The following advisory was just received from cPanel team: Dear cPanel Partner, The CPAN module IO::Compress::Zlib version 2.006 has caused several issues for some. The problems arise due to a dependency upon IO::Compress::Base not being correctly installed. This is due to some mirrors not being updated with the proper dependency information. Since the dependencies are incorrect, the module no longer functions properly. The most noticeable problem from this is the complete breakage of DNSAdmin, however other issues are caused. To alleviate the problems, cPanel is providing a hotfix which can be applied in the following manner: From the command line: 1. SSH into your server as root. 2. At the command line, execute the following: /scripts/autorepair io_compress_gzip Or from WHM: 1. Log into WHM as root 2. Enter the following URL into your browser's address bar: https://__YOURSERVERHERE__:2087/autofixer (example: https://www.example.com:2087/autofixer) 3. When prompted, enter: io_compress_gzip The autofixer will report it is applying "IO::Compress::Zlib autorepair verison 1.1" This process replaces the IO::Compress::Zlib with version 2.005. Also a hold back has been enabled to prevent the perl installer process from installing IO::Compress::Zlib version 2.006 until a new version is available that fixes this problem. For non-cPanel servers that experience this issue, it is also possible to resolve this manually by performing the following steps: 1. SSH into your server as root. 2. Execute the following commands: wget http://search.cpan.org/CPAN/authors/id/P/PM/PMQS/IO-Compress-Base-2.006.tar.gz tar xfzv IO-Compress-Base-2.006.tar.gz cd IO-Compress-Base-2.006 perl Makefile.PL make make install The manual fix will also work for a cPanel server. In order to expedite the process, we have also updated all published builds to include the fix.
