Errors were encountered while processing:
linux-firmware
E: Sub-process /usr/bin/dpkg returned an error code (1)
Problem might be that /boot is at 90% full. But how can I free space if autoremove does not?
uname -r shows: 5.4.0-70-generic
and /boot content is as follows:

Question: which of these files can be safely removed, if apt autoremove does not on its own?
