Hello. I have a question to ask you regarding Linux Ubuntu.
If you do a distribution upgrade of Linux Ubuntu v.11.10 64-bit from v.11.04 64-bit, can you ever lose ANY of the installed software that is:
(a) installed by default with (inherent with) the distribution of Linux Ubuntu?
(b) installed from Ubuntu Software Center (USC) whether by manual download files where USC will finish the install or found in the Ubuntu repositories of the USC interface and USC does the install?
(c) installed from Synaptic Package Manager?
(d) installed from Update Manager?
(e) downloaded manually (Ubuntu repositories and third-party repositories) and installed by Archive Manger (File Roller)?
(f) using Terminal with text based methods, like apt-get and Aptitude to install manually downloaded files?
(g) installing *.deb files from manually downloaded files using the programs GDebi and dpkg?
(h) using the web browser like Firefox's later versions of the built in AptURL protocol to install files?
I believe I have addressed every conceivable method files/programs/packages/software can be installed into Ubuntu to date. I am not positive if the installation methods make a difference with this issue or not? Please explain the different case scenarios where this may be an issue of a loss of installed software program via these means with an upgrade distribution.
If there is a loss of an installed software program, how can or does the user be alerted to know what software programs are removed or deleted during or after the Ubuntu distribution upgrade? Please explain.
