installinglinuxtexlive
I am currently having massive issues getting TeX Live to run on Ubuntu 12.04, so I am considering running a VM on VirtualBox with another Linux distribution that has better support for the latest TeX Live (2012).
I want to have automatic package manager installation a la apt and synaptic and don't want to interfere with the system.
What would you recommend to me?
from dcmst's answer --
user@host:~$ tlmgr install collection-fontsrecommended
Some systems might require to run tlmgr as root, so add sudo:
user@host:~$ sudo tlmgr install collection-fontsrecommended
This looks very much like a permissions problem. I've encountered this when I've done an installation using tlmgr, though I'm surprised at its rearing its ugly head when installation is done using apt-get.
At some point in the installation, files were installed that were only usable by the root account. That is, ordinary users do not have permission to read the necessary files for latex to work.
In brief, every file and directory on a UNIX system has three sets of three permissions (sort of). The three sets are: owner, group, world and the three permissions are read, write, execute. In order to use a file or directory you have to have sufficient permissions to carry out the activity. Which permissions apply depend on your relationship to the file (or directory) in question. For the files installed in a TeXLive installation, the most likely situation is that you do not own the files (root does) nor are you in the same group as the files (probably something like admin) so the world permissions apply to you. When you do ls -l <file name> then the first block looks something like -rw-r--r--. It is the last three that therefore concern you. What you need is to have r-- for ordinary files and r-x for directories and executable files.
To check this hypothesis, you need to find the permissions of (some of) the files. From the comments, the first thing to try is:
ls -l /usr/share/texmf-texlive/tex/latex/base/article.cls
With a bit of luck, this will complain:
cannot access /usr/share/texmf-texlive/tex/latex/base/article.cls: Permission denied
If so, it's a permissions problem. (It might be that the message is cannot open directory and that the path is only a part of the path given.)
When software is installed, it tries to install it as permissively as possible so that any user can use it. However, when you create a file in your own directory you don't want this behaviour: you want it so that you can use it, but no other user can do so. Unfortunately, the system can't tell the difference between these two cases and just sees the instruction "Create a file/directory". Now you can say "Create a file/directory with these permissions" but then that's hard for a user to override if they want to do a local installation. So what happens is the request is "Create a file/directory and suggest these permissions". The "suggestion" is then matched against something called the umask to get the real permissions. You can think of the umask as a polariser: it only allows certain permissions to get through.
Permissions are stored as octal numbers, with 4 = read, 2 = write, 1 = executable. An installer might say "This is an executable file, I suggest permissions 755" meaning everyone can read and execute it, and the owner can write to it. This is then checked against the umask to see which of these permissions can be set. A common user umask is 077. This allows through all user permissions but none of the others so the resulting file permissions are 700. On the other hand, the standard umask for a system installation is 022. This guards against files being writeable by non-owners but otherwise lets everything else through. Then the 755 would work.
What is likely to have happened here is that the umask in effect was 077 instead of 022. This can sometimes happen when using sudo since then the umask is not changed from its user setting. To avoid this happening again, the command umask 022 changes the umask to 022 (umask by itself displays the current setting) so this can be done before the installation, and then reset afterwards.
(However, as I said, I'm a little surprised at this happening with apt-get since I would expect that to be umask-savvy and sort itself out. tlmgr does not, though.)
Deleting and reinstalling is one option, but given the size of TeXLive it's a bit of a sledgehammer. A little more refined is fixing the permissions.
The first thing to do is work out where the problem starts. To do that, start with the article.cls path that you have and find out where you first lose permission:
ls -l /usr/share/texmf-texlive/tex/latex/base/article.cls
ls -ld /usr/share/texmf-texlive/tex/latex/base
ls -ld /usr/share/texmf-texlive/tex/latex
ls -ld /usr/share/texmf-texlive/tex
ls -ld /usr/share/texmf-texlive
ls -ld /usr/share
(If you get to the bottom one and still have problems, then you have big problems.)
Most likely, it is /usr/share/texmf-texlive. Next is to get a sense of the scale of the problem:
sudo find /usr/share/texmf-texlive -not -perm -004
This gives you a list of all the files and folders below texmf-texlive which are not world-readable. It might just be that it is only the top directory that has the wrong permissions, if so then do the following:
sudo chmod 755 /usr/share/texmf-texliveIf the list is very short, you can do something similar to the above on each of the files/directories. The rules are that the permission to give is whatever the owner has without the writeable one. chmod can take "symbolic" permissions so you don't have to remember the octal notation (symbolic is actually better here as the syntax for adding permissions is simple). In short:
sudo ls -l <filename>drwx, -rwx, or -rw-sudo chmod go+rx <filename>sudo chmod go+r <filename>If the list is quite long, going through each one is a pain. Fortunately, find can iterate through the list of files and execute a command on each one. We have to do it twice to fix the two situations.
First, we go through and add the read bit to all files and folders.
sudo find /usr/share/texmf-texlive -not -perm -004 -exec chmod go+r {} ';'
Then, we go through and add the execute bit to all executable files and all folders.
sudo find /usr/share/texmf-texlive -perm +100 -not -perm -001 -exec chmod go+x {} ';'
At this point, everything should have the right permissions.
There is a faint chance that there are some files which aren't meant to be world readable in the TeXLive tree, or executable files which aren't meant to be executable by anyone but root. However, I doubt that.
(Unfortunately, as I can't guarantee that my last TL installation didn't need this permission fix, I can't trust that the permissions in my installation are all as they were intended so I can't test this myself.)
Best Answer
Practically all big distributions have already switched to TL2012 or their upcoming release includes 2012. Debian/wheezy (currently testing, will be released soon) ships 2012, and I have already more uptodate packages of current tlnet in Debian/experimental.
Ubuntu from 12.10 onward includes TL2012 by default (same packages as in Debian). For 12.04 you need to use the mentioned PPA.
For Fedora 16,17,18 there are TL2012 packages, in 18 it is included (unsure here!)
openSuSE 12.2 has TL2011 package and TL2012 from an additional repository, openSuSE dev contains TL2012 by default.
FreeBSD and OpenBSD has TL2012 in the ports
NetBSD is in progress
Mac has MacTeX which is a repackaged TL2012, so you always get the latest updates, plus a nice integration.
Hope that gives a small overview on what is available.
