Installing software trimage in fedora template ind qubes 4.1

I am posting here because I failed to install trimage ( in a fedora template. The topic “Installing Software in Qubes (all methods)” did not help me or I did not get it.
I want to do it the right, secure and “autoupdateable” way.
It is in the repository: RPM Sphere noarch, but not in the standard repository and not in the RPM Fusion repositories (which I got working).
So I guess I have to somehow allow the RPM Sphere repositories in my template to be able to install trimage.

I hope you can help me.
Thank you very much
P.S. I know trimage is available in the debian standard repository, but to use that would be only the second best solution for me, as I want to use trimage in an existing qube that is based on fedora.

Did you try to follow these instructions from here?

Install Howto

  1. Add RPM Fusion repositories to your system
  2. Download latest rpmsphere-release rpm from
  1. Install rpmsphere-release rpm:
# rpm -Uvh rpmsphere-release*rpm
  1. Install trimage rpm package:
# dnf install trimage

Sorry, I am rather new to qubes. RPM Fusion I have added used sucessfully before.

But even if this might seem a very stupid question:
How do I go about Step 2 “Download latest rpmsphere-release rpm from
noarch/r at master · rpmsphere/noarch · GitHub” ? in my template terminal?

You can download it in any of your VM for example in disposable vm and then transfer the downloaded file to template:

Just two more questions: having used the above procedure to install trimage: will it update automatically? Are there any security issues using this method?

It seems to add its the repo here /etc/yum.repos.d/rpmsphere.repo so It should update automatically.

No idea about this repo. It seems not credible to me so I wouldn’t use it myself.
