I just migrated a linux system (Ubuntu 16.04) from a failing hard disk. After lots of troubles, it starts up, but always complains

/dev/sda2 has unsupported feature(s): metadata_csum
E2FSCK: Get a newer version of e2fsck!

So I updated e2fsck to 1.44.4 on my root file system.

e2fsck 1.44.4 (18-Aug-2018)
Using EXT2FS Library version 1.44.4, 18-Aug-2018

Still I get the above error.

So my question is: From where is e2fsck run at startup? It appears not to be the root partition. Do I have to update e2fsck on the initramfs? Is it possible that reinstalling grub2 updates e2fsck on the initramfs? Reinstalling grub2 did not solve this issue.

Read this very detailed Ask Ubuntu post :
E2FSCK: how to handle the “metadata_csum” error by advancing the e2fsck version beyond default installed version

The final advice given is :

update e2fsprogs and e2fslibs to 1.43.X - do not go all the way up to 1.44.X. The 1.43.X packages are sufficient to remove the "metadata_csum" error and allow you to use GParted or e2fsck at the command line.
