I wanted to update my SSL certs on my Pi 3B+ which is running NextcloudPi. I did not touch the Raspbian System on it for at least 2 months. I am the only one who is able to login.
I connect via SSH using XFCE Terminal on Manjaro:
Login works perfectly, but if then I try to use
sudo su sudo apt-get update
and many more I get
Segmentation fault as error.
sudo vi /etc/...default.conf do actually work.
Like already mentioned, I did not even access the Pi for 2 months or longer, and before everything worked just fine.
It is running NextcloudPi on v1.6.8.
