in this case of message « erreur d’écriture: Relais brisé (pipe) » your terminal shows you the duplicated lines in your apt package
having this information (lines duplicated)
go to
cd /etc/apt
then check in the file sources.list and commant the duplicated line by adding # at the beginning of the line
- it may be your duplication is between the file sources.list and a file under sources.list.d
in this case:
- if you have an alternative so modify one of the lines in sources.list or the file in sources.list.d
- if you dont have an alternative so you should ignore one of them by deleting the file in sources.list.d mentioned in the terminal or by commenting the line in sources.list
destinations:
sources files ===> /etc/apt/sources.list
decomposed files sources ===> in the folder /etc/apt/sources.list.d
i hope i have helped ^^
