I am upgrading my WSL2 instance from Debian 10 to Ubuntu 20.04 LTS, because I need some newer packages.
How do I copy files and directories from Debian to Ubuntu, preserving the permissions and owner? (uid and gid are the same in the two Linuxes.)
Copying to windows first changes the permissions and owner of files.
explorer.exe also changes permissions and owner.
Preferably, I'd also like to avoid having to create a shared disk image file that I could mount from Debian and Ubuntu in turn.
I'd like something simpler, like accessing the second WSL instance directly from the first, e.g.,
$ cp -a <Debian>/myfiles/ <Ubuntu>/myfiles
Is this possible?
See also my similar question: How to access \wsl$\othercontainer\some\file from within a WSL container? where the short answer is:
sudo mkdir /mnt/othercontainer
sudo mount -t drvfs '\\wsl$\othercontainer' /mnt/othercontainer
ls -l /mnt/othercontainer/some/file
NOTE: It looks like symbolic links aren't supported.
Use tar. It will preserve all the file metadata.
In <Debian>, create myfiles.tar.gz:
tar zcvf myfiles.tar.gz myfiles
Copy myfiles.tar.gz to your windows drive e.g. with explorer.exe or with /mnt/c, and then copy myfiles.tar.gz to <Ubuntu>. In <Ubuntu>, untar it:
tar zxvf myfiles.tar.gz myfiles
I was trying to run TensorBoard example : mnist_with_summaries.py and when I tried to open an instance of TensorBoard I got this :
command:
'tensorboard --logdir=/output --host localhost --port=6006'
output:
'TensorBoard 1.5.1 at http://localhost:6006 (Press CTRL+C to quit)
W0219 15:12:02.944875 Thread-1 application.py:273] path /[[_dataImageSrc]] not found, sending 404'
When I try to open http://localhost:6006, my browser crash.
I am on Ubuntu 16.04, with tensorflow GPU and the 1.5.1 version
I found a solution for this:
DO NOT USE "" or '' in the logdir path. Say, if you cd into the parent folder of log files (training folder is my log files parent folder), use "tensorboard --logdir=training" instead of "tensorboard --logdir='training'". This method works for my environment.
This is because you entered the wrong directory. For example, the file is in E:/path/to/log/events.out.tfevents.1526472789.DESKTOP-CUF1KNI
you should cd to the E:/path/to/"directory,ues "tensorboard --logdir=log
You may cd the E:/path/to/log directory, this will cause the error.
i used tensorflow ver0.12.0. i wanna use ver 0.10 so i run pip install tensorflow
then when i use tensorflow ,

Thank you for your help.
enviroment
ubuntu14.04
python2.7
download libcudnn.so.6 in https://developer.nvidia.com/cudnn.
put it to /usr/local/cuda/lib64/ folder
and use next commond
sudo chmod u=rwx,g=rx,o=rx libcudnn.so.6.5.18
sudo ln -s libcudnn.so.6.5.18 libcudnn.so.6
sudo ln -s libcudnn.so.6 libcudnn.so
Change directory to

Most (all?) information online is outdated since ECW (Hexagon Geospatial/Intergraph) has recently released new versions with breaking changes (5.0, 5.1 and 5.2).
Most instructions result in errors like:
checking for libNCSEcw.so or libecwj2... configure: error: not found in /usr/local/lib or /usr/local/bin
This works for GDAL 1.11.2, but it should work back to 1.10.0.
Download the latest version of the ECW library from here (currently 5.5):
https://download.hexagongeospatial.com
Instructions for v5.2.1, but should be similar for the latest version:
$ unzip erdas-ecwjp2sdk-v5.2.1-linux.zip
$ chmod +x ERDAS_ECWJP2_SDK-5.2.1.bin
$ ./ERDAS_ECWJP2_SDK-5.2.1.bin
Choose Desktop Read-Only and accept the license. A directory named hexagon is extracted. Copy that to /usr/local.
$ sudo cp -r hexagon/ERDAS-ECW_JPEG_2000_SDK-5.2.1/Desktop_Read-Only /usr/local/hexagon
Link the .so library for the correct architecture:
$ sudo ln -s /usr/local/hexagon/lib/(x64|x86)/release/libNCSEcw.so /usr/local/lib/libNCSEcw.so
Then configure GDAL with this command:
$ ./configure --with-ecw=/usr/local/hexagon
Before I could see ECW support in gdalinfo --formats | grep -i ecw
I also had to run sudo ldconfig.
That was in Ubuntu 14.04 Linux.
I have tried in all ways to get wkhtmltopdf installed on our web server but unfortunately it is not getting installed. I cannot access user/bin folder as stated in a tutorial on installation.
On the server in public_html folder there is a sub folder _vti_bin, I copied the file wkhtmltopdf-i386 from wkhtmltopdf-0.9.1-static-i386, but I am not able to execute it.
How to install wkhtmltopdf on (shared hosting) web server and get it working?
I've managed to successfully install wkhtmltopdf-amd64 on my shared hosting account without root access.
Here's what i did:
Downloaded the relevant static binary v0.10.0 from here: http://code.google.com/p/wkhtmltopdf/downloads/list
EDIT: The above has moved to here
via ssh on my shared host typed the following:
$ wget {relavant url to binary from link above}
$ tar -xvf {filename of above wget'd file}
you'll then have the binary on your host and will be able to run it regardless of if its in the /usr/bin/ folder or not. (or at least i was able to)
To test:
$ ./wkhtmltopdf-amd64 http://www.example.com example.pdf
Note remember that if you're in the folder in which the executable is, you should probably preface it with ./ just to be sure.
Worked for me anyway
If you have sudo access...
Ubuntu 14.04 / 15.04 / 18.04:
sudo apt-get install wkhtmltopdf
# or
sudo apt install wkhtmltopdf
Others
Look at the other answers.
If its ubuntu then go ahead with this, already tested.:--
first, installing dependencies
sudo aptitude install openssl build-essential xorg libssl-dev
for 64bits OS
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2
mv wkhtmltopdf-amd64 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
for 32bits OS
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-i386.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-i386.tar.bz2
mv wkhtmltopdf-i386 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
Debian 8 Jessie
This works
sudo apt-get install wkhtmltopdf
Chances are that without full access to this server (due to being a hosted account) you are going to have problems. I would go so far as to say that I think it is a fruitless endeavor--they have to lock servers down in hosted environments for good reason.
Call your hosting company and make the request to them to install it, but don't expect a good response--they typically won't install very custom items for single users unless there is a really good reason (bug fixes for example).
Lastly, depending on how familiar you are with server administration and what you are paying for server hosting now consider something like http://www.slicehost.com. $20 a month will get you a low grade web server (256 ram) and you can install anything you want. However, if you are running multiple sites or have heavy load the cost will go up as you need larger servers.
GL!
Latest update for CentOS:
sudo yum install -y libpng libjpeg openssl icu libX11 libXext libXrender xorg-x11-fonts-Type1 xorg-x11-fonts-75dpi
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar -xvf wkhtmltox-0.12.4_linux-generic-amd64.tar
sudo mv wkhtmltox/bin/* /usr/local/bin/
check installation success: wkhtmltopdf -V
rm -rf wkhtmltox
rm -f wkhtmltox-0.12.4_linux-generic-amd64.tar
Place the wkhtmltopdf executable on the server and chmod it +x.
Create an executable shell script wrap.sh containing:
#!/bin/sh
export HOME="$PWD"
export LD_LIBRARY_PATH="$PWD/lib/"
exec $# 2>/dev/null
#exec $# 2>&1 # debug mode
Download needed shared objects for that architecture and place them an a folder named "lib":
lib/libfontconfig.so.1
lib/libfontconfig.so.1.3.0
lib/libfreetype.so.6
lib/libfreetype.so.6.3.18
lib/libX11.so.6 lib/libX11.so.6.2.0
lib/libXau.so.6 lib/libXau.so.6.0.0
lib/libxcb.so.1 lib/libxcb.so.1.0.0
lib/libxcb-xlib.so.0
lib/libxcb-xlib.so.0.0.0
lib/libXdmcp.so.6
lib/libXdmcp.so.6.0.0
lib/libXext.so.6 lib/libXext.so.6.4.0
(some of them are symlinks)
… and you're ready to go:
./wrap.sh ./wkhtmltopdf-amd64 --page-size A4 --disable-internal-links --disable-external-links "http://www.example.site/" out.pdf
If you experience font problems like squares for all the characters, define TrueType fonts explicitly:
#font-face {
font-family:Trebuchet MS;
font-style:normal;
font-weight:normal;
src:url("http://www.yourserver.tld/fonts/Trebuchet_MS.ttf");
format(TrueType);
}
List of stable versions wkhtmltopdf: http://wkhtmltopdf.org/downloads.html
Installing wkhtmltopdf on Debian 8.2 (jessie) x64:
sudo apt-get install xfonts-75dpi
sudo apt-get install xfonts-base
sudo wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-jessie-amd64.deb
sudo dpkg -i wkhtmltox-0.12.2.1_linux-jessie-amd64.deb
Shared hosting no ssh or shell access?
Here is how i did it;
Visit https://wkhtmltopdf.org/downloads.html and download the appropriate stable release for Linux. For my case I chose 32-bit
which is wkhtmltox-0.12.4_linux-generic-i386.tar.xz
Unzip to a folder on your local drive.
Upload the folder to public_html (or whichever location fits your need) using an FTP program just like any other file(s)
Change the binary paths in snappy.php file to point the appropriate files in the folder you just uploaded.
Bingo! there you have it. You should be able to generate PDF files.
A few things have changed since the top answers were added. They used to work out for me, but not quite anymore, so I have been hacking around for a bit and came up with the following solution for Ubuntu 16.04. For Ubuntu 14.04, see the comment at the bottom of the answer. Apologies if this doesn't work for shared hosting, but it seems like this is the goto answer for wkhtmltopdf installation instructions in general.
# Install dependencies
apt-get install libfontconfig \
zlib1g \
libfreetype6 \
libxrender1 \
libxext6 \
libx11-6
# TEMPORARY FIX! SEE: https://github.com/wkhtmltopdf/wkhtmltopdf/issues/3001
apt-get install libssl1.0.0=1.0.2g-1ubuntu4.8
apt-get install libssl-dev=1.0.2g-1ubuntu4.8
# Download, extract and move binary in place
curl -L -o wkhtmltopdf.tar.xz https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar -xf wkhtmltopdf.tar.xz
mv wkhtmltox/bin/wkhtmltopdf /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
Test it out:
wkhtmltopdf http://www.google.com google.pdf
You should now have a file named google.pdf in the current working directory.
This approach downloads the binary from the website, meaning that you can use the latest version instead of relying on package managers to be updated.
Note that as of today, my solution includes a temporary fix to this bug. I realize that the solution is really not great, but hopefully it can be removed soon. Be sure to check the status of the linked GitHub issue to see if the fix is still necessary when you read this answer!
For Ubuntu 14.04, you will need to downgrade to a different version of libssl. You can find the versions here. Anyways, be sure to consider the implications of downgrading libssl before doing so on any production server.
I hope this helps someone!
After trying, below command work for me
cd ~
yum install -y xorg-x11-fonts-75dpi xorg-x11-fonts-Type1 openssl git-core fontconfig
wget https://downloads.wkhtmltopdf.org/0.12/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar xvf wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
mv wkhtmltox/bin/wkhtmlto* /usr/bin
Version 12.5 of wkhtmltopdf only lists DEB files on their download page now. Being a mac user and not knowing much linux or what DEB files were I couldn't use the solutions posted.
This page helped me get past the knew twist of downloading a DEB file: http://www.g-loaded.eu/2008/01/28/how-to-extract-rpm-or-deb-packages/
Basically what I did was:
Downloaded from https://wkhtmltopdf.org/downloads.html
Unzipped the DEB file.
Unzipped data.tar.xz
Uploaded the binary in the unzipped 'usr' folder from step 3 (usr/local/bin/wkhtmltopdf)
Then I found out that the 'exec' function was disabled on my host. So make sure you can specifically run 'exec' if you're using PHP to run this. "Can I run the wkhtmltopdf binary" isn't specific enough. My fault.
