Trying to update Ubuntu 20.04.
I tried the solution in Cannot upgrade rsync following distribution upgrade to 20.04LTS
I tried to # sudo apt autoclean and receive warnings for packages:
dpkg: warning: files list file for package 'linux-hwe-5.8-headers-5.8.0-49' missing; assuming package has no files currently installed that I assume is normal after autoclean.
Corrently, I get the below error. Same result for sudo apt-get install --reinstall rsync
# sudo apt upgrade
...
dpkg: warning: files list file for package 'linux-modules-5.4.0-67-generic' missing; assuming package has no files currently installed<br>

I also tried to install libwebkit2gtk individually and endup with the same result.
# sudo apt-get install libwebkit2gtk-4.0-37
