I am aware there are many threads related to "l3kernel too old" but did not find them helpful.
I work in Ubuntu with TexLive 2016:
tex --version TeX 3.14159265 (TeX Live 2016)
/usr/local/texlive/2016/bin/x86_64-linux is added to the PATH.
It was installed as described in
Trying to update l3kernel by running
sudo tlmgr update l3kernel
I get the following information:
TeX Live 2015 is frozen forever and will no longer be updated. This happens in preparation for a new release. You may want to try specifying an explicit or different CTAN mirror; see the information and examples for the -repository option at http://tug.org/texlive/doc/install-tl.html (or in the output of install-tl --help). TeX Live 2015 is frozen forever and will no longer be updated. This happens in preparation for a new release. If you're interested in helping to pretest the new release (when pretests are available), please read http://tug.org/texlive/pretest.html. Otherwise, just wait, and the new release will be ready in due time.
When trying to switch to another mirror I get checksum problems which I reported in tlmgr, changing repository, containerchecksum
The pretest is over. See you next year.
- Is the only solution " just wait, and the new release will be ready in due time"? I need to compile the latex document before the new release is released.
