Centos 7 Template Cannot be Installed on Qubes OS 4.1.0-rc4

[xihoto2844]

The following attempt to install CentOS-7 template via dom0 terminal / command: sudo qubes-dom0-update --enablerepo=qubes-templates-community qubes-centos-7

results with the following error message: qvm-template: error: Same version of template ‘Centos 7’ not found

OS Details:
xen_version: 4.14.2
Linux 5.10.76.1.fc32.qubes.x86_64

The same command works in Qubes 4.0, this could be a bug?

Centos 7 isn’t available for v4.1

unlike 4.04

Not a bug.
You can install Centos 8 from qubes-templates-community-testing - it
hasn’t yet migrated to the standard repository.
Centos 7 isn’t built for 4.1

I never presume to speak for the Qubes team.
When I comment in the Forum or in the mailing lists I speak for myself.

You may also wish to enable testing repositories and then use qvm-template-gui to check which templates are available for Qubes 4.1.

You may also wanted to keep in mind that Centos 8 is deprecated and updating is not possible, so we are waiting for Centos8 Stream template

Good to know, thank you all!

Bumping just in case someone gets to find this old thread via suggestions - as it happened to me.

While CentOS 7 may not be that easily available in 4.1, one can still download the RPM manually, copy it to dom0 and install locally. It may not be supported but I found out it works fine - along with updating the system to the newest version.

Simply:

qvm-run --pass-io qube 'cat /home/user/Downloads/qubes-template-centos-7-4.0.1-201909141946.noarch.rpm' > qubes-template-centos-7-4.0.1-201909141946.noarch.rpm
sudo dnf localinstall ./qubes-template-centos-7-4.0.1-201909141946.noarch.rpm

one can, with some clever tricks, update it to CentOS 8.5 and then migrate to a successor (AlmaLinux, EuroLinux, Rocky Linux, CentOS Stream). I wrote appropriate information on that in the Community Docs

Thanks!

@aronowski

I already did it here

Easy way to provide Qubes with multiple Linux distro templates within minutes?

Inspired by Exotic OSes which I tried on Qubes topic and intrigued by Bedrock Linux long time before even heard of Qubes, I’m trying to see if it’d be possible to get multiple Linux distro templates in Qubes by simply hijacking single one default template from Qubes. So far I created StandaloneVM based on debian-11-minimal and hijacked it successfully with Bedrock Linux and then installed following strata (most analog would probably be Qubes templates inside dom0): user@debian-11-min-bedrock:…

That makes me wonder if the current state of AlmaLinux’ ELevate project would allow to upgrade a 8.x qube to AlmaLinux 9.0.

They recently announced an initial, non-production-ready support for 8 to 9 migration but I’m curious if this would work within a qube rather than non-qube system. Has anyone tried it?

Or if that’s not possible, I’ll just wait for 9.0 ready-made templates.

Try and tell

[aronowski]

Nope, either I’m doing something wrong or it’s normal that it (leapp) throws a Python exception upon launching.

The good thing about the whole situation is that I noticed the earlier instructions on migration were wrong since I had already tweaked a system before writing them. This time with the new PR I started from a fresh CentOS 8.2 install.
