Install Updates could not fetch the package cache information lists

[LinuxLaie2019]

When I try to update Linux Light I always get the error message below. I have used the install button on the start linux light screen and I tried it also with "apt-get update".
The update procedure worked for quite a while without problems. I have recently installed gimp and the opera browser. May be the problem is caused by these newly installed programs.
Suggestions how to solve the problems appreciated...
