Goodmorning everyone. My problem is on initramfs-tools on Ubuntu 15.10 Mate uploaded Raspberry Pi 2
Some of you can tell me what are these libraries?
What are they?
When upgrading is always presented this problem. I tried it with sudo -u -k -all but the answer is generating /boot/initrd-3.18.0-25-rpi2
and then unsupported platform.
How can you solve this problem? Thank you. 
Ubuntu MATE 15.10 doesn’t come with that kernel version. I’m guessing you’ve dist-upgraded from 15.04? Which is sadly not supported.
Thanks for your answer. I am not very expert, but what are these tools?
What do you recommend I do?
Yes, it’s true. I upgraded to the latest version. 
Since you’ve upgraded from 15.04 to 15.10 on the Raspberry Pi, which due to its architecture is not supported, your best bet would be to save/backup any data you wish to keep, then re-flash the card with a fresh image of 15.10.
