When I try to update my system, it returns the following error:

serj@debianochka:~$ sudo apt update

As mentioned in comments by @Bodo, it looks like you reached a point where apt removed libnettle which is required to run ... apt.

Try to download the corresponding package for your architecture using https://packages.debian.org and install it manually using dpkg -i <path to the .deb>.

You can try with wget <URL> or curl <URL> > libnettle.deb.

If both curl and wget fail because they also depends on libnettle, then, try downloading it from another PC and use SSH to copy it.

Then, re-run apt-get install --fix-broken.
