Unable to install 4.15.0-47 kernel

[JardaPop]

Dear team,



I used on my PC Ubuntu 16.04 LTS system. Regularly I am updating and 
upgrading my system by command line apt update and apt dist-upgrade.

Everything went flawlessly up to upgrading to 4.15.0-47 kernel. I can see it
in synaptic but I am not able to uninstall it and by installing it once more
I always get this error message "linux-image-4.15.0-47-generic subprocess 
installed post-removal script returned error exit status 1"




I downloaded file linux-image-unsigned-4.15.0-47-generic_4.15.0-47.50_16.04.
1_amd64.deb but when installing it by means of GDEBI I get the error 
message: There is a conflict with the installed package "linux-image-4.15.0-
47-generic" (see enclosure). In grub I see no linux-image-4.15.0-47-generic 
but when I ran grub-customizer there are many kernels (see the enclosure).




What could be done in a wrong way from my side?




Thank you very much for your kind help.

Regards

Jaroslav Popelka
