Ubunti installation oddness

#1 · 1. März 2020, 2:00

Yo,

Install needs sudo, but I'm seeing some strange behaviour. It creates a Prism folder in home that has root ownership.
Meaning I cannot save settings changes, if I try to add packages setup for Houdini for example, it's throwing a bunch
of errors. Here is just a snippet.

"/home/lewis/programs/Prism_v1.2.0_Linux/Prism/Scripts/PrismCore.py", line 2320, in setConfig

with open(configPath, "w") as inifile:

IOError: [Errno 13] Permission denied: '/home/lewis/Prism/installLocations.in

That makes sense as ownership is root.

Trying to launch PrismTray results in : Could not launch PrismTray

Trying to save settings also results in: Permission denied: /etc/xdg/autostart/PrismTray.desktop Try to execute this tool as root.
It has the same issue, it's owndership is set to root for some reason.

Any thoughts on why it's installing with those permissions, etc?

Cheers

Lewis

Hey Lewis thanks for the feedback,

Prism needed sudo permissions to setup the Prism startmenu and to setup the autostart of the Prism tray when you start your system.

However I just updated Prism to v.1.2.1.57 and now you can install Prism without sudo permissions. In that case the startmenu and the autostart setup will be skipped.

The problem with the root permissions on the Prism preferences files didn't occur on Centos, so I guess it occurred only on newer Ubuntu versions. But that's fixed now in the new Prism version.

The reason why you can't launch the Prism tray is that tray icons are not fully supported on Ubuntu 18, but there are some workarounds, which you can try:

https://askubuntu.com/questions/1056226/ubuntu-budgie-18-04-lts-system-tray-icons-not-all-showing

The file /etc/xdg/autostart/PrismTray.desktop is in a folder, which requires root permissions. I removed the popup when you save the Prism Settings and instead I added a small note to the autostart checkbox, that it can be changed only with root permissions.

It should be a lot easier to install Prism on linux now.

Cheers
