As long as you download it from the official UbuntuMATE for Raspberry Pi 2 download page, you ought to be fine.
Just downloaded the image again via its torrent file 2 days ago, flashed it to my microSD card, and could run the UbuntuMATE installer on my RPi 2 device without any problems.
whenever I try to install, the resoloution is all off for my monitor, making it frustratingley unusable.
please help!
Take a look at /boot/config.txt there are options in there for setting the resolution of the monitor.
Now it just boots into emergency mode, after I reinstalled the image. Will someone pease help?
I noticed one of the changes of the new version of Mate 15.10 is a slightly updated kernel, as the changelog states:
Updated to Linux 4.1.15 (previous one was 4.1.13)
But I also noticed that the repositores have a version 4.2.0 of the kernel for the Raspberry Pi. This one is probably coming from Ubuntu (the company) as I can see kernels for the Nexus 5 as well for example.
Has anyone tried upgrading the Ubuntu Mate kernel to the 4.2.0 version in the repositories? If yes, did it work? I am curious if anyone has tried that. I may try it myself too once I get an additional MicroSD card.

Checking the official RPi-Firmware repository today, it is still bumped up to version 4.1.16 for the RPi devices. Guess, it will take a short while though to release 4.2
This said, you can always use the command âsudo rpi-updateâ to update to the latest official RPI kernel release.
Nice job, better for our middle school than Raspbian Jessie. Two main issues for your next release: please make the date / time update automatic, we could n´t even get into Wikipedia due to the wrong system date.
Second is get Raspberry hardware acceleration inside Firefox and VLC some how. The speed of omxplayer is good but the interface is too different; Epiphany on Raspbian was up to speed but again the different interface (bookmarks etc.).
On time synchronisation, because the Pi doesnât have a battery, the system time is lost when the Pi is powered off. When you turn the Pi back on, it takes a while for the ntp daemon to synchronise the time. If you install ntpdate, the time is synchronised as soon as the network interface comes up. To install ntpdate from a terminal, run apt-get install ntpdate
I read recently that ntpdate has been deprecated, which means it will stop being maintained at some point.
From UbuntuMATE 15.10 onwards, time synchronisation with Internet sources can be handled with âsystemdâ.
Have a look in my post about âUbuntuMATE 15.10 reset RTC chip date & time during bootupâ, on the second described approach that also works without an RTC chip using only the âtimesyncdâ daemon and operates only when network connectivity is available, thus removing the complexity of NTP 
Hello and thank you for creating a fantastic OS for the Raspberry Pi.
I have it running on a raspberry Pi 2 with the official 7" touchscreen. Ubuntu MATE works much better than the Raspbian install that i have been using and the interface just seems more responsive.
I have an issue with the accessibility âsimulate right-clickâ that is normally available in Ubuntu. I have seen lots of screenshots of the âsecond tabâ in the mouse config, but in MATE, it is just not there.
The assistive technologies are there, but i do not see anything to turn on the âsimulate right click, by holding down left clickâ which should be an option. Any help with finding the right-click, using a left long-click, would be super!
as an additional thing, some of the config screens are too big for the resolution of 800 x 480, but i have got around that by using a bluetooth keyboard and using left-alt and left-mouse click to drag the top of the config screens off the top of the desktop, enabling me to see the bottom of the window. A touchscreen option would be great for that but it is early days yet. 
Are there any plans for a 64 bit build to support the Raspberry Pi 3?
See here about a 64-bit build:
I get scrambled audio from Pandora and YouTube with this, but raspbian works fine. It doesnât matter if I am using analog, USB audio, or HDMI.
This is what I am dealing with: https://vimeo.com/159695009
Canât boot. Had no problems creating the boot disk, in fact I did it both ways: command line and GDisk. Boot starts right of with a kernel panic - not syncing, then about another dozen lines of errors and ends with: random: nonblocking pool is initialized.
If you need me to post a picture just let me know.
Any help would be appreciated! Thanks.
Just tried 16.04 on my new Pi 3 and found that it lacks integrated RDP or VNC and doesnât support SSH via PuTTY for the headless startup I require.
I notice that âlinux-image-4.2.0-1028-raspi2â is available. How to install it (headless)? I have MATE 15.10 on raspi2 and tried the usual sudo apt-get update, upgrade, dist-upgrade: 0 updates.
Then I just installed the package: sudo apt-get install linux-image-4.2.0-1028-raspi2. This causes some updates.
However after a reboot or 2, the shell still welcomes me with âWelcome to Ubuntu 15.10 (GNU/Linux 4.1.15-v7+ armv7l)â?
xrdp (uses X and VNC as backend)ssh (also available in the Software Boutique). No reason why it wouldnât work with PuTTY.
sudo apt-get install xrdp ssh
@bronze, as far as Iâm aware, Raspberry Pi kernel updates need to be performed by typing:
sudo rpi-updateMy problem is that there is no way to do that headless which is the only means I currently have for accessing a Pi. The latest Raspbian is pre-configured with ssh installed so one can do a headlless bootstrap using PuTTY from a PC and I would like to see the same with this distribution.
Eliminating the need to have a keyboard/display to get this up and running would be a very good thing. Thanks.
Thx, I am now welcomed by âWelcome to Ubuntu 15.10 (GNU/Linux 4.1.21-v7+ armv7l)â.
