Can't install / upgrade on tails 6.3 ?

[vincib]

Description

I have a securedrop 2.6 on tails 5.14 I reinstalled a new tails key on 6.3 with the same Persistence

I tried to upgrade to 2.8 as follow :

cd Persistence/securedrop
git fetch ... checkout 2.8.0 
./securedrop-admin setup

the setup removed the old venv and failed like this:

amnesia@amnesia:~/Persistent/securedrop$ ./securedrop-admin setup
INFO: Checking apt dependencies are installed
INFO: Setting up virtualenv
ERROR: Unable to create virtualenv. Check network settings and try again.

Expected Behavior

I expected setup to install the required packages

Actual Behavior

An error appeared

Comments

I found a way to finish setup, by :

sudo apt update
sudo apt install python3-virtualenv python3-yaml python3-pip virtualenv libffi-dev libssl-dev libpython3-dev sq-keyring-linter

and then the setup and tailsconfig worked perfectly

amnesia@amnesia:~/Persistent/securedrop$ ./securedrop-admin setup
INFO: Checking apt dependencies are installed
INFO: Setting up virtualenv

Do you know if 2.8.0 is compatible with Tails 6.3 ?
