LubuntuSoftwareCenter looses list of selected Software if 1item source not trusted
Ultimate Edition LXDE-netbook desktop Lubuntu Software center; selected 15 items for installation basket, one´s sources were not trusted, so none would install, deselection of single item doesn´t work, whole basket is empty --

would be nice to have the option to deselect single items from list in future versions or possibility to install the untrusted item anyway

UE had apt-get last I checked, and it does not care if it's trusted or not, as long as the repo is in the /etc/apt/sources.list file. Start with these two. and . .

Search on techieMoe and "How to Install Software in Linux"

Oh! Yours was just a criticism, OP? If so, take it to the UE Forum.

hi hilyard; thank you for your message(s) ! that will give me an orientation in which direction to do research;
Yes, it it is apt-get and i will look for a way to make apt-get accept the source; and thank you, too for the idea to take it to the UE forum; sometimes (...) i tend to forget the obvious... no idea what you want to say with OP... in my world OP refers to the section of a hospital where surgery is done...would be nice to have something like a general glossar for IT abbreviations somewhere...IT in the sense sense of Information Technology (guess)
thank you for mentioning techie moe ... curious what it might be... so, now (then) have a look on how to add repos... that should be simple to achieve and try out thank you !!

OP stands for "Original Poster" or the one beginning a thread (this is what you did in posting the first).

The file structure of GNU/Linux is 98%+ uniform no matter what distro used. The /etc/ directory is directly off root ( / ) and contains system configuration files, on the whole. The path to the file needed to modify which repositories (repos) are to be used by APT resides in /etc/apt/ and is named sources.list. This is what is needed in order to assure software packages desired can be installed. They must reside in the repo before they can be downloaded and installed.

techieMoe is a well-known Linux guru who reviewed distros and such in the past and is well-respected in Linux circles. He wrote a definitive How2 in another (unnamed here) forum. This is a reference I, myself, use from time to time. I pass it on to you.

There is a geek dictionary online out there, somewhere (I forget the URL) or go to a wiki for quick reference.

Your text editor is probably gedit ; so, to edit the list of repos the command in your hypothetical case you would issue at the terminal would be
PHP Code:

sudo gedit /etc/apt/sources.list 

Sample sources.list
PHP Code:

deb precise-security main restricted
deb-src precise-security main restricted
deb precise-security universe
deb-src precise-security universe
deb precise-security multiverse
deb-src precise-security multiverse
