Qubes 4.0 Warning Qubes 4.0.1 Warning
----------------- -------------------
In new installations of Qubes 4.0, the following steps may need to be applied in dom0 and Fedora 26 TemplateVMs in order to receive updates (see [#3737]). After installing Qubes 4.0.1, please install fresh APT-based (e.g., Debian and Whonix) TemplateVMs in order to be protected from the APT update mechanism vulnerability that was patched after the release of 4.0.1.
For instructions and further details, please see [QSB #46].
Steps for dom0 updates:
1. Open the Qubes Menu by clicking on the "Q" icon in the top-left corner of the screen.
2. Select `Terminal Emulator`.
3. In the window that opens, enter this command:
sudo nano /etc/yum.repos.d/qubes-dom0.repo
4. This opens the nano text editor. Change all four instances of `http` to `https`.
5. Press `CTRL+X`, then `Y`, then `ENTER` to save changes and exit.
6. Check for updates normally.
Steps for Fedora 26 TemplateVM updates:
1. Open the Qubes Menu by clicking on the "Q" icon in the top-left corner of the screen.
2. Select `Template: fedora-26`, then `fedora-26: Terminal`.
3. In the window that opens, enter the command for your version:
[Qubes 3.2] sudo gedit /etc/yum.repos.d/qubes-r3.repo
[Qubes 4.0] sudo gedit /etc/yum.repos.d/qubes-r4.repo
4. This opens the gedit text editor in a window. Change all four instances of `http` to `https`.
5. Click the "Save" button in the top-right corner of the window.
6. Close the window.
7. Check for updates normally.
8. Shut down the TemplateVM.
