[spinoza]

Hi!

I have problem with update centos 6.8 to 7

I use how-to - https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool

Code: Select all

# cat /etc/redhat-release
CentOS release 6.8 (Final)

When I make last command

Code: Select all

#centos-upgrade-tool-cli --network 7 --instrepo=http://mirror.centos.org/centos/7/os/x86_64/ --cleanup-post

I have error:

Code: Select all

# centos-upgrade-tool-cli --network 7 --instrepo=http://mirror.centos.org/centos/7/os/x86_64/ --cleanup-post

What could be the problem?

Thanks.

There is no upgrade tool - it's been broken for about 18 months and there is no-one who cares enough to fix it. It's documented as broken in the wiki page that describes how to use it. It will KILL your system, DO NOT use it.

Ok. Thanks.

You can then tell, how I can upgrade from 6.8 to 7?

Make sure your hardware is still supported, backup, reinstall, restore.
