After upgrading to 19.04 from 18.10 - I've started seeing an error revolving around linux-image-4.18.0-24-generic and seems to cause me from updates as well updating grub of course... Has anyone experienced this or can anyone guide me as to how to repair this issue ?

After running this command "sudo apt update && sudo apt upgrade" I then receive this error in the terminal -

"Do you want to continue? [Y/n] y

Also when attempting to do a partial upgrade it says that kernel isnt installed and fails out

UPDATE: As requested I am posting the output of each command here

update 2 : After moving both files as suggested here is the output using sudo apt-get upgrade

  • Before you proceed with my answer below please add output of dpkg -S /etc/grub.d/bin/grubcfg_proxy (find package for problematic file), ldd /etc/grub.d/bin/grubcfg_proxy (list its dynamic-libraries), which grub-customizer (find path of related GRUB Customizer file), apt-cache policy grub-customizer (get version of GRUB Customizer package) to the question. – N0rbert Aug 24 at 9:01

The analysis of source code says that grubcfg_proxy is related to grub-customizer package.

At first I can't find the reason why it is located in /etc/grub.d/bin/grubcfg_proxy on your system. This was actual for old versions, but not for current versions.
At second it is strange that it tries to load libcrypto.so.1.0.0, while regular Ubuntu 19.04 has libcrypto.so.1.1 (shipped with libssl1.1 package).
The third moment is that grubcfg_proxy file on disco is renamed to grubcfg-proxy and located in /usr/lib/grub-customizer/grubcfg-proxy.

So I'll suggest to move your binary file out the way with

sudo mv /etc/grub.d/bin/grubcfg_proxy ~/

then to be completely sure I'll recommend to purge current version of GRUB Customizer with

sudo apt-get purge grub-customizer

then update GRUB configuration:

sudo update-grub

and finally install upgrades:

sudo apt-get upgrade

If you need to use grub-customizer install its package from official repository with

sudo apt-get install grub-customizer

and use it as before.

  • I'll suggest to move these files out the way with sudo mv /etc/default/grub.d/init-select.cfg ~/ and sudo mv /etc/grub.d/10_linux_proxy ~/ . And then rerun sudo update-grub. – N0rbert Aug 26 at 11:50
  • after moving both files : sudo update-grub - using custom appearance settings /etc/grub.d/21_memtest86+_proxy: 3: /etc/grub.d/21_memtest86+_proxy: /etc/grub.d/bin/grubcfg_proxy: not found Found memtest86+ image: /boot/memtest86+.elf – zerotechz Aug 26 at 12:19
  • I've also added output of sudo apt-get upgrade after moving both files up above as an update.. My apologies at the clutter as I'm still getting used to proper formatting. – zerotechz Aug 26 at 12:43
  • sudo mv /etc/grub.d/*_proxy ~/, then sudo update-grub – N0rbert Aug 26 at 13:14

I experienced the same problem with grubcfg_proxy not finding libcrypto.so.1.0.0 in an expected location, during the cleanup phase of updating from ubuntu 18.04 to 19.04.

I posted my fix on the related shared library missing question here:

Ubuntu 18.04: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory
