's very misleading.
@FaheemMitha it makes a complete disconnection between users in the chroot and users outside, including not propagating /home. For the typical schroot use case of installing a different distribution, that's not right: what you want is to propagate human users (and their home directories), but leave system users alone. I'm planning to answer that later today.
I somewhere read that the term "to boot a computer" comes from the fact, that in the booting process, the OS "pulls itself up on its bootstraps". I have only basic knowledge about what happens while a computer boots up.
So please explain what exactly happens when a computer boots up, lets say us...
As jimmij has remarked, both your questions are pretty well-covered by Wikipedia: the etymology (which isn't on-topic here as “booting” is not specifically a Unix term), and how a typical PC boots, including the Linux case. There's a lot to be said on the topic of booting, so I'm voting to close your question as too broad. Feel free to ask more focused questions here, for example if there's something you don't understand in the Wikipedia article. — Gilles53 secs ago
I have noticed a lot of posts on AU with screenshots of their terminal showing commands and their output. This is seems like a very bad idea to me because:
You can't copy/paste the commands
They won't come up when searching
The post is heavier (in terms of the amount of data) and will take lon...
