Como faço para remover kernels antigos apesar do uso de 100% de inode em / usr?

Eu estava tentando atualizar meus pacotes hoje:

$ sudo apt-get upgrade

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 linux-headers-3.16.0-44-generic : Depends: linux-headers-3.16.0-44 but it is not installed
E: Unmet dependencies. Try using -f.

Então, fui em frente e tentei apt-get -f install :

$ sudo apt-get -f install

The following extra packages will be installed:

Está reclamando dizendo No space left on device . df -Th me diz que há espaço suficiente:

$ df -h

/dev/sda6       3.3G  2.5G  571M  82% /

/dev/sda9       256G  9.6G  233G   4% /var

No entanto, df -i me diz que /usr esgotou todos os inodes.

Estas são as dirs e seu uso de inode:

/usr/bin = 2846
/usr/etc = 1
/usr/games = 8
/usr/include = 3204
/usr/lib = 42317
/usr/local = 105
/usr/lost+found = 1
/usr/sbin = 306
/usr/share = 228141
/usr/src = 348704

Portanto, se eu puder limpar /usr/src (que contém os kernels atual e antigo), provavelmente poderei resolver o problema. Mas continuo correndo para o primeiro erro:

$ sudo apt-get purge linux-image-3.8.0-35-generic 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-headers-3.16.0-44-generic : Depends: linux-headers-3.16.0-44 but it is not going to be installed
 linux-image-extra-3.8.0-35-generic : Depends: linux-image-3.8.0-35-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Alguma sugestão sobre como posso remover meus kernels antigos? Obrigado!

Eu estava ficando sem opções e tempo, então tentei e funcionou:

Eu descobri que kernel eu estava usando:

$ uname -r
3.16.0-44-generic

Eu decidi mover os kernels realmente antigos para o meu armazenamento externo:

sudo mv linux-headers-3.8* /media/housni/linux-headers

df -i mostrou que uma quantidade significativa de inodes foi liberada, então eu rapidamente desinstalei os cabeçalhos que eu sabia que não precisaria:

sudo apt-get purge linux-headers-3.8*

Depois disso, atualizei o grub e reiniciei

sudo update-grub2 && sudo shutdown now -r

Eu então fiz uma limpeza extra, como limpar meu cache ( sudo apt-get clean ) e executar autoremove ( sudo apt-get autoremove ) apenas para estar seguro e agora tudo parece estar de volta ao normal:)
