Today I decided to Upgrade my Raspberry Pi 3B from Raspbian to Ubuntu MATE, and I am really enjoying it. However, when I tried to install the Ubuntu Software Center and entered my password, the Boutique gave me an error:
Failed to download package files Check your Internet connection. Details >
I tested my wifi is working perfectly: I have a good connection on my phone and on my laptop. Also, I can open Firefox and browse the internet normally on my PI. As if nothing had happened.
If I click on Details, then this is what I get:
Failed to fetch http://ports.ubuntu.com/pool/main/p/python-cryptography/python-cryptography_1.2.3-1ubuntu0.1_armhf.deb 404 Not Found [IP: 126.96.36.199 80] Failed to fetch http://ports.ubuntu.com/pool/universe/a/apt-xapian-index/apt-xapian-index_0.47ubuntu8.3_all.deb 404 Not Found [IP: 188.8.131.52 80] Failed to fetch http://ports.ubuntu.com/pool/main/p/python-cryptography/python3-cryptography_1.2.3-1ubuntu0.1_armhf.deb 404 Not Found [IP: 184.108.40.206 80]
Can someone please tell me how I can fix this?
P.S. The ip adress in the details is Canonical’s server in Scotland. I live in London, England.
