Hi all!
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: 91.189.88.150 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.
could it be a network hiccup ? I can ping ports.ubuntu.com (same ip address).

In case of a network hiccup, then the internet in general and on all devices would have crashed. But it does work, just not the Software Boutique for some reason.
I tried rebooting my Pi, I tried disconnecting and reconnecting to my Wifi network, and I tried rebooting my router. Do you know how to fix this? If I try installing the recommended alternative, ‘Software’, then I get this error message:

What am I doing wrong?
P.S. I have found out that this is literally the same with any other app. Only the Alarm Clock app works out of all the others I tried. How can I get the Software Boutique to work properly? I cannot even use snap to get around this…
Edit = Not only the alarm clock, but geany works to. That is it.
It still does not work for some reason…
When I tried doing sudo snap remove ubuntu-mate-welcome it came up with
snap "ubuntu-mate-welcome" is not installed
And if I tried sudo snap install ubuntu-mate-welcome --classic then it told me
error: cannot perform the following tasks:
- Setup snap "core" (6132) security profiles (cannot setup apparmor for snap "core": cannot load apparmor profile "snap.core.hook.configure": cannot load apparmor profile: exit status 1
apparmor_parser output:
Cache read/write disabled: interface file missing. (Kernel needs AppArmor 2.4 compatibility patch.)
Warning: unable to find a suitable fs in /proc/mounts, is it mounted?
Use --subdomainfs to override.

So… I tried both sudo snap install ubuntu-mate-welcome --classic --subdomainfs and sudo snap install ubuntu-mate-welcome --subdomainfs but it came up with
error: unknown flag `subdomainfs'
DESPITE SUGGESTING TO USE THIS FLAG BEFORE!?
Did I install this whole image incorrectly? Is the only way now to delete the image from the sd card, and flash it back again? Please say no…
