As in the topic i have to free some space at boot, but don't really know how. I'm pretty new to ubuntu, only understand few commands, and I found one solution to delete all unused kernels (I'm sure I have few since there are a lot of files in boot), but don't know how. I found the command to delete them but for different versions (?) and can't redo it by myself. Here is list of files in boot.
abi-4.2.0-34-generic initrd.img-4.2.0-42-generic
abi-4.2.0-35-generic lost+found
abi-4.2.0-36-generic memtest86+.bin
abi-4.2.0-38-generic memtest86+.elf
abi-4.2.0-41-generic memtest86+_multiboot.bin
abi-4.2.0-42-generic System.map-4.2.0-34-generic
config-4.2.0-34-generic System.map-4.2.0-35-generic
config-4.2.0-35-generic System.map-4.2.0-36-generic
config-4.2.0-36-generic System.map-4.2.0-38-generic
config-4.2.0-38-generic System.map-4.2.0-41-generic
config-4.2.0-41-generic System.map-4.2.0-42-generic
config-4.2.0-42-generic vmlinuz-4.2.0-34-generic
grub vmlinuz-4.2.0-35-generic
initrd.img-4.2.0-34-generic vmlinuz-4.2.0-36-generic
initrd.img-4.2.0-35-generic vmlinuz-4.2.0-38-generic
initrd.img-4.2.0-36-generic vmlinuz-4.2.0-41-generic
initrd.img-4.2.0-38-generic vmlinuz-4.2.0-42-generic
initrd.img-4.2.0-41-generic
And here is the command i found:
sudo apt-get purge linux-image-{3.0.0-12,2.6.3{1-21,2-25,8-{1[012],8}}}
Can anyone help me redo it for my files ? And maybe explain it a bit ? Thanks in advance guys.
