Server :: Deleted Keystore - Possible To Completely Reinstall JDK?
Aug 31, 2009
I was having a problem where I had run keytool to generate a key but had entered some bad info. I tried to run it again but it said there was already a key, so I deleted keystore thinking it would regenerate itself. I ran the keytool command again but it says it can't derive the signature algorithm.
Anyway, I've tried to 'sudo apt-get remove sun-java6-jdk' then 'sudo apt-get install sun-java6-jdk' but it doesn't seem to put me back where I was from step 1. 'sudo dpkg-reconfigure' also doesn't seem to fix it. I think if I can completely reinstall jdk then I'll be good, but how?
I just uninstalled, did 'sudo apt-get clean sun-java6-jdk' then installed again. Still get the error:
keytool error: java.lang.Excpetion: Cannot derive signature algorithm
I tried this once but my post disappeared. A thousand pardons if this is a dupe.Through the magic of typos, I managed to delete my ssh binary file. I can receive SSH connections but am unable to SSH into another computer.I located the RPM that looks to be what I'd want -- openssh-4.3p2-41.el5_5.1.i386.rpm -- but it refuses to install. RPM gives me the following conflicting messages:
[root@lightning packages]# rpm -i openssh-4.3p2-41.el5_5.1.i386.rpm package openssh-4.3p2-41.el5_5.1.i386 is already installed and
If I move a file to the trash,I can restore it later.But if I empty the trash,I'll be warned that I cannot recover the files if I proceed.Is this really true or are there Linux applications for recovering files deleted from the trash?Uhm...are the files deleted completely and unrecoverably or are there any traces left behind?
I've installed open suse with no problems however I accidentally put my root folder on an external HD. I want to have my root on a partition of my main drive so I can continue to dual boot windows. Is there a way to move root so I don't have to completely reinstall and set up all my packages and stuff again.I assume to do this I need to use the installation disk again and fix it before boot up but should I partition my main drive first. I'm being intentionally cautious as there is data I'd rather not lose on there.
So in essence, my drive has become a cluster of random partitions, multiple Ubuntu installs, and random windows systems. It's gotten so bad that on my entire 250gb system my main Ubuntu install only gets 40gb of memory. Could anybody give me a step by step guide to do the following:
1. Completely wipe and departition my disc. 2. Install Ubuntu from a backup .tar file 3. Install a 40gb windows 7 partition
After two years worth of trying to get HDMI audio working on, what should be, a MythTV box I am now fed up to the teeth with it. Utterly, completely sick and dissilusioned with Ubuntu & HDMI. Firstly there is no problem with the hardware as I managed to get HDMI audio working using the original install of 9.04. However the sata DVD drive didn't work. So I waited until 10.04 and upgraded after which the DVD drive worked but HDMI audio didn't. So after a couple of months worth of trying everything I could find in forums etc. I gave up and waited for 10.10.
Months later and after installing 10.10 not only does HDMI audio not work but the soundcard details shown in "gnome-volume-control" now only lists a single analogue device whereas running from a 10.10 live CD I get a comprehensive list of available devices including entries SPDIF and HDMI. It's therefore obvious that something I've done in the huge list of things that I've changed has screwed up the audio configuration. And despite having reams of notes I'm in no position to find out exactly what as a) I'm not an expert in Linux audio (nor do I want to be) and b) there have simply been too many changes for me to keep track of.
how can I completely remove *ALL* traces of the current audio system and reinstall *EVERYTHING* related to audio using the latest versions ? I want to completely obliterate the current audio installation (including all configuration files, kernel headers, drivers, alsa, the wretched pulse audio etc. etc.) and start from scratch. I have already been through every sinlge HDMI related forum post and have tried everything so please don't suggest "make sure HDMI audio is unmuted in alsa-mixer" etc. as I've been there, tried that and am bored with it all. I want to completely nuke the audio system from orbit and start again. At this point I should say that I've already tried the following which didn't make any difference:
And to prove that the device is there here's the output from "aplay":
aplay -l **** List of PLAYBACK Hardware Devices **** I: caps.c: Limited capabilities successfully to CAP_SYS_NICE. I: caps.c: Dropping root privileges.
[code]....
Or should I just give up and install Windows media centre ? Having preformed a trial installation of Windows on a seperate disc everything "just works" with perfect HDMI audio, perfect picture, DVB card working perfectly, DVDs Playing etc. etc.
I've forgot to add/make clear, as I have said this is a single OS system, if there is a less complicated fix that will leave me without grub (but with a bootable system) that would be fine. Something like Code: fdisk /MBR but I understand that command is only for DOS, correct?
I've managed to delete/screw up my installation of GRUB. My hardware RAID controller had gone on the fritz and I was getting an operating system not found message during boot. Turns out I needed to reload the firmware for the card. I now believe the card is working fine however in trying to troubleshoot the problem (which I initially thought might have been related to GRUB) I have managed to hose GRUB, and I now see Code: Loading GRUB..
Error 15 at startup. I am running Ubuntu 8.0.4 LTS. I have been using an 8.10 desktop live cd for troubleshooting. Grub-install does not work when using the live cd. I have tried to follow directions given on this page: [URL]. However if I chroot to where my OS partition is mounted on the live cd: Code: chroot /media/disk it does not recognize the grub command.
If I simply try: Code: sudo grub find /boot/grub/stage1 it does not find them. If I try:
Code: sudo grub root (hd0,0) setup (hd0) it checks for stage1 and does not find it. (This may be related to the fact that I am not chroot'ed to the correct OS partition when trying to run these commands, since, as I have mentioned before, I can't get the grub command to run after I chroot to my OS partition.)
When I initially started fooling around with grub I did not even have a boot partition, so I am not even sure that I had GRUB installed in the first place (this was simply a clean install of 8.0.4, not a dual boot system) but since then I must have screwed up the MBR by trying to reinstall/fix what I thought was a broken GRUB. I could not find the GRUB files on my computer, so I have downloaded GNU Grub 0.97 and unzipped it, and moved the entire contents into a /boot folder which I created, so I now have the proper /boot/grub/stage1 directory. (However I never ran any installation after downloading grub, I simply moved the files, perhaps this is the issue).
I soon found out that Suse 11.1 would no longer boot from boot.ini (using bootpart) because the boot process now brings up PCLOS (in /dev/sda6) rather than Suse 11.1 sitting in /dev/sda5. No problem, I thought, I'll boot from the Suse install DVD, use repair, and away I go. Wrong. After grinding, it started mentioning about generating something for sda13, which is my last partition. NTFS! So I bailed before it got too far. I even tried "rescue" option on the DVD, command prompt, and grub commands to reinstall via "setup.
Then I tried to use Super Grub Disk (.97xx) to reinstall the PBR, stage 1 and stage 2 loaders. Didn't change a thing. So then I used Grub4DOS and got into my Suse 11.1 installation using this in its menu.lst: title openSUSE 11.1 - 2.6.27.45-0.1
[Code]...
Worked fine, and is now my (only) method of booting to 11.1. So obviously it's bypassing stage 1 and 2 files, using it's native Grub4DOS code. But then I tried Yast-Bootloader to reinstall Grub's files. No difference. Then I used the advanced part to "write bootloader code to disk" No difference. Even tried "propose a new boot scheme" (or whatnot) no difference. After looking at all this, I've come to the conclusion that the PBR code in sda5 is scraunched, and/or stage 1 code (although it's still the original date), or stage 2 (which definitely had a new timestamp of when I committed the fatal error by executing PCLOS's "install.sh".
So my question is this: How do I do a good COMPLETE re-install of Suse's version of the grub files? Because, for sure, grub commands like "setup --stage2=/boot/grub/stage2 (hd0,5), and variations thereof, certainly aren't doing it? My reasoning is that I should make sure that all the boot files get restored/confirmed as "originally installed by Suse".
I just install Ubuntu on a new computer I got, and set up LAMP. I started poking around in MySQL (more than I should have) and managed to break it. I've been trying to fix it, but I can't. I've done apt-get --purge mysql-client, but when I reinstall it it's the same thing. How can I reinstall MySQL (and PHPmyadmin) from a completely clean slate? (There's no important data on there)
I use slackware 13.1-current on desktop with 4gb ram, nvidia geforce 210, and AMD cpu. I have problem with my X starting using 40-50 MB of RAM and after some hours suddenly rises up to 400-500 MB. I have tried KDE ( with and without desktop effects ), LXDE, 3 different nvidia drivers ( the one made from the slackbuilds ) but no luck. I decided at last to use the default slackware's driver. I uninstalled the nvidia driver and do startx, but it says code...
I have no idea about GPU and drivers, it was a mistake to install a driver for my nvidia just to have desktop effects. I just want to bring the things back as at the beginning of the systems installation and the default drivers. Do you have any idea how to do it?
I deleted Ubuntu off of my laptop, because I was having some issues with it (I had lost some of my icons in Software Center, couldn't access my Yahoo Mail etc..). I deleted it using this method. I then went into my Windows Vista OS, and accessed Disk management via Control Panel.The partition Linux was previously on was Unallocated, and I had a D partition which was Windows recovery. I then shrunk my C (main Windows) partition down. I deleted the D partition.So now I have the C partition, and a large unallocated partition. I was planning on installing Ubuntu from CD onto this unallocated partition. I am using the same CD I had previously used to install Ubuntu. My roommate was also using the same CD today to install Ubuntu on his computer. I know the CD works.
So when I inserted the Ubuntu CD it loaded the first couple of screens. It got to the purple screen where the install text would normally have appeared and then continues to load.... but the "do you want to install? etc..." text did not come up. It then loaded to a black screen, loaded back to the purple screen, reads the disc, keeps loading... and loading... and nothing ever comes of it.I tried again, this time when the first purple screen comes up, I hit enter. I get the language select. I then get the options. I click install Ubuntu. it then starts loading... and loading... black screen, purple screen, black screen with text... but nothing comes of it.My windows is working fine. I don't know why it won't install
I had to delete my swap partition in order to reinstall win XP, but now I need to reinstall it. I run Ubuntu 10.04 and read that there is a command $ sudo mkswap /dev/sda1. I have about 19 GB of free unpartitioned space left on the hardrive that I want to make into a swap partition. I'm not sure whether I should use sda1 or if the book uses it as an example and if I use it it could wipe away my existing partition with ubuntu installed on it.
My /boot folder is deleted by an unwanted mistake. I'm using F14 x64. I have updated my OS and I also installed more than 2 GB packages and It is very difficult for me to re install Fedora. Is there any way to fix this problem with out re installing Fedora?
My gateway netbook was dual booted with windows 7 and ubuntu netwbook.,I was attempting free up some space on my netbook and decided that the ubuntu partition was expendable.I deleted it and sufficient to say I now can't boot boot up, I just get an error message, can't remember exactly what it is.I am getting a new computer and would kind of like to be able to recover the files on the computer.I have a USB netbook boot drive and am wondering how I would be able to install ubuntu without loosing the files.I have the usb key plugged in am now at the partition stage of the installation.
i installed the new ubuntu on my system as a side by side installation, i've been using it for about 2 weeks now. ported over or found linux equivalents of any applications and games i use onto my ubuntu partition, and now i've decided i want to have ubuntu use the entire drive and just delete windows! The problem is, i'm not sure if i can do that I shrank my windows partition half a gig and booted lupu (the ubuntu partitioner wasn't even showing this half a gig of free space) to see if i could just extend my linux partition (in the case that this did work, i was just planning on deleting my windows partition and just extending my linux to the full size of my drive). I really want to avoid a full reformat of the drive because i have customized my ubuntu a decent bit and i don't want to have to redo all of that (not to mention the data, but i could always back that up on an external hdd). Here is a screenie of gparted: i don't really know too much about partitioning. so is there any way to remove windows and give linux the rest of the drive without having to completely reinstall ubuntu?
I would like to completely erase my hard drive and install Ubuntu 10.04 on again fresh. I think some files have become corrupted from a power cut that I had last night whilst the laptop was plugged in (and turned on).
I'm not bothered about completely wiping the hard drive since there are no important files on it (at most there are just a lot of packages I downloaded from the repro...) I don't have any Windows installations either - it's just a simple; wipe the hard drive and reinstall all over again case
How do I ensure that my home partition does not get deleted the next time I reinstall Ubuntu, as I can see there is a choice between formatting the whole drive and manually partition it, but if I reinstall won't I delete the home partition as well?
I got a system crippling virus on my windows installation. My recovery disks gave me the same problem. So I installed Win 7 enterprise using a disk my dad got from his work. The installation went smoothly. When I started my computer after it went straight to Win 7 without the GRUB bootloader (not the case with restore disks). Could somebody please help me with this issue because I cant stand using Windows for anything other than games much longer.
This is partly a note to myself for the future and a guide to anyone who experiences similar issues.
So, I had to reinstall Windows XP since my previous installation gave me a blue screen error due to reasons unfathomable. Naturally, this deleted the GNU Grub and I could not login to my Fedora.
I read that apparently booting from a DVD installation offers an option to enter the rescue mode. I did not have a DVD, I only had the LiveCD so I had to figure out a way to reinstall Grub from the LiveCD. The following method seemed to do the trick.
Run the LiveCD and open Terminal.
1. Find the partition where the Grub Stage1 is code...
I've been trying to set up a mail server and I'm a bit lost on how to get it working. I'm running a centos server with sendmail and dovecot. All the guides I've read don't seem to help at all. All I want to do is set it up so that I can send and recieve email. That's all I want
Is it possible to block a server completely from any connectivity to my Ubuntu system so that not even Google Search will detect files from that server?[URL]This is because of a nightmare issue I have been having with the Firefox Addon "DownThemAll!" which, I won't go further into.
I recently screw up mysql server privileges and now im having problem accessing tables/databases. so i wanna uninstall mysql server completely and reinstall it. i installed it previously through yum install mysql mysql-server. how should i do it?
I'm wondering why everytime I install "recomended" updates, my KDE or X server crashes completely! is there any guide or advice you can give me to succesfully update only the packages that are really needed?
After a ssh remote login and trying to start my vncserver, I cant login any more on my ubuntu 10.04. During this session I have executed some command with "xterm" and "display:0" and I suspect that is causing my problem now: At startup I have an error message in a window, with following message "running in low-graphics mode" and other phrase with something about my keyboard. Then I have some choises, like Start in low graphics or normal mode, and some more, but nothing seems to works and all I get is a 100% black screen with cursor, no ubuntu, and I must reboot PC in XP to come here...
I recently installed opensuse 11.2 on my laptop which also had windows vista and windows 7, i created a new partition and the installation went smoothly, after i went to boot back into windows 7 i got a blue screen of death, strangely vista boots perfectly.I could just reinstall windows 7 but its a pain to reinstall all my programs and such
So I was messing around trying to uninstall Nibbles and reinstall since I have an issue starting that game and something happened and removed the submenu under Games called "Logic", which had another whole list of games.
Is it possible to reinstall the games package or reinstall the update?I'm thinking more of the lines of a system restore or something so back 2 days from today.
