Basic summary of issues outlined in CentOS 7.x - Fix for Error: Package: uw-imap-devel-2007f-4.el7.1.x86_64 (@epel)

Issue only relates to CentOS 7 systems and EPEL yum repo usage

1. For existing Centmin Mod installs with CentOS 7, EPEL yum repo just released a new libc-client-2007f-14 rpm package to update libc-client-2007f-4 version. But uw-imap-devel 2007f-4 package which is required for PHP-FPM imap php extension depends on libc-client-2007f-4 older version. Usually, if libc-client-2007f-14 was released, an accompanying uw-imap-devel 2007f-14 version would be updated too. But CentOS 7, EPEL 7 yum repo does not have a uw-imap-devel 2007f-14 update. So yum updates report a conflict as yum update wants to update libc-client-2007f-4 to libc-client-2007f-14 but uw-imap-devel 2007f-4 complains as it depends on older version.
2. For fresh Centmin Mod installs with CentOS 7, initial installation will install libc-client from EPEL which is is the newer conflicting version = libc-client-2007f-14. But EPEL yum repo also removed libc-client-2007f-4 older version so you can't downgrade from libc-client-2007f-14 to libc-client-2007f-4 as libc-client-2007f-4 doesn't exist anymore. To add to the issues, EPEL yum repo for CentOS 7 is now missing the uw-imap-devel package altogether so 2007f-4 or 2007f-14 versions of the package are not available via EPEL yum repo !
3. Update August 3, 2017: newer issue is 2007f-16 version of libc-client and uw-imap-devel were released by EPEL which is proper way to release these with matching 2007f-16 versions for dependencies. So Centmin Mod 123.08stable and 123.09beta01 have been updated to versionlock and update to 2007f-16 versions of these 2 packages.

So this 123.09beta01 update, fixes these 2 issues by making 2007f-4 version of uw-imap-devel and libc-client EPEL 7 RPM packages available via a centminmod.com local hosted mirror which is now installed on fresh 123.09beta01 installs and using yum versionlock plugin are locked to 2007f-4 versions until we can dig deeper into sorting out EPEL 7 mess. For existing 123.09beta01 installs, if you update via centmin.sh menu option 23 submenu option 2 and exit centmin.sh and re-run centmin.sh then the same workaround fix will automatically be done in background for your system.

Confirmed working for fresh 123.09beta01 installs checking post install check list to see if PHP-FPM was installed

what do you both get when you run

Code (Text):

cd /usr/local/src/centminmod
git stash
git pull

seems EPEL released a new uw-imap-devel-2007f-16 from uw-imap-devel-2007f-4 which requires even new libc-client-2007f-16 instead of 2007f-14 or 2007f-4.

@ArisC on fresh install need install log

You'll need to post on the forums with the following info

• Server or VPS details ? XEN, KVM, OpenVZ, VMWare or dedicated server ? OS ? CentOS 6.7 or 7.2 ? 32bit or 64bit ?
• What version of Centmin Mod ? .07 stable or 08 stable or .09 beta01 or another branch version ?
• Was it fresh install or upgrade ?
• Method of install ? Via centmin.sh menu option 1, Git install or curl one liner install as outlined at centminmod.com/download.html ?
  
• How long ago did you install Centmin Mod ?
• There's numerous code changes, bug fixes over time, so ensure you have latest Centmin Mod code installed by upgrading your Centmin Mod code as instructed below.

Troubleshooting Initial Install

To troubleshoot initial installation, you need to check the initial install log at /root/centminlogs and instructions under Sharing logs and errors heading for using Pastebin.com or Gists to share a sanitised version of the contents of the initial install log. You can see full details at How to troubleshoot Centmin Mod initial install issues

Example list /root/centminlogs files in date ascending order and grep for install.log

Code (Text):

ls -lahrt /root/centminlogs | grep install.log

example output returns install log at /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

Code (Text):

ls -lahrt /root/centminlogs | grep install.log
-rw-r--r--  1 root root 2.2M Oct 11 01:40 centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

in SSH use cat to ouput contents of /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log. Clear your SSH client window/buffer so only output is the contents of the file

Code (Text):

cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

Then copy and paste into Pastebin.com or Gists entry. If your SSH window scroll buffer isn't that large to get the whole contents of the install log, you can download file manually and copy and paste contents. But makes sure it's sanitised version of the contents of the initial install log as outlined at How to troubleshoot Centmin Mod initial install issues

 

Should be fixed in latest updated 123.09beta01 as libc-client and uw-imap-devel has a newer 2007f-16 version that properly matches now so unlocking 2007f-4 to allow 2007f-16 update. But I am locking libc-client and uw-imap-devel to new 2007-f16 after update for more stability right now as who knows what EPEL folks will do regarding these packages down the road.

Fixed CentOS 7 systems should have version locked 2007f-16 based libc-client and uw-imap-devel EPEL yum packages listed from command

Code (Text):

yum versionlock list

Code (Text):

yum versionlock list
Loaded plugins: fastestmirror, priorities, versionlock
0:libc-client-2007f-16.el7.*
0:uw-imap-devel-2007f-16.el7.*
versionlock list done

Change log for uw-imap-devel 2007f-16 at uw-imap-2007f-16.el7.x86_64.rpm CentOS 7 Download so July 31 fix was for broken/missing uw-imap-devel package from EPEL7 YUM repo when they released libc-client 2007f-14 update without a corresponding uw-imap-devel 2007f-14 update.

 

It probably is fixed as 2007f-16 matching versions of both uw-imap-devel and libc-client YUM packages are available in EPEL7 now. Just I chose to lock their versions for stability right now. Don't need for a repeat of this bug when they release future versions with missing dependencies.

In future if you want to check if there's matching updates you can do yum update with --disableplugin=versionlock flag

List updates

Code (Text):

yum list updates libc-client uw-imap-devel --disableplugin=versionlock

Check updates

Code (Text):

yum update libc-client uw-imap-devel --disableplugin=versionlock

If there are updates, can re-engage an updated version lock

Code (Text):

yum versionlock delete libc-client uw-imap-devel
yum versionlock libc-client uw-imap-devel

Show installed versions

Code (Text):

yum list installed libc-client uw-imap-devel
