Upgrade from TeX Live 2013 to 2014
By default, please get the new TL by doing a new installation instead of
That is, you should have a specific reason to do this upgrade
(instead of a new install), and you should be familiar with Unix and TeX
Live. If you have any doubts whatsoever, please do a new installation.
We do not provide a dedicated upgrade script. The procedure here is
not bullet-proof, or recommended; consider it provided as-is, to be used
at your own risk, if you want to do so, for reasons of your own. It's
your responsibility to understand what is being done, etc. Failing any
of that, please do a new installation.
These instructions say nothing about what is done as root or as a
normal user; that's because TeX Live installations are done both ways
(root is not required for anything in TL itself), and we can't know
which you chose. You need to know. If you don't, do a new
- Find the parent directory of the current installation; it's
/usr/local/texlive by default.
- Copy the whole directory 2013 to 2014, preserving
symbolic links; for example:
cp -a 2013 2014
If you don't understand this, stop here and do a regular installation.
- To save some space, you can exclude tlpkg/backups/* or
remove them from the 2014/ directory afterwards.
(Theoretically, you could rename 2013 to 2014,
but we strongly advise against this, since you may lose your
existing installation with no good way back.)
- If you installed symlinks in system directories (via the installer
option or tlmgr path add), remove them now with
tlmgr path remove.
- As needed, adjust your PATH in your startup files to
point to .../2014/bin/platform instead of
- Log out and log in, and confirm that your PATH now has
the 2014 directory. This is crucial. Your PATH must use the
- cd to your top-level .../2014 directory.
- Download the latest
update-tlmgr-latest.sh and run it like this:
sh update-tlmgr-latest.sh -- --upgrade
(The extra options try to prevent the upgrade from happening
- If you don't want to use the default repository (that is, the
automatic CTAN redirection) for downloading the new files, run as usual:
tlmgr option repository yourrepo
- Run (with patience, it will be downloading all the new material):
tlmgr update --self --all
- If you want symlinks in system directories (not recommended),
run tlmgr path add.
- When you are happy with how the new TL is working, if you wish
you can remove the old installation by running .../2013/.../tlmgr
uninstall (full tlmgr doc). Not
recommended, since you might always find a document that doesn't work
with the new version, just at the wrong time …
Good luck, and to reiterate from the top, don't do any of this if it
doesn't make sense to you. Just do a fresh installation.
There is no comparable upgrade procedure for Windows. Doing a normal
new installation is necessary.
