Installation problem: App dows not start in qube, only in TemplateVM

[Markus]

I installed my notebook with Qubes-OS 4.1 two weeks ago after using Ubuntu before. My work qube is based on the Debian template. I have done some software installation in the template VM for use in the work qube and had no problems at all.
Now I want to install a software to have my data synced from my NAS to the work qube’s user folder, which is QNAP QSync: Essentials | Utilities | QNAP
The software is tested on Unbuntu, but it is possible to install it on Debian, too. I did that as I did with all the other applications and there were no error messages during the installation process with apt. However, the software now doesn’t start in the work qube. After some time I found out, that it starts in the template VM very well?!
But it should not be the goal to have personal data in a template VM.
Has anyone an idea what could be the reason for this behaviour?
Many thanks in advance for your help.

App Will Run in Debian Template, Won't Run Outside Template

I installed an application in the Debian template using sudo install apt applicationname.deb. I then shut down Debian 10 (and all other Debian templates). I rebooted Debian 10. Then I shut it down again. The application shows up in the Debian 10 template Application list. I created a new AppVM template for Debian just for this app. I found the application in the list inside the Qube settings for this AppVM and added the application. Then I ran the application. Nothing happened. The AppVM qube…

AppVM does not run TemplateVM software - i tried binding

I have installed a voip software called Zoiper 5 in a fedora-34 Template VM. It is rpm direct from website. The software works fine in the TemplateVM. I then created an AppVM based on the fedora-34-zoiper TemplateVM but the app does not run/load. I noticed the software installed a folder /home/user/.Zoiper5 to handle license keys etc. It has probably installed other software into areas that the appVM does not inherit which sucks. The app has installed files in the templateVM in the followin…

Installing Software in Qubes from .deb / .rpm

I have now found out that app files had been stored in /usr/local/bin and /usr/local/lib of the template. Copying of these subfolders to the qube has solved the problem.
Thanks very much.
