Hello, I am using lubuntu 18.04 LTS. After installation all looked good and even I installed some softwares using deb pakage and software center and those softwares are still working. But after some days it seems impossible to install any software from software center. When I try to install any software it shows progress bar and after a few seconds it shows that software is installed. But when I click the lunch option the software doesn’t open and nothing happens. Moreover after restarting my pc I cannot find that software in the installed software list.
Can anybody please help me in this situation?
Thanks to all.
