ubuntu-18.04

问题 Both Python 2.7 and 3.6 are installed by default in Ubuntu 18. But I wish to use the Anaconda Python with conda package manager. To avoid any conflicts I wish to completely remove the default Python 3.6. Are there any way to do that? Please help. 回答1: Ubuntu 18.04 requires python 3.6 to function. If you remove python 3.6, you won't be able to log in after a restart. Ubuntu will still have python 3.6minimal, even after uninstalling python 3.6. so you will have to remove both. Once that is done

问题 Publii is a desktop-based CMS for Windows, Mac and Linux. I downloaded the appimage and deb packages and installed it, but neither seems to be launching, I have no way to troubleshoot why it isn't launching and I have used this software before on a previous installation of Ubuntu How would I troubleshoot this program in Linux effectively? I'd prefer a terminal approach but a GUI is also good. EDIT following the instructions ran here npm run dev > Publii@0.31.3 dev /home/areahints/Publii >
