Description

Select a Grass 7 tool, e.g v.split.length, r.aspect
Error message: Missing dependency. This algorithm cannot be run :-(
It seems that GRASS GIS 7 is not correctly installed and configured in your system. Please install it before running GRASS GIS 7 algorithms.
Console output: ERROR: option <output>: </tmp/processinge1c274c67147466d8f674e4a73e37a95/734717ba89834cb895be30f61d6e4555> exists. To overwrite, use the --overwrite flag

It appears that the tool runs through some diagnostic steps involving creating various files. This fails when the same filename is reused and the overwrite flag is not provided.

Just tested on both the described OSes (same versions) and cannot confirm. Using QGIS installed from QGIS with ubuntugis dependencies.

Please check in ~/.qgis2/python/plugins

you have a "processing" folder, is yes delete, restart qgis and try again.

Removing the processing folder worked.
rm -Rf ~/.qgis2/python/plugins/processing*
