I inadvertently upgrade to Ubuntu 10.10 developmental while trying to upgrade to Ubuntu 10.04.1. Can anyone can in downgrading back to a stable release without having to reformat everything?

I currently run 9.10 and have / and /home mounted on different partitions. From what I understand, I can do a fresh install of 10.04 on / while preserving my settings on /home. What about the development tools? I currently have Apache web server, Tomcat, MySQL, PostgreSQL installed. I presume I will have to reinstall them if I do a fresh install right? So if I want to preserve these dev tools as they are I should only do an upgrade from the update manager? Are there any major advantages to a clean install over an upgrade?

It was during one of the questions about installing an updated config file. If I run "sudo apt-get dist-upgrade", it complains that it can't lock the directory /var/lib/dpkg. What can I do to recover this and continue with the upgrade?

I'm looking to upgrade the infrastructure in our office (small web development shop). I'm going to buy a small floor standing rack and in it we will have a dedicated firewall / VPN box, a web development server and a fileserver (for now). I intend to use Debian squeeze for everything.
My main question is what should I do about RAID? I've not used it myself before, instead relying on backups to removable disks. This time I want to do everything properly, and a measure of disk redundancy is required so I guess we will be going for RAID 1.
I'm looking at this [URL].. server which comes with an Intel ICH10R RAID controller on board, and also has an option to add a 3ware 9650SE-LP. The site says the Intel chipset is Windows only, so I guess the 3ware alternative is the way to go. The server also has two 3.5" hot swap drive bays. Could anybody advise me if the 3ware card is a good choice for use with Debian? Also, how can I monitor the health of the drives with standard Debian tools out of the repos? Any other RAID tips are also interesting for me.

Apparently the hole can be exploited simply by sending a specially crafted certificate to the client, causing deallocated memory to be accessed in the ssl3_get_key_exchange function (in ssls3_clnt.c). While this usually only causes an application to crash, it can potentially also be exploited to execute injected code.

I am new to git (and storing multiple copies of my code).
I was using git for one month (git status, git add, git commit) to store my files.
I have problems to add more files to my branch
git add BasisExpansion.R
fatal: Unable to write new index file
this was working great unless the day my system administrator destroyed my main partition (it was an accident) and installed everything from scratch. My home directory stayed intact (I did not lose any files not git files that are stored under /home). But from this point of time git returns always that error. My system administrator creater the same user and group as my old user was but this didnot fix the problem.
I am not sure If I can recover my old git structure or would it be better to wipe out the old git dir and start a new one?

View 4 Replies View RelatedII'm a front-end web developer, I've always developed on Windows with technologies like XHTML, CSS, Javascript and Flash, I've dabbled with PHP and MySQL. I am well used to Windows workflows and tools, from Photoshop to Notepad++, Filezilla and WAMP server stacks to After Effects, and a swathe more - but always on Windows.I'm at a point where I think I need to start seriously developing on a Linux box, specifically at the moment to create web apps based on Node.js, but compiling tools and programs has become a task I'm more frequently required to do.
My question? I need to get my hands on a user-friendly install of Linux, but which one? I need common interface developer tools (lists welcome) to replace... well as many tools I have on Windows as possible.I need to be readily connected to the internet, I need OS updates to not destroy my workflow by crashing the OS, as I've seen Ubuntu do to various friends. I want efficiency, I need to be able to customise what I need to in order to perform development tasks.I guess this could be a long list, but - I don't have practical working knowledge of the Linux OS, nor how it "compares" to Windows (excuse my faux pas). I'm obviously willing to learn, but I'm far, far more keen to just... continue interface development, just on Linux instead of Windows.
I have an old Pentium-4, 2GB RAM, 2X160GB IDE-Hard disk computer. I am learning software development and I need a distribution with support for
(a) Oracle/Sun Glassfish v3 server
(b) Apache web server
(c) MySQL server
(d) Postgres server
(e) Sun virtual-box (headless)
(f) Webmin
For my home use, I need a proxy server and a file-and-print server (e.g. samba) I need to be able to run it headless. It should be easy to configure, but should also be like a real-world linux-distribution.
I am working with TS7260 and ARM9 board with Debian os I want to interface any database so will you guide what header files are required and how to compile it..

Lucky thing is All the drives (C:, D:, E:) are currently mounted and I'm in UBUNTU. I guess its possible to re-create the partition table using current status. how to do this. This is a lab computer. If its not recoverable. I'm completely screwed!
When doing an install of Linux Mint, I accidentally installed on a partition that already had data on it, so now that partition has a clean install of Mint instead of the data that was there before.I was hoping that I could at least recover some of the data from this partition, so my questions would be what, if anything, could I recover, and how would I go about doing that?

Is it possible to have both Windows XP and Linux web server in one computer?
I wanted to design a project in linux which could contain programming languages(C, perl, PHP, HTML, XML etc) basically a web based project. Why I have chosen to build on Linux is because it is Open Source, and lot many things can be automated through scripting languages, which in windows I don't know. So, I have installed linux on a virtual machine(Host-Windows 2007 & Guest Linux CentOS), CentOS(command line interface). Since I am a beginner, so I want to know what all tools can be used to facilitate and ease my development process. Some which I know are listed below:
1) Using Putty so that can access the Linux machine from anywhere within the network.
2) Since I want to develop on Linux, but want to use windows as developing platform. So have downloaded Eclipse Editor (C/PHP) on windows. But want to know how can I access linux files from here?
3) Installed Samba, and still trying to figure out how can I access linux files remotely on Windows.
4) How can I ease my development process and what all tools I can use..??
I'm looking for some advice on choosing the proper distribution for building a hardware/software development environment.
My main field of interest would be:
- HDL (VHDL mainly)
- FPGA/CPLD (synthesis, simulation etc)
- CSystemC
- Tcl scripting
- network hardware applications development (FPGA-based network processors i.e.)
Key (or nice to have at least) system features would be:
- large, stable and willing to help community (especially the large developer part of which would be welcomed)
- support for wide spectrum of development tools (proprietary and open source)
- bunch of docs, tutorials, guides, hints for devel's
As far as my online research went, I've manage to shorten it down to 3 favorites:
- Debian
- Fedora/CentOS
- Gentoo
I'm running Mac OS X 10.5.8.

If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folderIf I end up needing to reinstall everything in this folder, what is the best way to go about doing this?
