I installed synaptic package manager to manage my packages and, I see many kernels, that are not being used, can I delete them? There are 2 - 3 using kernels and many non using.

My /boot partition is nearly full and I get a warning every time I reboot my system. I already deleted old kernel packages (linux-headers...), actually I did that to install a newer kernel version that came with the automatic updates.  After installing that new version, the partition is nearly full again. So what else can I delete? Are there some other files associated to the old kernel images?  Here is a list of files that are on my /boot partition:  :~$ ls /boot/ abi-2.6.31-21-generic         lost+found abi-2.6.32-25-generic         memtest86+.bin abi-2.6.38-10-generic         memtest86+_multiboot.bin abi-2.6.38-11-generic         System.map-2.6.31-21-generic abi-2.6.38-12-generic         System.map-2.6.32-25-generic abi-2.6.38-8-generic          System.map-2.6.38-10-generic abi-3.0.0-12-generic          System.map-2.6.38-11-generic abi-3.0.0-13-generic          System.map-2.6.38-12-generic abi-3.0.0-14-generic          System.map-2.6.38-8-generic boot                          System.map-3.0.0-12-generic config-2.6.31-21-generic      System.map-3.0.0-13-generic config-2.6.32-25-generic      System.map-3.0.0-14-generic config-2.6.38-10-generic      vmcoreinfo-2.6.31-21-generic config-2.6.38-11-generic      vmcoreinfo-2.6.32-25-generic config-2.6.38-12-generic      vmcoreinfo-2.6.38-10-generic config-2.6.38-8-generic       vmcoreinfo-2.6.38-11-generic config-3.0.0-12-generic       vmcoreinfo-2.6.38-12-generic config-3.0.0-13-generic       vmcoreinfo-2.6.38-8-generic config-3.0.0-14-generic       vmcoreinfo-3.0.0-12-generic extlinux                      vmcoreinfo-3.0.0-13-generic grub                          vmcoreinfo-3.0.0-14-generic initrd.img-2.6.31-21-generic  vmlinuz-2.6.31-21-generic initrd.img-2.6.32-25-generic  vmlinuz-2.6.32-25-generic initrd.img-2.6.38-10-generic  vmlinuz-2.6.38-10-generic initrd.img-2.6.38-11-generic  vmlinuz-2.6.38-11-generic initrd.img-2.6.38-12-generic  vmlinuz-2.6.38-12-generic initrd.img-2.6.38-8-generic   vmlinuz-2.6.38-8-generic initrd.img-3.0.0-12-generic   vmlinuz-3.0.0-12-generic initrd.img-3.0.0-13-generic   vmlinuz-3.0.0-13-generic initrd.img-3.0.0-14-generic   vmlinuz-3.0.0-14-generic   Currently, I'm using the 3.0.0-14-generic kernel.

I've upgraded to Ubuntu 12.04 and did it . I didn't look at the "packages to remove" section before clicking next - I've done Ubuntu upgrades many times and assumed it was just the normal set of obsolete library packages etc. But I do tend to watch the terminal text go by and see what it's doing, and I saw it removing a number of packages I wanted. I guess these are packages that aren't on the CD that can't co-exist with the new Ubuntu.  Anyway, I want to find which packages have been removed. So does the update log get saved somewhere?  Then I can start doing some grepping on it and then reinstall the packages I did want.

I used Ubuntu&nbsp;14.04 (Trusty Tahr) for about a year (actually upgraded it from Ubuntu&nbsp;12.04 (Precise Pangolin)), and during the time I installed some packages, and removed some other packages.  Now I think it's probably time to clean up the system as it's likely several unused stuff is lying out there (both from the old 12.04 and the new 14.04), and I hope to have a cleaner system that works faster.  I found these two links:       Both links seem good, but when I came across to what they said about Bleachbit then one says yes, and one says no - a bit contradicting.  What should be done for this common task?

I'm on a CentOS machine. I updated and installed some packages a few weeks back, but I don't remember the name of every package or the names of every dependency. I used yum.  Can I list the packages on my system by the date they were last installed or updated?

As time goes by we tend to do apt-get install and add or replace software.  Are these archived in some form or do they get auto-cleared after installation? And if it doesn't get auto-cleared, it would mean that a clean up is needed, isn't it?  Finally, if they're not auto-removed, can we reuse these packages on different machines?

This is exact content from my sources.list:  #  # deb cdrom:[Debian GNU/Linux 2016.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160830-11:29]/ kali-rolling contrib main non-free #deb cdrom:[Debian GNU/Linux 2016.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160830-11:29]/ kali-rolling contrib main non-free   I couldn't install the Synaptic package manager and was told to modify sources.list.  I googled a lot and added some repos into it and ran update and upgrade command only to see Kali crash... I had to recover it.  Please mention the exact content that should be there to ensure that Kali Linux works.

We have some Ubuntu 16.04 servers. unattended-upgrades are automatically enabled since 16.04 and /boot is a separate partition. Due to the automatic security updates, the boot partition is running out of space with new kernels. We can't reboot the systems (for availability reasons), so the machine is still using the penultimate kernel. Which kernels should I remove? All but the current, the oldest and the newest? Do you guys have some recommendations? I have also noticed that the newest kernel has the status &quot;Half Configured&quot;. This kernel would probably not work, so should I remove this one and use an older kernel? Output of dpkg -l | grep linux-image: ii  linux-image-4.4.0-21-generic --&gt; old kernel ii  linux-image-4.4.0-34-generic --&gt; current kernel ii  linux-image-4.4.0-36-generic --&gt; new kernel ii  linux-image-4.4.0-38-generic --&gt; new kernel ii  linux-image-4.4.0-42-generic --&gt; new kernel ii  linux-image-4.4.0-45-generic --&gt; new kernel ii  linux-image-4.4.0-47-generic --&gt; new kernel ii  linux-image-4.4.0-51-generic --&gt; new kernel ii  linux-image-4.4.0-53-generic --&gt; new kernel iF  linux-image-4.4.0-57-generic --&gt; new kernel

I suppose you could build a list of all packages that would be installed if you started with an empty apt database and installed everything that deborphan -a currently tells you. Then compare that with what's currently installed.  The difference would be packages that cannot be retrieved automatically with the current list of repositories.  I've no idea where to start with that though.

I did a sudo apt-get remove ruby* and then I saw that some grub packages were being removed too so I went to installed back those packages which log showed to have removed  I set grub to work on my /sda (in general, not any number) when was installing back.  Should all be ok or should I fear for my system and plan installing/reconfiguring more of grub.  And, why did this happpen?

Problem I Faced  I installed something that crashed my Wifi drivers that I compiled earlier. Un-installing the same package doesn't helped. Finally, I re-compiled my wifi drivers and things are good.  My Question But, is there anything like System Restore or System Rollback in Ubuntu/LinuxMint?  Is there anything that can undo an apt-get install package command?

I really like that synapse application launcher, but there seems to be no way of installing it in ubuntu 14.04. Any ideas why? Or does anyone know how I could get it?

I occasionally update my kernel from this web site    I have been always downloading 3 deb files for installing  linux header all, linux image and linux headers. I noticed one more deb file recently for 64 bit kernel called Linux-image-extra.  I would like to know what does kernel file Linux-image-extra do and should I also install it?

In my local repository see below, I have many versions of same packages downloaded and stored in deb package directory. As Ubuntu always prefer to use the highest version, I don't need the earlier versions downloaded and used. (All are in a same folder).   How can I delete the earlier versions of packages from my local deb's folder ? It is not a feasible solution to delete them manually. (You can't examine the versions in thousands of files)   Any ideas?!!  Maybe a script that checks the version of each package keeping the newer version and deletind older ones can solve this issue.  I am seeking for such script or if some software is founded would be great  I have made my local repository following .  *** A local repository is an offline storage of packages already downloaded, so that you don't need to download it again)   Note: I'm not referring to clearing the cache of downloaded packages, which can be done with apt-get clean command.

A few weeks ago I installed a 32 bit .deb file through the 'force architecture' command (on my 64bit notebook), however the procedure was unsuccessful and I used the apt-get purgecommand to uninstall the app. It seems there are some leftovers of the app I uninstalled which has now broken system update. Synaptic recommended a sudo apt-get install -fwhich I did in the terminal with this initial response:  Reading package lists... Done Building dependency tree        Reading state information... Done The following package was automatically installed and is no longer required:   libntfs10 Use 'apt-get autoremove' to remove them. The following packages will be REMOVED:   crossplatformui 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Do you want to continue [Y/n]?   I chose 'Y' then got this response:  (Reading database ... 187616 files and directories currently installed.) Removing crossplatformui ... ztemtvcdromd: no process found dpkg: error processing crossplatformui (--remove):  subprocess installed post-removal script returned error exit status 1 Errors were encountered while processing:  crossplatformui E: Sub-process /usr/bin/dpkg returned an error code (1)   It seems the app I installed crossplatformuiis still on my system and has caused update manager to stop running with a partial upgrade warning. What do I do now?
