You should be more careful when upgrading or fixing a security issue in the boot loader. It currently breaks a Debian Buster system, which is production. The suggested grub reinstall method did _not_ work for me. I booted from a USB stick into rescue mode and had to downgrade grub-common package (I don’t have grub2 on my system) and reinstall all dependent packages again. After downgrading grub-common/grub2-common to version 2.02+dfsg1-20, my system boots and works fine.<div class=""><br class=""></div><div class="">Downgrade grub-common/grub2-common:</div><div class=""><br class=""></div><div class="">from: 2.02+dfsg1-20+deb10u2</div><div class="">to:2.02+dfsg1-20</div><div class=""><br class=""></div><div class="">and it did work after reboot.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">See my APT history log for details.</div><div class=""><br class=""><div class=""><br class=""></div><div class="">“</div><div class=""><div class="">Start-Date: 2020-07-31 22:52:35</div><div class="">Commandline: apt install grub-common=2.02+dfsg1-20</div><div class="">Downgrade: grub-common:amd64 (2.02+dfsg1-20+deb10u2, 2.02+dfsg1-20)</div><div class="">Remove: grub2-common:amd64 (2.02+dfsg1-20+deb10u2), grub-efi-amd64-bin:amd64 (2.02+dfsg1-20+deb10u2), grub-efi-amd64:amd64 (2.02+dfsg1-20+deb10u2), shim-signed:amd64 (1.33+15+1533136590.3beb971-7), grub-efi-amd64-signed:amd64 (1+2.02+dfsg1+20+deb10u2)</div><div class="">End-Date: 2020-07-31 22:53:28</div><div class=""><br class=""></div><div class="">Start-Date: 2020-07-31 22:55:36</div><div class="">Commandline: apt install grub2-common=2.02+dfsg1-20</div><div class="">Install: grub2-common:amd64 (2.02+dfsg1-20)</div><div class="">End-Date: 2020-07-31 22:55:41</div><div class=""><br class=""></div><div class="">Start-Date: 2020-07-31 22:56:39</div><div class="">Commandline: apt install grub-efi-amd64-bin=2.02+dfsg1-20</div><div class="">Install: grub-efi-amd64-bin:amd64 (2.02+dfsg1-20)</div><div class="">End-Date: 2020-07-31 22:56:53</div><div class=""><br class=""></div><div class="">Start-Date: 2020-07-31 22:57:09</div><div class="">Commandline: apt install grub-efi-amd64=2.02+dfsg1-20</div><div class="">Install: grub-efi-amd64:amd64 (2.02+dfsg1-20)</div><div class="">End-Date: 2020-07-31 22:57:33</div><div class=""><br class=""></div><div class="">Start-Date: 2020-07-31 22:58:43</div><div class="">Commandline: apt install grub-efi-amd64-signed=1+2.02+dfsg1+20</div><div class="">Install: shim-signed:amd64 (1.33+15+1533136590.3beb971-7, automatic), grub-efi-amd64-signed:amd64 (1+2.02+dfsg1+20)</div><div class="">End-Date: 2020-07-31 22:58:50</div><div class="">“</div><div class=""><br class=""></div><div class="">My kernel is: 4.19.0-9-amd64</div><div class="">No grub2.</div><div class="">grub-common, grub2-common is now at v2.02+dfsg1-20. </div><div class="">Debian Buster latest v10.4. </div><div class="">Linux package: linux-image-4.19.0-9-amd64-signed v4.19.118-2+deb10u1</div><div class="">I have working UEFI booting system, w/o secure boot and amd64 grub package UEFI signed by Debian. </div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Kind regards,</div>--<br class=""><div class="">
