'Can't be read' errors
If you get an error message like
网页链接 exists but can't be read, the problem is file permissions. You can generally fix this by adding yourself to the 'boinc' group:
sudo usermod -a -G boinc $USER
exec su $USER
按照官网操作后没解决,重装再次尝试还是没解决,明天重装系统试试(之前是32位系统能运行,目前这是相同系统的64位,暂时不知道是否是这个原因)
