[Users] virtuozzo base OS and new centos 8 orientations

Mon Feb 8 18:35:45 MSK 2021

Hi,

we've published rough version of vzdeploy8 script that should eliminate problems with streams/modules mismatch that led to problems mentioned in the thread:
http://repo-backend.virtuozzo.com/vzlinux/vzdeploy/vzdeploy8

Just download & launch inside CentOS 8, no additional steps required.

The problem with *release package is that vzlinux-release is intended to replace centos*release packages. But since the VzLinux7 times, it only replaces "centos-release", not the modern variety of centos release packages.

Will add necessary Provides/Obsolete soon to fix this.

Problems with distro-sync are more interesting, should take a deeper look. In general, currently structure of Python3 packages in VzLinux slightly differes from CentOS8 so likely this is the reason.

Hi,

I created a test Centos 8 container and attempted to change the distro to vzlinux8 as per your instructions but it fails at the above step.

The output is at the bottom, any suggestions ?

The error is:
"install of vzlinux-release-3:8.2-1.vl8.x86_64 conflicts with file from package centos-linux-release-8.3-1.2011.el8.noarch"

I have attempted to remove 'centos-linux-release-8.3-1.2011.el8.noarch' but it is protected:

Error:
 Problem: The operation would result in removing the following protected packages: setup

Hi,

unfortunatly, now I have  the same pb , just did it now to check my steps , recalls from my prevoius post:

https://lists.openvz.org/pipermail/users/2021-January/008053.html

1) replace C8 repos with VzLinux => below C8 root prompt is le C8 CT that is to be moved to VZ8, VZ8 prompt is a VZ8 CT created from scratch from a "pure" vz8 EZ template where I could get VZLINUX_GPG_KEY and  RPM-GPG-KEY-Virtuozzo-8

[root at C8 /etc/yum.repos.d] # rm CentOS-*

[root at VZ8 /etc/yum.repos.d] # scp vzlinux.repo root at C8:/etc/yum.repos.d/
[root at VZ8 /etc/yum.repos.d] # scp /etc/pki/rpm-gpg/VZLINUX_GPG_KEY root at C8:/etc/pki/rpm-gpg/VZLINUX_GPG_KEY
[root at VZ8 /etc/yum.repos.d] # scp /etc/pki/rpm-gpg/RPM-GPG-KEY-Virtuozzo-8 root at C8:/etc/pki/rpm-gpg/RPM-GPG-KEY-Virtuozzo-8

2) install vzlinux-release package

# dnf install vzlinux-release

At this step I also fail on

Error: Transaction test error:
  file /etc/dnf/vars/contentdir from install of vzlinux-release-3:8.2-1.vl8.x86_64 conflicts with file from package centos-linux-repos-8-2.el8.noarch
  file /etc/issue from install of vzlinux-release-3:8.2-1.vl8.x86_64 conflicts with file from package centos-linux-release-8.3-1.2011.el8.noarch

Following new steps are not recommanded and maybe not clean at all (!?) , but I finally could proceed one step further by force remove centos-linux-release and centos-linux-repos

# rpm -e --nodeps centos-linux-release

# rpm -e --nodeps centos-linux-repos

Then also moved my epel repo files out of yum.repos.d

and now this step works

#  dnf install vzlinux-release
...

Installed:
  dnf-plugins-core-4.0.18-2.vl8.noarch     python3-dateutil-1:2.6.1-6.vl8.noarch     python3-dnf-plugins-core-4.0.18-2.vl8.noarch     vzlinux-release-3:8.2-1.vl8.x86_64     zstd-1.4.4-1.vl8.x86_64

Complete!

but now the next step  (dnf distro-sync ) fails too :-( :

# dnf distro-sync

Modular dependency problems:

 Problem 1: conflicting requests
  - nothing provides module(platform:el8) needed by module httpd:2.4:8030020201104025655:30b713e6-0.x86_64
 Problem 2: conflicting requests
  - nothing provides module(platform:el8) needed by module python36:3.6:8030020201104034153:24f1489c-0.x86_64
Error:
 Problem: package crypto-policies-scripts-20200713-1.git51d1222.el8.noarch requires crypto-policies = 20200713-1.git51d1222.el8, but none of the providers can be installed
  - crypto-policies-20200713-1.git51d1222.el8.noarch does not belong to a distupgrade repository
  - problem with installed package crypto-policies-scripts-20200713-1.git51d1222.el8.noarch
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

so I removed those conflicting packages

# dnf remove httpd python36
Removed:
  httpd-2.4.37-30.module_el8.3.0+561+97fdbbcc.x86_64                         libpath_utils-0.2.1-39.el8.x86_64                     mod_http2-1.15.7-2.module_el8.3.0+477+498bb568.x86_64
  mod_ssl-1:2.4.37-30.module_el8.3.0+561+97fdbbcc.x86_64                     python3-pip-9.0.3-18.el8.noarch                       python36-3.6.8-2.module_el8.3.0+562+e162826a.x86_64
  sscg-2.3.3-14.el8.x86_64

Complete!

but still it fails

# dnf distro-sync

It's a complete mess ... I don't know what changed from my previous success !?

advices appreciated .

thanks .
