Ubuntu 13.04 apt-get error : Too many levels of symbolic links

# tail -1 /etc/lsb-release ;uname -ri DISTRIB_DESCRIPTION="Ubuntu 13.04" 3.8.0-33-generic x86_64

When issuing apt-get upgrade, I saw the following errors.

I am not sure what is the trigger on this issue, because other Ubuntu13.04 boxes can do apt-get upgrade without problems.

# apt-get upgrade Reading package lists... Done Building dependency tree Reading state information...

/usr/lib/nx/nxserver is NoMachine FreeNX which is similar to VNC, Remote Desktop.

/usr/lib/nx/nxserver -> /usr/bin/nxserver -> /etc/alternatives/nxserver -> /usr/lib/nx/nxserver..

round and round ..

how about remove this file?

# rm /etc/alternatives/nxserver rm: remove symbolic link ‘/etc/alternatives/nxserver’? y

I was able to fix this, however I am not sure this way is appropriate or not.

Windows 7 : Windows Update : error = 0xC8000247 ( HP pavilion desktop )

Windows update service has not worked after replacing an old HDD with a new one due to HDD failure.I have installed Windows 7 Pro 32bit into the new HDD using the recovery media shipped with HP. ( I replaced 320GB HDD with 500GB HDD )

Windows update service is running , however I can’t apply patches.



The following is the WindowsUpdate.log when issuing updates with CLI

Do the update with CLI

C:\Windows\system32>wuauclt.exe /detectnow

When googling this issue , I've found that this might be corrected by installing "Intel Rapid Storage Technology Driver".
In my case , I could solve this issue after installing "Intel Rapid Storage Technology Driver" which I downloaded from HP site.
You will find the driver for HP desktop by just googling “HP pavilion model name driver”.

After installing the driver.

FreeNX error : Error is 112 'Address already in use'

When I try to connect to Ubuntu from FreeNX client ( Windows ) , I have faced the following error.

error message on NX client

Info: Connection with remote proxy completed. Error: Call to bind failed for font TCP port 11001. Error is 112 'Address already in use'.

# apt-cache policy nxserver nxserver:  Installed: 3.5.0-11  Candidate: 3.5.0-11  Version table: *** 3.5.0-11 0        100 /var/lib/dpkg/status # apt-cache policy nxnode nxnode:  Installed: 3.5.0-9  Candidate: 3.5.0-9  Version table: *** 3.5.0-9 0        100 /var/lib/dpkg/status

I try to connect to two different Linux boxes from the same NX client at a time.
I can establish the first NX session , however I can’t establish the second NX session...

NX client (windows ) --- NX server ( Ubuntu 12.04 )  <- can establish :D
                    --- NX server ( Linux Mint 13 )  <- can’t establish :(

NX client seems to use the same TCP port number for both NX session.
To solve this , edit node.cfg on the NX server to avoid the NX client using same TCP port.

- on the Ubuntu 12.04 box ( NX server )

# egrep -i ^display /usr/NX/etc/node.cfg DISPLAY_BASE=1000 DISPLAY_BASE + 3000

restart NX server

# /etc/init.d/nxserver restart

- on the Linux Mint 13 box ( NX server )

# egrep -i ^display /usr/NX/etc/node.cfg DISPLAY_BASE=2000 DISPLAY_BASE + 4000

restart NX server

# /etc/init.d/nxserver restart

After editing node.cfg , I can connect to the two NX server boxes on the same NX client at a time.

Fedora 16 64bit : yum : Error: failure: repodata/filelists.xml.gz from google-chrome: [Errno 256] No more mirrors to try

[root@fc16 ~]# cat /etc/redhat-release Fedora release 16 (Verne) [root@fc16 ~]# uname -ri 3.3.0-4.fc16.x86_64 x86_64

When issuing “yum update” , I see the following error.

[root@fc16 ~]# LANG=C yum update -y http://dl.google.com/linux/chrome/rpm/stable/x86_64/repodata/filelists.xml.gz: [Errno 12] Timeout on http://dl.google.com/linux/chrome/rpm/stable/x86_64/repodata/filelists.xml.gz: (28, '') Trying other mirror. Error: failure: repodata/filelists.xml.gz from google-chrome: [Errno 256] No more mirrors to try.

It seems that this is yum issue.
I have installed Fedora 16 64bit on my desktop and Fedora 16 32bit on my laptop.
This error occurs on Fedora 16 64bit ver.

[root@fc16 ~]# LANG=C yum --version 3.4.3  Installed: rpm-4.9.1.2-6.fc16.x86_64 at 2012-03-26 15:43  Built    : Fedora Project at 2012-03-07 11:29  Committed: Panu Matilainen <pmatilai@redhat.com> at 2012-03-07  Installed: yum-3.4.3-7.fc16.noarch at 2012-02-21 14:08  Built    : Fedora Project at 2011-12-09 19:06  Committed: J??n ONDREJ (SAL) <ondrejj(at)salstar.sk> at 2011-12-09

To solve this :

issue “yum clean metadata”

[root@fc16 ~]# yum clean metadata 読み込んだプラグイン:langpacks, presto, refresh-packagekit 14 metadata files removed 4 sqlite files removed 0 metadata files removed

then issue “yum update” again.

[root@fc16 ~]# yum update -y <snip>  vlgothic-fonts-common.noarch 0:20120312-1.fc16                                  vlgothic-p-fonts.noarch 0:20120312-1.fc16                                       yum.noarch 0:3.4.3-23.fc16                                                     完了しました! [root@fc16 ~]# echo $? 0 [root@fc16 ~]#

If you still see an error , please try the below.

# yum celan all # yum clean metadata # yum update -y

small tips : Ubuntu : apt-get error : open (11: Resource temporarily unavailable)

# apt-get update E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/

Just remove /var/lib/apt/lists/lock file.

# rm /var/lib/apt/lists/lock # rm: remove regular empty file `/var/lib/apt/lists/lock'? y

After removing the lock file , you will perform apt-get w/o the error.

# apt-get update Ign http://jp.archive.ubuntu.com oneiric InRelease Ign http://jp.archive.ubuntu.com oneiric-updates InRelease

In my case , this occurred after the network connectivity had been lost and I had aborted the apt-get command.
