It’s surprising since the new image has been tested on the RPi B by @kload and worked well.
I think the issue is not from the installation itself, but the upgrade of mysql-server.
If you want to be sure of that, grab the old yunohost image and try to install it on your raspberry. See if there is no issue.
There is this one yuno rpi September 2014, and you can find other ones over there build yunohost. You’ll have a lot of updates for sure, but you can previously run them on your desktop with qemu, if you want.
Thanks, I’ll give it a try. BTW, is there a difference between installing your premade images and installing Raspbian and then Yunohost with the dedicated script? Just to know if it’s worth trying that other option in case the sept. 2014 image fails to upgrade too.
Tried the new image and after a bit of a mess (installation apparently stuck, turned the Pi off and on again, re-installation that triggered two or three reboots), it goes to the login screen but the system can’t find the network connection. During boot, it complains that it can’t find eth0 and indeed, after login, ifconfig doesn’t show it; only the loopback interface. The /etc/network/interfaces file seems ok.
Note that during boot, I have a message saying something like “eth1 copied from eth0”, not sure if it’s relevant as there isn’t an eth1 either in interfaces or reported by ifconfig.
EDIT: I have a bit of a doubt: is it a new “beta” image? Is it a new version that happened to be released yesterday and wasn’t as a reply to my issues at all?
EDIT 2: maybe the eth0 interface missing is a consequence of switching from bind9 to dnsmasq?
It’s a quite random issue, we never now when and why it’s happening.
You can try to fix it by mounting your SD-card on your desktop computer, and go to the etc/networki/interfaces file, and change eth0 to eth1.
