Problems with copy-paste/root terminal

[skidoo]

Something is wrong the arrow,

given vague "clues" like this ----^
troubleshooting will probably be impossible.

suggest: Start over. Remove whatever piecemeal xfce components you had installed,
then install the xfce metapackage: sudo apt-get install xfce

[keos]

no, something is very wrong ...

keos@kaos:~
$ sudo apt-get install xfce
Reading package lists... Done

E: Unable to locate package xfce

sudo apt-get install xfce4

Maybe you better use the metapackage-installer

You still didn't answer which release you use

lsb_release -dic

[skidoo]

E: Unable to locate package xfce

this suggests you just forgot to sudo apt update prior to attempting the install

[keos]

Nop i did it.

Any way ... it is already uninstalled.

Thanks.
