我已将 Ubuntu 版本更新至 18.04。现在,当我尝试通过 /opt/pt/bin/PacketTracer7 启动 Packet Tracer 时,我收到很多这样的消息:
"Warning: libpng warning: iCCP: known incorrect sRGB profile"
我也得到了那些:
QFSFileEngine::open: No file name specified
"INFO - Qt Version: 5.5.1"
QFSFileEngine::open: No file name specified
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
QT_SCREEN_SCALE_FACTORS to set per-screen factors.
QT_SCALE_FACTOR to set the application global scale factor.

Warning: libpng warning: iCCP: known incorrect sRGB profile
Warning: QObject::connect: No such slot CLogicalToolbar::showViewport()

我也尝试了 gitgudgithub 的答案:Ubuntu 18.04 上的 Packet Tracer 7 无法启动。结果收到此消息:
error while loading shared libraries: libicui18n.so.52: cannot open shared object file: No such file or directory
问题是我安装了 libicu60。我不知道该怎么做。有什么办法可以解决这个问题吗?

已修复!只需安装另一个版本的软件包。然后只需执行

一切都会顺利!
