When I started, I got the error that /usr/local/gap4r8/pkg/PolymakeInterface/PackageInfo.g is unreadable or does not exist (notice that it is a new package). However, the file does exist, but I found out that most files are owned by 50009 whoever that is (this was never a problem in previous versions). So I made this particular file readable for group users. Now I can start GAP and also the packages load, but the help system is broken:
