освободить место в / boot? [дубликат]

Я нуб в linux.

Я пробовал следующие команды:

sudo bootnukem

sudo apt-get autoremove

dpkg -l linux- {image, headers} - «[0-9] *» | awk '/ ^ ii / {print $ 2}' | grep -v -e uname -r | вырезать -f1,2 -d "-" | grep -e '[0-9]' | xargs sudo apt-get -y purge

Проблема:

sudo apt-get autoremove

You might want to run 'apt-get -f install' to correct these.

E: Unmet dependencies. Try using -f.

При попытке установить его не удается установить, не остается места.
