Hi,
According to previous tests, due to a serious bug in the
post-installation scripts, it is no longer possible to reinstall or
remove any type of package. The system is then definitely unusable.
Thanks in advance to apply following patch
To reproduce :
step 1: no hostapd on the system
ansible@srv-authenticator-100:~$ dpkg -l |grep hostapd
ansible@srv-authenticator-100:~$
step 2: install buster release
ansible@srv-authenticator-100:~$ sudo apt -t buster install hostapd
