When I try to install updates from the update manager it says:  Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-3.0.0-13-generic_3.0.0-13.22_i386.deb   Size mismatch   I have tried several times and through terminal too but the size mismatch repeats itself there too. What is this size mismatch error?  I also tried sudo apt-get update and sudo apt-get upgrade, but the error comes again.

I have tried searching for this but there seems to be no command that can output a list of packages (ideally in Ubuntu) that I have installed, not including any dependencies.

The old-releases.ubuntu.com mirror hosts the repositories for EOL Ubuntu releases. The  currently lists up to 11.10 (or 12.04.3 if you count point upgrades), but the  lists up to 13.04. Why the discrepancy? When will the main page be updated? When will the newest EOL release (13.10) be shifted here?

I've tried to deal with this for days now with no luck. In this forum and also in other ones I can see a lot of discussion about this but none of the solutions have worked for me.  My current situation is that I've got some GBs "missing" that I can't free or find anywhere. I guess this is some kind of problem like memory leaks that only get fixed when rebooting, but I just would like to ask if someone has a better idea because there are currently a few customers on that server.  Here are some of the commands I've seen in other threads and my particular outputs:  df -h  Filesystem            Size  Used Avail Use% Mounted on /dev/sda1              19G   16G  1.8G  90% / tmpfs                 384M     0  384M   0% /lib/init/rw udev                   10M  1.2M  8.9M  12% /dev tmpfs                 384M     0  384M   0% /dev/shm   du -Pshx /* 2>/dev/null  4.8M    /bin 27M /boot 0   /cdrom 1.2M    /dev 8.8M    /emul 504M    /etc 4.0K    /grubconf 88K /home 60K /images 0   /initrd.img 147M    /lib 0   /lib32 0   /lib64 16K /lost+found 12K /media 4.0K    /mnt 4.4M    /opt 777M    /proc 57M /root 4.7M    /sbin 4.0K    /selinux 4.0K    /srv 0   /sys 4.0K    /tmp 332M    /usr 471M    /var 0   /vmlinuz   lsof +L1  (no output)   lsof | grep -i delete  (no output)   find / -size +50000 -exec ls -lah {} +;  -r-------- 1 root    root 777M 2015-07-21 06:19 /proc/kcore -rw------- 1 root    root  64M 2015-07-09 03:31 /sys/devices/pci0000:00/0000:00:06.0/0000:01:04.0/resource0 -rw-r----- 1 root    adm   49M 2015-07-21 06:19 /var/log/auth.log -rw-r----- 1 root    adm  174M 2015-07-19 06:25 /var/log/auth.log.1 -rw-rw---- 1 control mail 100M 2015-07-21 06:00 /var/mail/control   If you make the maths from du, for example, you get a few GBs, but nothing close to 16GB.  / is ext3.

So I've been messing with thing that probably shouldn't be messed with trying to learn my way around Linux, and I seem to have messed something up. I'm getting a lot of error messages, reduced speed, and crashes, so I'm going to do a clean install.   However, I an using mobile broadband and don't exactly want to use all of it up again re-downloading updates.  Is there any way I can save all the packages installed now with their updates to an external hard drive?

I am in the process of cleaning up my system. And I see a lot of space occupied by this folder /var/cache/apt/archives (1.5GB). Is it absolutely necessary to keep all these archives?

I'm trying to update from ubuntu 12.10 lately but I keep getting the "Failed to fetch" error.

This is probably actually a more general question which is : how do I see which packages will be installed when I install a metapackage? In this specific instance I have mostly only found vague descriptions like      Installing this package will pull in support for MP3 playback and decoding, support for various other audio formats (GStreamer plugins), Microsoft fonts, Java runtime environment, Flash plugin, LAME (to create compressed audio files), and DVD playback.    from    apt-get install ubuntu-restricted-extras tells me that I am installing one package: ubuntu-restricted-extras.  Especially in this case, I'd like to know what I'm putting on my computer and what agreements I am tacitly agreeing to by doing so. I'd also sort of like to know what the difference between the various *ubuntu-restricted-extras packages are.

Suddenly my Ubuntu stopped playing video. When I open a video, the player suggests that I install  gstreamer1.0-libav. However, it fails to install.

I tried installing VLC Player yesterday, and I got the Requires installation of untrusted packages error.  I searched for hours for a solution to this problem, and finally came upon a suggestion that said to change servers for downloading updates from.  I did this, and it gave me a 404 error when I clicked on "Check" in the Update Manager.  I tried switching my server back to the main one (and after that, several other ones), but I am now still getting a 404 error:   And the other error I get when downloading or updating:   Edit: Output of cat /etc/apt/sources.list:  deb-src http://us.archive.ubuntu.com/ubuntu/ precise main restricted #Added by software-properties  # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://us.archive.ubuntu.com/ubuntu/ precise main restricted multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ precise multiverse universe #Added by software-properties  ## Major bug fix updates produced after the final release of the ## distribution. deb http://us.archive.ubuntu.com/ubuntu/ precise-updates main restricted multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ precise-updates restricted main multiverse universe #Added by software-properties  ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.

given a package name, I want  to find how much space would be freed up if the package, and its dependencies, were deleted.  As dependencies might be shared between packages, maybe the right way to put it is: How much space does a package take, including all dependencies that are only beeing used by this package  I would prefer CLI solutions, because I would use them in scripts

Google has  so on a 32bit Debian machine it's not possible anymore to update the APT repository:  W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release  Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)   Also has the .deb file removed from Google servers as it seems.  Is there any alternative .deb download of the last release (46?) available somewhere?  Reason: For an automated Debian build system (debootstrap-based) I urgently need a way to install Google Chrome 32bit v46 (or similar). Switching to another browser (including Chromium) is not a quick enough option for me at the moment..

I use youtube-dl to download videos for watching later offline. Usually, it works fine. However, due to frequent changes on the video sites, it sometimes requires a quick update. It wasn't a problem before on 13.04 but after upgrading to 13.10, I get  # youtube-dl -U It looks like you installed youtube-dl with a package manager, pip, setup.py or a tarball. Please use that to update.   I tried updating it via apt-get but there is no new package. So the app's update mechanism has been disabled and the maintainers aren't keeping up, what is the solution? How do I update it?  And why was it changed at all? It was updating a package manager version just fine in raring.   I'm already running into compatibility problems.   $ youtube-dl "http://vimeo.com/55784152" [vimeo] 55784152: Downloading webpage [vimeo] 55784152: Extracting information ERROR: Unable to extract info section; please report this issue on https://yt-dl.org/bug .
