Extreme error output during routine update

Support
1

Software update produced over 1100 lines of error output during a routine update.

In years of working with manjaro (and archlinux) I have never seen anything like this.

Full output at https://pastebin.com/x2db9ZMA

Unclear on what happened and what to do…?

Sample:

Warning: cuda: /etc/ld.so.conf.d/cuda.conf already existed in filesystem
It has been backup to /etc/ld.so.conf.d/cuda.conf.old
Warning: cuda: /etc/profile.d/cuda.sh already existed in filesystem
It has been backup to /etc/profile.d/cuda.sh.old
Warning: cuda: /opt/cuda/CUDA_Toolkit_Release_Notes.txt already existed in filesystem
It has been backup to /opt/cuda/CUDA_Toolkit_Release_Notes.txt.old
Warning: cuda: /opt/cuda/DOCS already existed in filesystem
It has been backup to /opt/cuda/DOCS.old
Warning: cuda: /opt/cuda/EULA.txt already existed in filesystem
It has been backup to /opt/cuda/EULA.txt.old

cuda is an unknown to me. Don’t have it. Google search says its related to Nvidia.
This is a warning messages. Anything in log files. ‘dmesg’ errors after reboot?

Usually ‘exists on filesystem’ occurs when software has been manually installed (from outside the repos).
But usually it would not recover (or automatically overwrite and create ‘.old’) on its own.

It looks like pamac has this functionality now … the question still remains why you had these conflicts in the first place…

CUDA is a parallel GPU processing unit. I use it for folding@home. This is a backup system for my archlinux which normally runs folding@home. It runs on my GTX 1070 Ti.

Since I have not installed ‘CUDA’ manually, it is some kind of snafu with installation/update.

Since it is a backup and not really necessary I will deprecate it on manjaro.
