I'm taking a class this semester on Linux and a Fedora 13 DVD came with the book. Just now I've installed Fedora at home and started the updates. I saw a PAE entry in the updates so I went to the Terminal and typed uname -r and I see that the Fedora 13 DVD installed a PAE kernel on my machine that has only 1 GB of RAM.
Why did it do that?
Can I swap out the PAE kernel for a non-PAE kernel? (edit- I'm a Linux noob so I don't know)
Does it really matter?
After the updates I was going to try to install the proprietary Nvidia driver.
Whenever I boot up Fedora 15 on Virtual Box, I get the message " gnome 3 could not load " and I installed all the packages needed to install Guest Additions, but even when I mounted the file, the ONLY file I could find online that was VMBoxGuestAdditions.iso or something like that, I mounted it, I tried installing, but nope, it gives me an error message that it can't. I have the latest version of VirtualBox and I've been on several forums and looked at many places but I can't fix it. I also have a problem where when I boot it up it says " the system is optimized to support 32 bit but it is currently 64 bit go here and click this to fix it " or something like that. and I can't figure out how to fix it in Virtual Box.
when ever i try to install updates i get shown an error & the updates stop the error i get says "librpmio.so.0 is needed by package abrt-1.0.3-1.fc12.i686 (updates) librpm.so.0 is needed by package abrt-1.0.3-1.fc12.i686 (updates)"
Sometimes you get more than you ask for and in this case, I did: I had no idea (had the computer for a few years now) that I was running a dual core 64 bit machine. The silly thing is that I have 32bit Fedora 11 on it, 32 bit versions of all my installed software...etc., etc. Am I able at this point to salvage anything or is it best to just back up the home directory and then do a reinstall?
I tried to update to Ubuntu 11.04 from 10.10, and I got a strange error like "Unable to calculate changes, package ubuntu-desktop is needed but not going to be installed". Then the sistem claimed to return back to the previous state, but now ALL the package are marked as "upgradable", and the Software Updater is suggesting me to do a "partial upgrade". What happened? How I can get back with a coherent system? I don't installed the xubuntu-desktop, BTW.
Today I got update notification. I type in terminal yum update, and get this error: Quote: Error: Missing Dependency: libnetfilter_conntrack.so.1()(64bit) is needed by package iptstate-2.2.1-5.fc11.x86_64 (installed) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest
I removed iptstate.x86_64, again run yum update, and than, ibnetfilter_conntrack got installed. I tried to install iptstate.x86_64 again, but i get Quote:
Trying to install yum-installonlyn, yumex reports a dependency error because libgif.so.4 is needed. However, that library is in /usr/lib and I also have copied it to /lib - with no success. Could anybody tell me which piece of information I am failing to give yum?
I'm new to fedora, but had installed it once before on machines for my class. I am now trying to install fedora on my PC at home, but every time I run the disk and chose install from the main screen all I get is a bunch of text and then it says "Fixing recursive fault but reboot is needed"
I have just installed from the Live Cd (Fedora 13). So far so good except that I have just installed the updates (which has taken some time) .
The updater screen shows a full progress bar and next to the progress bar is this text " checking for libraries currently in use" this has been at least one hour showing the same thing, it hasn't changed (PC is still running OK). Does this mean I can safely quit and the updates will be OK or should I keep waiting for a reboot screen or updates success message ? Is this normal, if so how long does it usually take to complete?
I recently got Fedora 11, I've heard it's not the best distro to learn Linux with, but I'm liking it so far, and having a good time
I've gotten the OS up, network works, and I'm using it now. So I'm trying to get a few plugins and applications and I'm having some trouble. Main two I'm working on right now are Adobe Flash Player and Wine. I downloaded and installed Adobe Flash Player, but it didn't register that I had it on Firefox.
I took my laptop to best buy, and after about a half an hour, they said I was missing these libraries/plugins:
I am a Fedora neophyte, upgrading a web server from Fedoras core 5 to Fedora 13. I finally got Apache and perl up and running, but my Perl scripts don't run because of the lack of Perl libraries.I have been able to use yum install thus far to get what I need which is a terrific tool when it works. I note there is a specific tool named 'cpan', and of course one can download libraries directly from the cpan.org website.Unfortunately, I have tried to download perl libaries from yum the cpan library from yum, and in each case I get:
And it has tried maybe 20 mirrors, alway with the same result. What is the best way you experienced Fedora types have found to download and install perl libraries (like LWP for starters)?
I am trying to run algodoo from terminal after I install it, but it doesn't run. It gives this error. I have been having troubles with permissions in the /usr folder recently, so I think that is what might have caused this. Please read through it thoroughly, as algodoo is actually located in the /opt folder.
Code: jon-Tuxbox:~$ sudo '/opt/Algodoo/algodoo/algodoo' There are missing dependencies. Please make sure that all the required libraries are installed. Missing: libcxcore.so.2.1 => not found libcv.so.2.1 => not found libhighgui.so.2.1 => not found jon-Tuxbox:~$
i have a dell inspiron laptop lap top with windows7 os.my hardisk is 320gb capacity.now i want to install fedora as my secondary os. I tried fedora12 but instaltion terminated abnormally with the message safe reboot needed recievied signal 3. i have 20 gb unallocated space in my disk.
I havent used Linux in a long time. I dug up an old copy of Suse (version8.2), and installed it on an old 599MHZ PC. Ive been trying to update the various libraries to be able to get a updated version of Firefox installed. Is there any chance that this can work? I need to know if Im wasting my time and should just put winxp on this PC. Also, I cant get any repositories working. I assume the default ones I have on the Suse installation are bad and the ones for the later versions will not work.
I installed a software that is used for modeling purpose. After installation, it showed me the following error.
error while loading shared libraries: libXm.so.3
I hope i need to install some libraries. While i searched in google, i found some postings telling i should intall libmotif3 and some postings telling that openmotif should be installed. I dnt know what to do now as i dnt find both these libraries when i try to install with yum.
Someone kindly write me how to get this libXm.so.3 installed in fedora10.
According to various sources, this should mean that applications have priority over file chaches, and swap should only be used when the applications themselves need more memory than is physically available. So I naively took the value free provides in the '-/+ buffers/cache' line as 'free' as the amount of memory to be available on the server. Unfortunately this is not even close to true: On a server with 20GB RAM, memory utilization by this measure never reached 50%, yet the system swaps.
I then figured out that I could use 'sync; echo 3 > /proc/sys/vm/drop_caches' to drop cached stuff. I was very surprised to still have 12.5 GB cached data after doing that. I am figuring that it's those 12.5 GB which force the system to start swapping. I also tried to use /proc/meminfo to figure out how that cached memory is used (by comparing its content before and after dropping caches). However, I don't see the correlation between the numbers provided there and what part of the cache can be dropped.
The closest match seems to be the 'Mapped' line, which was 10GB. I am pretty sure that being mmapped keeps the kernel from dropping cache. However, the value is 2.5 GB less than the cache which can't be dropped. So it is not the whole answer. What I am looking for is some way to determine how much memory the kernel could provide by dropping stuff if he needs to because of memory pressure. Is there maybe a way to simulate drop_caches without actually doing so?
The amount of potentially available memory does not have to be scientifically correct, but the number should at least be always in the right ballpark, which right now, it ain't... The point here is that it's a productive system. Sy doing stuff like dropping caches or filling memory until the system starts to swap is not a permanent solution to figure out the value. By the way, it turned out that postgres was the culprit in this concrete case, stopping it made dropping all caches possible, but that does not answer the general question of how to estimate available memory...
1. Is my assumption correct that I can subtract 'Mapped' from the freeable cache memory completely?
2. Where could the other 2.5 GB be used?
3. Is there a way to get a better guess of how much memory the system can free if necessary, before swap has to be used?
I am trying to install kcachegrind and during the ./configure phase I got the following error: Checking for Qt... configure: error: Qt (>= Qt 3.0) (headers and libraries) not found. Please check your installation!
Now I guess I have QT installed and I tried to do the following: ./configure --with-qt-includes=/usr/lib64/qt4/include but that did not work either.. actually checking further I found that the folder include is missing in usr/lib64/qt4/ !!!!
I installed MATLAB R2009a in my laptop (Fedora 14 x86-64), the installation was succesful but when I run MATLAB (in a console), appears a message: error while loading shared libraries: libut.so: cannot enable executable stack as shared object requires: Permission denied
I find a "solution", execute in a terminal: execstack -c libut.so
I used several times with differents libraries that I needed, but I run MATLAB in a terminal, MATLAB starts in a terminal, only a prompt ">>" and nothing.
Trying to launch Second Life gives the following error message:
You are running the Second Life Viewer on a x86_64 platform. The most common problems when launching the Viewer (particularly 'bin/do-not-directly-run-secondlife-bin: not found' and 'error while loading shared libraries') may be solved by installing your Linux
This problem was easily found using search with solutions for Fedora 11.
The following information has been found for adding the 32 bit support to Fedora 11 but it does not work in Fedora 12.
The file created in the instructions below is a list of the 32 bit libraries. It is then called as input to yum to simply install them.
"Add the Libraries Next, add the 32-bit libraries by copying the following list, and pasting it into a text file. Save it as �Fedora-ia32.txt�."
Another post says that was all unnecessary as the following commands would do the same thing.
Could have simply been achieved by calling:$ yum install SDL.i586...(Or by selecting SDL.i586 in add/remove programs.)
The problem I have with Fedora 12 are neither of these will install anything in Fedora 12. Looking at add/remove programs does not yield anthing that looks like it is 32 bit support when searching with the argument "SDL".
Does anyone know how to install 32 bit support into Fedora 12 64 bit version ? I like the simple yum expression rather than long lists like the first example uses, but I'll try anything if it works.
A side question to this entire experiment is what chance would you give to Second Life being able to be run remotely using VNC? I would think if it runes on the Linux machine, using a remote terminal would have little impact. Using VNC isn't the usual way this will be run, I just wonder if it would work at all.
Installed Truecrypt onto openSUSE 11.3 (KDE) and noticed that Truecrypt needed to be started as root.Modified visudo using YAST asusername ALL = NOPASSWD: /usr/bin/truecryptHowever, when copying files from my backup drive into the Truecrypt partition, there is an access problem (couldn't remember actual error message)In Konsole , updated visudo to username ALL = (ALL) NOPASSWD: /usr/bin/truecrypt Copying is allowed and working fine.Question:1. What is the difference between the above two visudo setting?2. How to updated visudo to the second setting in YAST?3. How to change the editor for visudo in konsole using nano instead of vi?
Running solo Ubuntu 9.1 on current AMD-965/MSI_gd70 desktop. Recently I upgraded hardware ( new ram/2nd hdd/temp-probe ) on this kit. All function appeared nominal and all hardware appeared in BIOS. After adding a new line in /etc/fstab to conjure-up my new 650-G sata I rebooted. I can access **nothing** on my system .except FireFox and THAT because I have a FF_icon on my desktop. The system boots, and std Gnome GUI appears, but excepting *LOGIN* none of the tool-bars have any function whatsoever.I cannot reach the command-line.
How does one access a Virtual Box installed Fedora system? I'd like to be able to ssh into this system (locally) but I've no idea how to do this. There is an ip address of 10.0.2.15. Ping doesn't work (ping 10.0.2.15). Should I just go ahead and assign a 192. address to this box before I go any further? It would seem that at this point the system isn't actually a part of my local network and I don't imagine it would be unless it has a 192 address.
