Failed Qubes Updates for Template

I keep getting fail to refresh and fail to fetch and reading from proxy failed errors when i try to update my debian 12 template using the Qubes OS Update GUI. It has some additional packages like browsers and messaging apps.

Normally i open the template terminal from dom0 and update it and that usually fixes it but i have been trying the last few days with no success. terminal says that all the packages are up to date. But the qubes os update gui tells me otherwise

any ideas?

Check the network connection in your “Default update proxy” qube that isset in Qubes Global Settings. It’s used for template updates.

Do you mean qubes-dom0-update command?
It only updates dom0, not templates.

Yup its set to the correct ones. The other templates are updating fine.

in dom0 i would run qvm-run -u root [name of template] xterm.

then sudo apt-get upgrade

So if you run sudo apt update && sudo apt upgrade in the problematic debian 12 template terminal then it’ll refresh the repo information successfully and tells you that there are no new updates available?

im getting fail to fetch [url of package] invalid response from proxy HTTP/1.0 500 Unable to connect server: tinyproxy/1.10.0 content-type: text/html Connection close [IP: 127.0.0.1 8082]

What’s your template update qube? sys-whonix?
Are you sure that you don’t have the same error in other non-whonix templates?

my default update proxy is set to sys-firewall which is set behind a sys-vpn

sys-firewall->sys-vpn->sys-firewall-vpn->sys-net

Im sure the others are working. I just updated them

Whonix update proxy set to sys-whonix ofc.

Edit: the packages that are failing are signal and element

Are you able to access the repository links from the qube connected to sys-vpn?
Maybe they are blocked by your VPN?

woah! you are right… My VPNs DNS settings must have added both repos to a block list. added them to whitelist.

Thanks!
