Hi Kornel, hallo Jürgen,
I have TL2016 installed and could call GUI in a console as user.
However, I could not edit, update etc. because I had no write permission
for /usr/local/texlive/2016/tlpkg.
I was advised to call tlmgr as administrator but didn't find out how to
do that (su, sudo, xsudo etc. did NOT work!).
So, I eventually changed the permissions to rwx and informed Kornel
about it. He found this weird and frankly, so did I.
https://www.tug.org/texlive/pkgupdat deals with updating packages in TeX
Live.
It says there that one needs "... a writable TL source tree..."with
emphasis on the word writable.
Is this not exactly what I did?
Thanks and cheers,
Michael
