[Qgis-user] Fail to combine and cut tools

[Miguel Angel Adrados Polo]

Good morning.
I have installed Qgis 3.10 on a Linux system (Ubuntu). I try to run two GDAL algorithms:
1. COMBINE SIX DEM IMAGES
and
2.- CUT RASTER BY MASK LAYER
It doesn't work in either case and these are the error messages returned by the log:
2020-04-27T13:02:52     INFO    gdal_merge.py -ot Float32 -of GTiff -o /home/miguel/Escritorio/prueba.tif --optfile /tmp/processing_013003f3802c4b7f91d95567155a3f88/065a4c31bd234960b77dea3e8e96055a/mergeInputFiles.txt2020-04-27T13:02:52     INFO    GDAL execution console output             /bin/sh: 1: gdal_merge.py: not found           2020-04-27T13:04:57     INFO    gdalwarp -of GTiff -cutline /home/miguel/Documentos/Mapas/Ubiña_Vegarada_50k/CapasUbiñaVegarada50k/Marco50.shp -cl Marco50 -crop_to_cutline "/home/miguel/Documentos/Mapas/Ubiña_Vegarada_50k/MDT IGN/PNOA_MDT25_ETRS89_HU30_0077_LID.asc" /tmp/processing_013003f3802c4b7f91d95567155a3f88/13568660cf77452fa0ea5bb9e7d52b9c/OUTPUT.tif2020-04-27T13:04:57     INFO    GDAL execution console output             ERROR 1: Cannot compute bounding box of cutline.             Thanks and regardsMiguel
