I am writing a spec file for a new RPM package (b2) that updates package (b1), and depends on another RPM package (a).
The packages have the following scenario:
my new RPM package (b2) has directories that will be deleted during
the update
the required RPM package (a) has exactly the same directories.
When running yum update, I get the following behaviour:
resolves dependencies (ok)
transaction test (not ok)
old files from old package (b1) are still there, and there are conflicts with package a
Question:
Is it possible to solve these problems?

I came across a bug when installing certain packages using opam.
> opam install foo
Sorry, no solution found: there seems to be a problem with your request.
No solution found, exiting
According to particular form of the error message I read you are using the opam v1.2 internal solver (which you can confirm via opam config report). This solver is no longer able to cope with the repository.
Either install an external solver, see here or switch to opam v2 (currently in rc) which bundles a decent solver.
Opam was using a version of the ocaml compiler that wasn't able to install this package. So unistall the current version and use opam switch to set opam to use the latest ocaml compiler.
> opam switch x.xx.x
Then make sure to update/upgrade opam.
> opam update
> opam upgrade
I maintain the PPA for Bookworm here:
https://launchpad.net/bookworm
Recently I have changed the package name from "bookworm" to "com.github.babluboy.bookworm" based on the RDNN requirements of Elementary OS AppStore
This requires that the installation on Ubuntu is done by the command "sudo apt-get install com.github.babluboy.bookworm" instead of "sudo apt-get install bookworm".
While I have signposted this on Launchpad and the Bookworm website, there are a lots of posts and blogs on the internet from earlier asking users to use the "sudo apt-get install bookworm" command. This will install an old package (still in the PPA) which I don't update anymore.
Is there a way I can set up in Launchpad so that the older package automatically points to the new one for installation.
A hack that I can think of is to update the old package so that there is a big banner on the app providing instructions to switch to the new package. But thought of asking here if there is a more elegant way to manage package name changes in PPA
What you need is a transitional package with the old name. This will be an empty package with no actual contents, which has the new package as a dependency. When people update/install the bookworm package, it will be installed, and will pull the new package as a dependency. A future version of the new package can declare the old one as a conflict, and remove it while updating.
Debian Wiki has the information you need in much more detail. For a number of package transition scenarios, see this:
https://wiki.debian.org/PackageTransition
Case #5 : Rename is what you need from there. The exact page you want is this
https://wiki.debian.org/RenamingPackages
There are other methods explained on that page, like the 'Clean Slate Method', but the 'Transition package method' is the one which is much more cleaner, and recommended. (If you search apt for 'transitional package', you'll find a lot of them).
I just installed opam using the quick install
http://opam.ocaml.org/doc/Quick_Install.html
I now have
$opam --version
1.1.0
which is current. I ran "opam update" and "opam upgrade" to get the latest packages. However, when I install packages, it is still giving me the old versions (such as core 109.42 instead of core 109.55):
$ opam search core
Available packages for 4.01.0:
async_core 109.42.00 Monadic concurrency library
What do I need to do to get opam to give me the latest libraries?
If you previously built from source, make sure you uninstall that first. For whatever reason, even though the opam version correctly reports "1.1.0", it was still using the old repo address. After you uninstall old opam entirely, then follow the installation instructions at the link above.
You will know you succeeded when you do "opam update" and prints:
default Downloading http://opam.ocamlpro.com/urls.txt
[NOTE] The repository 'default' will be *permanently* redirected to https://opam.ocaml.org (opam-version >= "1.1.0")
I am using a server running with Ubuntu 12.04
I want to install the boost libraries in it. I know
sudo apt-get install libboost-all-dev
will make the work done, but it installs the latest version version 1.52 or above.
But I need to install the particular version 1.40 as there is a problem in a simulator which I am using for my academic purpose. What is the particular command for that so that I can install the boost libraries along with the other requirements for it like the linking files
Thanks in advance
Quick answer: sudo apt-get install libboost-dev= 1.40.0.1
If it doesn't work, continue reading.
The apt-get does support installing a particular version of a package as long as it is in an archive that apt knows about. From the apt-get manpage:
A specific version of a package can be selected for installation by following the
package name with an equals and the version of the package to select. This will
cause that version to be located and selected for install. Alternatively a specific
distribution can be selected by following the package name with a slash and the version of
the distribution or the Archive name (stable, frozen, unstable).
For e.g. if you wanted to install apache 2.20 for Ubuntu, you would do something like:
sudo apt-get install apache2=2.2.20-1ubuntu1
Note that you may need to do some dependency resolution on your own in this case, but if there are any problems apt-get will tell you what is causing them. For e.g.(on 11.04)
sudo apt-get install apache2=2.2.20-1ubuntu1 \
apache2.2-common=2.2.20-1ubuntu1 \
apache2.2-bin=2.2.20-1ubuntu1 \
apache2-mpm-worker=2.2.20-1ubuntu1
Note: You must first check if build 1.40 is still available. For that use:
aptitude search libboost
If aptitude search command don't give you sufficient results, try sudo aptitude update and then run aptitude search again.
You might have to investigate whether debs from earlier Ubuntu versions can be installed. i.e. remove the current package, download the debs and try installing them. But there could be dependency on older versions of the standard library.If so, you can probably try downloading the source from launchpad.
As a last resort, download from boost.org and build it - painfully!
EDIT: I see you have asked the same question on ubuntu forums and it seems that you have 1.48 as the default. You might have to build the library itself. Can you try this apt-get
sudo apt-get install libboost1.40-all-dev=1.40.0-4ubuntu4
If this doesn't work, you will have to build it and install it yourself. You can download the source from
Download source (1.40.0): libboost 1.40.0 source files
After it's installed, run the following command to hold your installed version, preventing the package manager from automatically updating it in the future:
sudo echo "[packagename] hold" | sudo dpkg --set-selections
Source:How to Downgrade Packages on Ubuntu
Generally you download sources, build it (some parts are not just headers like filesystem on Windows). Then you can select which subset of libraries you want to install (you can make compact version with only what you need). Then by invoking bootstrap script you build it to another directory this subset of libraries you want and then you invoke install.
Here is a pretty good description how to do it: http://ubuntuforums.org/showthread.php?t=1180792
Error while installing camlbz2
%opam install camlbz2

awk: line 1: regular expression compile failed (syntax error ^* or ^+)

I can not find anything for opam to install something like "libbz2" or whatever, any suggestions?
OPAM only deals (currently) with OCaml source packages.
Here, your problem comes from the ./configure script of the OCaml package detecting that a system package is missing, not an OCaml package (you can see that it has searched for files with a .h extension, i.e. a C include file).
To fix your problem, you need to install this system package. As Ontologiae said, the missing package is related to the libbz2 library, and include files are usually provided in development packages, so you should probably try to install libbz2-dev using the system installer of your OS. This package is not in OCaml, so there is no risk of messing up with OPAM installation.
Note that, since you use opam config -env to set your OCaml environment, even if you install OCaml packages with your system installer, there should be no bad interaction with packages installed in your homedir by OPAM.
You need to install the libbz2 C library. So, check your package system and install it.
In Debian, it's the package "libbz2-dev" (so sudo apt-get install libbz2-dev)
