You've reached the website for Arch Linux, a lightweight and flexible Linux® distribution that tries to Keep It Simple.
Currently we have official packages optimized for the x86-64 architecture. We complement our official package sets with a community-operated package repository that grows in size and quality each and every day.
Our strong community is diverse and helpful, and we pride ourselves on the range of skillsets and uses for Arch that stem from it. Please check out our forums and mailing lists to get your feet wet. Also glance through our wiki if you want to learn more about Arch.
Due to the SONAME of /usr/lib/libmozjs-52.so not matching its file name, ldconfig created an untracked file /usr/lib/libmozjs-52.so.0. This is now fixed and both files are present in the package.
To pass the upgrade, remove /usr/lib/libmozjs-52.so.0 prior to upgrading.
The new version of glibc removes support for NIS and NIS+. The default
/etc/nsswitch.conf file provided by filesystem package already
reflects this change. Please make sure to merge pacnew file if it exists
prior to upgrade.
NIS functionality can still be enabled by installing libnss_nis
package. There is no replacement for NIS+ in the official repositories.
pam 1.3.0-2 no longer ships pam_unix2 module and pam_unix_*.so
compatibility symlinks. Before upgrading, review PAM configuration files
in the /etc/pam.d directory and replace removed modules with
pam_unix.so. Users of pam_unix2 should also reset their passwords
after ...
The zita-resampler 1.6.0-1 package was missing a library symlink that has been readded in 1.6.0-2. If you installed 1.6.0-1, ldconfig would have created this symlink at install time, and it will conflict with the one included in 1.6.0-2. In that case, remove /usr/lib/libzita-resampler.so.1 manually before updating.
Following 9 months of deprecation period, support for the i686 architecture effectively ends today. By the end of November, i686 packages will be removed from our mirrors and later from the packages archive. The [multilib] repository is not affected.
For users unable to upgrade their hardware to x86_64, an alternative is a community maintained fork named Arch Linux 32. See their website for details on migrating existing installations.
The perl package now uses a versioned path for compiled modules. This means that modules built for a non-matching perl version will not be loaded any more and must be rebuilt.
A pacman hook warns about affected modules during the upgrade by showing output like this:
WARNING: '/usr/lib/perl5/vendor_perl' contains data from at least 143 packages which will NOT be used by the installed perl interpreter.
-> Run the following command to get a list of affected packages: pacman -Qqo '/usr/lib/perl5/vendor_perl'
You must rebuild all affected packages against the new perl package before you can ...
