How to free up space on /boot partition?

Question

linux

Hello!
The /boot folder is on a separate partition, with a certain size. When trying to update / install packages, it turned out that this was impossible, because. there is not enough space in /boot to load new kernels.
The current kernel version is older than anything in the /boot folder. Those. there are no kernels older than the current one in the folder, and everywhere on the Internet they write to delete old kernels. Can I safely remove any kernels, not the latest ones?
Let's have it now

vmlinuz-4.4.0-31-generic
vmlinuz-4.4.0-38-generic
vmlinuz-4.4.0-42-generic
vmlinuz-4.4.0-45-generic
vmlinuz-4.4.0-47-generic
vmlinuz-4.4.0-51-generic
vmlinuz-4.4.0-53-generic
vmlinuz-4.4.0-57-generic
vmlinuz-4.4.0-59-generic
vmlinuz-4.4.0-62-generic
vmlinuz-4.4.0-63-generic
vmlinuz-4.4.0-64-generic

Is it possible to at least remove kernels greater than 4.4.0.31 (current) and less than 4.4.0.64 ?
Restarting the system is not possible, because. the site is spinning on the server, so maybe the kernel would have been updated.

Answer 1

apt autoremove
there is no tragedy to make a reboot

Answer 2

When apt and dpkg fail:
1. Boot from a LiveCD, such as PuppyLinux.
2. Mount boot-disk, for example, sba2.
3. Remove some cores that are not in use.
4. Boot normally and sudo apt-get autoremove
