**CAUTION:** Before proceeding, please carefully read [On Digital Signatures and Key Verification][qubes-verifying-signatures].
This website cannot guarantee that any PGP key you download from the Internet is authentic.
Always obtain a trusted key fingerprint via other channels, and always check any key you download against your trusted copy of the fingerprint.
In order to obtain a trusted fingerprint, check its value against multiple sources.
Then, check the keys you download against your trusted fingerprint.
This step is required since by (security) default TemplateVM do not have a

6. Check the name of currently used repository in `/etc/apt/sources.list` and current testing [Debian release][Debian-releases]. Update repository list accordingly
3. Check the name of currently used repository in `/etc/apt/sources.list.d/qubes-r<X>.list` and current testing [Debian release][Debian-releases]. Update repository list accordingly
```shell_session
# sed -i 's/<current stable>/<current testing>/g' /etc/apt/sources.list
# sed -i 's/<current stable>/<current testing>/g' /etc/apt/sources.list.d/qubes-r<X>.list
```
e.g. in this example we update `buster` stable repository to `bullseye` testing repository
```shell_session
# sed -i 's/buster/bullseye/g' /etc/apt/sources.list
# sed -i 's/buster/bullseye/g' /etc/apt/sources.list.d/qubes-r<X>.list
```
For installation based on Debian 10 stable, please note that the security repository of Debian testing has [recently been renamed][Debian-security-naming-convention] from `<current testing>/update` to `<current-testing>-security`. To account for that change, execute the following command.
4. Enable the QubesOS `testing` and `securitytesting` repositories
```shell_session
# sed -i 's%bullseye/updates%bullseye-security%g' /etc/apt/sources.list
```
In `/etc/apt/sources.list.d/qubes-r<X>.list`, enable the 'testing' and 'securitytesting' repository.
We do that to reduce the 'dependency hell' between Qubes repository and Kali repository.
