CentOS 7.x Fix for Error: Package: uw-imap-devel-2007f-4.el7.1.x86_64 (@epel)

Just came across a new CentOS 7 only error during yum updates with EPEL yum repository and update to libc-client yum package located in EPEL yum repo. What is happening below is that 'Error: Package: uw-imap-devel-2007f-4.el7.1.x86_64 (@epel)' is complaining that it requires a specific version of libc-client = libc-client-2007f-4.el7.1.x86_64 (@epel) but yum update is trying to update libc-client to a newer version libc-client-2007f-14.el7.x86_64 (epel).

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.

Update 2: July 30th, 2017 - workaround fix applied to latest Centmin Mod 123.09beta01 branch using centminmod.com mirrored copy of missing uw-imap-devel and libc-client 2007f-4 version of RPM packages for CentOS 7 only issue Beta Branch - CentOS 7 workaround fix for EPEL uw-imap-devel & libc-client issues

Update: July 30th, 2017 - for now I have updated Centmin Mod 123.08stable and 123.09beta01 with new PHPIMAP variable set to PHPIMAP='n' by default (Beta Branch - add PHPIMAP option to disable or enable PHP Imap extension), so when PHP compiles/installs are done IMAP php extension is disable temporarily until I can figure this out

Code (Text):

yum -y update --disableplugin=priorities

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Normally, there should be an accompanying updated uw-imap-devel version i.e. uw-imap-devel-2007f-14.el7.1.x86_64 to match libc-client-2007f-14.el7.x86_64 (epel). But EPEL yum repo doesn't have it. I see Fedora Rawhide does uw-imap-devel-2007f-14.fc27.x86_64.rpm Fedora Rawhide Download. So technically, if you want you can grab the Fedora Rawhide SRC RPM and rebuild a custom RPM for CentOS 7 but then you'd be responsible for updates to uw-imap-devel, libc-client RPMs everytime.

Fixing Issue

There are many ways to fix this, but easiest for now is to lock libc-client updates to the one uw-imap-devel wants to use, libc-client = libc-client-2007f-4.el7.1.x86_64 (@epel).

---

You can use yum versionlock plugin to lock a yum package to a specific version so yum updates won't update it and ignore newer versions of the package - libc-client in this case.

SSH commands are as follows

Code (Text):

yum -y install yum-plugin-versionlock
yum versionlock libc-client

listing versionlocked packages using command

Code (Text):

yum versionlock list

will give

Code (Text):

yum versionlock list
Loaded plugins: fastestmirror, priorities, versionlock
0:libc-client-2007f-4.el7.1.*
versionlock list done

Now yum updates will skip over libc-client even if there are updates.

 

I will add this to 123.09beta01 too for automatic detection soon, but for now you can manually do it.

edit: 123.09beta01 has been updated so centmin.sh menu option 23 submenu option 2 to update /usr/local/src/centminmod code. Then exit centmin.sh and re-enter /usr/local/src/centminmod directory and run centmin.sh and exit again via centmin.sh menu option 24. This process will trigger auto fixing and auto run of above manual steps if yum-plugin-versionlock doesn't exist.

 

Yeah you can also setup a cronjob to auto update centmin mod code so whenever you run centmin.sh it will be with latest code always Beta Branch - Cronjob Auto Updating Centmin Mod Code Guide

 

hmm seems this bug still breaks fresh 123.09beta01 install's initial PHP install - working on the solution now

looks like on fresh initial installs, libc-client that gets installs is the newer incompatible one

Code (Text):

---> Package libc-client.x86_64 0:2007f-14.el7 will be installed

hmm making it trickier is it seems EPEL repo removed older working libc-client 2007f-4.el7 from availability on fresh installs now so can't downgrade to it from 2007-f14.el7 !

edit: looks like EPEL is now starting to show for non-devel uw-imap newer 2007f-14 version uw-imap-2007f-14.el7.x86_64.rpm CentOS 7 Download so could be temporary issue in delays for populating EPEL yum mirrors with the devel version of uw-imap-devel-2007f-14.el7.

edit: even more messed up is my local virtualbox test server's EPEL repo is reporting uw-imap-devel as not available at all on fresh centmin mod 123.09beta01 installs rather than older 2007f-4 version.

even trying all repos, don't show uw-imap-devel 2007f-4 or any version as available

So looks like I need to create a mirror for uw-imap-devel-2007-f-4 RPM for CentOS 7 and libc-client-2007f-4 RM for CentOS 7 as EPEL yum mirror doesn't problem them now! Could be problem with EPEL yum mirrors themselves or a change on developer end as to what is built ? I've made local mirror for these RPMs on official centminmod.com site at https://centminmod.com/centminmodparts/uw-imap/ so will see about working that into Centmin Mod 123.09beta01 branch.

So manual fix would be like but will also version lock uw-imap-devel + libc-client

For now I have updated Centmin Mod 123.08stable and 123.09beta01 with new PHPIMAP variable set to PHPIMAP='n' by default (Beta Branch - add PHPIMAP option to disable or enable PHP Imap extension), so when PHP compiles/installs are done IMAP php extension is disable temporarily until I can figure this out

Summary

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
