Status: Final Release

SME Server Version 8.0 is the current major version of SME Server, and is based on CentOS 5.8.

See the Release Announcement for 8.0 Final.

A copy of the latest CD image can be downloaded here.


All users are encouraged to test, see our draft quality assurance testing page for tasks SME8.0 QA

All testing should be based on the released version plus updates from smeupdates-testing.

Considerations before installing

Important.png Note:
During beta testing, users were encouraged to install updates from the smeupdates-testing repository, either manually or automatically.

After installing the 8.0 final release, users should ensure that smeupdates-testing repo is disabled in the server-manager panel, if it was previously enabled during beta testing.

Important.png Note:
You are advised to only upgrade clean machines, e.g. without contribs or other modifications. If any contribs is installed you must remove them; you may re-install contribs after upgrade. All contribs settings are saved in /etc/e-smith/templates or /etc/e-smith/templates-custom so when you re-install any contrib settings will be retrieved.

Please report any issues to our bug tracker under the SME Server 8 section only if you have installed all current updates.

This way all problems can be fixed as quickly, early and efficiently as possible by the development team.

Contrib owners/maintainers should check their packages for compatibility on SME Server 8.0 final and update them if necessary.

For comments regarding contrib test results on previous SME8beta releases see SME8.0 Contribs QA

Upgrade paths

Check for rpms installed from outside the standard yum repositories and remove at least all contribs:



This is the most affordable way to get a clean and secure upgrade. During the upgrade process the existing installation is detected and the option to upgrade the existing system is displayed.

If upgrading with less than SME Server 8.0 Beta 6, reset repositories to SME 8, see below, bug bugzilla:5705. This is fixed for SME Server 8.0 Beta 6


Even if possible and tested the yum upgrade must be performed only with stable internet connections and, above all, not remotely. Loosing connection may leave your system in an unknown state.

Check for known issues, here SME8.0 QA and at open bugs for SME 8 in bugzilla.

Note especially bugzilla:5316, detach all USB drives, ie your backup

Pointing repositories to SME 8

Update the MirrorList property to point to the sme8 lists...

db yum_repositories print | grep '^sme' | cut -d= -f1 | while read repo
    db yum_repositories setprop $repo MirrorList \$repo-8

Expand your yum.conf...

/etc/e-smith/events/actions/generic_template_expand yum-modify
Performing the upgrade
Important.png Note:
You are advised to only upgrade clean machines, e.g. without contribs or other modifications.

  1. Clean out the yum cache so upgrades work:
    yum --enablerepo '*' clean all
  2. Perform the upgrade:
    yum --disablerepo '*' \
        $(echo --enablerepo\ sme{os,updates,extras,addons}) \
  3. Remove outdated rpm database and rebuild it (zeros not O's)
    rm -f /var/lib/rpm/__db.00*
    rpm --rebuilddb
  4. Reset yum updates repositories to defaults, (will delete local changes)
    mv /home/e-smith/db/yum_repositories /home/e-smith/db/yum_repositories.pre8
  5. Perform a post-upgrade and reboot
    signal-event post-upgrade
    signal-event reboot
Check for contrib packages that may need upgrading

Even though it is recommended that you only upgrade clean machines (e.g. without contribs or other modifications), it may be possible that you have a contrib installed that you forgot about. After the upgrade, use the following command to see if there are any remaining el4 packages installed that may require an upgrade from the smecontribs repository.

rpm -qa | grep el4

Note that some of the contribs packages may be listed as an el4 package but function correctly on SME8. Check the SME8.0_Contribs_QA pages for more information.

Potential issues that may arise

If you are running a 7.0 system you may need to upgrade smeserver-yum.

  1. Check which version of smeserver-yum you are running:
    rpm -q smeserver-yum
  2. If it isn't at least 1.2.0-25.el4.sme install an updated version:
    rpm -Uvh \ \

If you receive the following error while trying to upgrade:

--> Finished Dependency Resolution
Error: Missing Dependency: yum-metadata-parser is needed by package yum

Solve it by installing the correct version of yum-metadata-parser:

rpm -Uvh --oldpackage \

Upgrading samba

The Samba packages in SME Server 8.0 Beta 6 have reverted to those provided by CentOS to simplify the support needed. This version of samba provides support for Windows 7 domain logins. Due to this change from samba-3.4 to samba3x-3.3 it is necessary to remove samba if samba-3.4.x has been installed. All users of SME Server 8.0 Beta 5 are affected. Users of other versions of SME Server can check their samba version.

rpm -q samba samba3x

Here is the example output showing samba 3.4 packages installed which need removal.

package samba3x is not installed

Here is the example output showing samba3x 3.3 packages installed which need no further steps

package samba is not installed

If samba-3.4.x then you need to run two commands:

rpm -e --nodeps libtalloc libtdb samba samba-client samba-common samba-winbind
yum install tdb-tools

Now you are ready to upgrade to SME Server 8.0 Beta 6

USB drives

USB drives are detected differently on SME8, see

Additional steps and potential changes


VMware-server installations need some tweaking at this stage, see VMware_server_on_SME8.0beta5.

Problems and bugs

If you have any bug issues with upgrading please open a new SME Server 8.x file a bug here

Major Changes

  • CentOS 5 has dropped support for i586 and therefore SME Server 8 will not work on i586 hardware. See bugzilla:2845. i586 hardware means processors before and including Intel Pentium, Pentium MMX; AMD K5, K6, K6-II, K6-III and Via C3. i686 architecture processors are Intel Pentium Pro, Pentium II, Pentium III; AMD Athlon, Athlon XP and later.
