latest raspbian kernel update broke bash

Question

I just updated by raspbian box (stretch, upgraded raspbian-kernel, using it as console only) and somehow broke bash. Every time I try to log in (either by ssh or locally) I get the following error:

-bash: error while loading shared libraries: libc.so.6 ld-linux-arehf.so.3: cannot open shared object file: No such file or directory.

As I've understood I'll have to reinstall raspbian (ok got another SD card prepared for that, no prob) but I'd love to have my old files from that old SD card somehow transferred to another card.

Any ideas?

Answer 1

To backup old files from the old SD card attach it with a card reader to a computer ideally with a debian like operating system. Look with lsblk what device it uses. Usually it is /dev/sdb or /dev/sdc or something like. Mount its second partition:

pc ~$ sudo mount /dev/sdb2 /mnt

Now you have access to the old files:

pc ~$ sudo ls /mnt

Now you can copy your old files to where you want.
