Michaaa62, I did same cleaning or should I say deleting some file and folders and suddenly everything went back to be fine and normal. I can install again as normal, I can update and so on. Just as you said the phone was full and needed some cleaning. Hopefully that was the problem. What I found strange this time is that when I executed the command in X terminal like you said and then went to view the disk_usage.txt file I saw that the file is empty. Nothing, blank. So I thought I did something wrong and tried the earlier commands in you earlier post (#14 and #18) here in this tread and they came out with the same results. The files were all totally empty. Strange. Since I don´t have my phone with me right now I cannot try it again but I will later today just to see, perhaps I did something wrong after all. Nevertheless I thank you for all the help.
