See the Release Announcement for Beta6.

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

Testing

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

Please, please any issues report to our bug tracker under the SME Server 8 section

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

Since SME Server 8.0 is still beta no contribs will be released. Once the Release Candidate status is reached contribs will be released for contrib owners to check if their packages need updating. For testing of contribs in advance of release see SME8.0 Contribs QA

Upgrade paths

Check for rpms installed from outside the standard yum repositories

After Upgrading

Reset repositories to SME 8, see below, bug 5705. This is fixed for SME Server 8.0 Beta 6

Yum

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

Note especially Bug 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
do
    db yum_repositories setprop $repo MirrorList \
    http://distro.ibiblio.org/pub/linux/distributions/smeserver/mirrorlist/$repo-8
done

Expand your yum.conf...

signal-event yum-modify

Performing the upgrade

	Note:
	You are advised to only upgrade clean machines, e.g. without contribs or other modifications.

Clean out the yum cache so upgrades work: rm -rf /var/cache/yum/*
Perform the upgrade: yum --disablerepo=smeextras --enablerepo=smeupdates-testing upgrade
Remove outdated rpm database and rebuild it (zeros not O's) rm -f /var/lib/rpm/__db.00* rpm --rebuilddb
Reset yum updates repositories to defaults, (will delete local changes) mv /home/e-smith/db/yum_repositories /home/e-smith/db/yum_repositories.pre8 /etc/e-smith/events/actions/initialize-default-databases
Perform a post-upgrade and reboot signal-event post-upgrade signal-event reboot

Potential issues that may arise

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

Check which version of smeserver-yum you are running: rpm -q smeserver-yum
If it isn't at least 1.2.0-25.el4.sme install an updated version: rpm -Uvh \ http://mirror.contribs.org/smeserver/releases/obsolete/7.1/smeos/i386/CentOS/RPMS/smeserver-yum-1.2.0-25.el4.sme.noarch.rpm \ http://mirror.contribs.org/smeserver/releases/obsolete/7.1/smeos/i386/CentOS/RPMS/yum-plugin-fastestmirror-0.2.4-3.c4.noarch.rpm

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 \
http://mirror.contribs.org/smeserver/releases/7/smeos/i386/SME/RPMS/yum-metadata-parser-1.0-8.el4.centos.i386.rpm

If you a < 7.2 system and have errors with yum upgrade try without '--disablerepo=smeextras'

yum --enablerepo=smeupdates-testing upgrade

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.

samba-3.4.3-1.1.el5.sme
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
samba3x-3.3.8-0.52.el5_5

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

rpm -e --nodeps libtalloc libtdb samba samba-client samba-common samba-winbind

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

Additional steps and potential changes

VMWare

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