There are old versions of some system packages for:
- Header files related to Linux kernel version 3.11.0
- Linux kernel headers for version 3.11.0 on 64 bit x86 SMP
- Linux kernel extra modules for version 3.11.0 on 64 bit x86 SMP
I selected them which could be seen in the screenshot and they are 516 MB in total. Should I remove them manually or will they be removed automatically later? If they are not necessary, which command(s) will remove just old versions of multiple packages completely?
