Hi Damien,
Perhaps you can try to search for a first Linux course to get the minimum ... so after you can solve lot of things by yourself
suggest openclassroom ... French site :
https://openclassrooms.com/courses/repr ... e-de-linux
open a console (ssh) with root / your_admin_password
go to folder containing the file :
cd /usr/local/AppCentral/jdownloader/web/
save the original file (in case)
cp index.html index.html.ori
edit the file with
vi
vi index.html
... don't be afraid by the "^M" at end of each line it's a file for a Windows system where end of line are <CR><LF> in place of <LF> only for Linux
MOVE to the "colon" after http (
: )
USING THE ARROW KEYS to have your cursor ON IT (line 7)
then enter :
i (letter i )
s (to add the s to http) then
twice <esc> (escape ... twice to avoid problem with some terminal) NOW
http is replaced by
https ...
then
(colon and directly attached x ) to write and exit the file
.... a second http can be change but it's only a comment in case of error in the redirection (old browser), so feel free to change it or not)
if you have made an error ... just do :
<esc> twice the
:q! that cancel all change ...
it's ALL ... now you can test again the icon in ADM ...
Philippe.
