TeX Live and MacTeX ⇒ Update a single package in Linux / Ubuntu

[Tolaso]

tcolorbox package has been updated. How can I update it my installation? I don't want to update the entire TeX Live installation. I just want to update this package only.

When I ran the command sudo -i tlmgr update tcolorbox in the terminal I'm getting this

Code: Select all

cannot setup TLPDB in /root/texmf at /usr/bin/tlmgr line 5604.

I suspect the error message is because the TeX Live distribution is frozen? Maybe I'm wrong though.

Which version of TeX Live are you using? And is it installed via tug.org, or using the Ubuntu installation via Ubuntu repositories?

Stefan

[Tolaso]

I installed TeX Live through Ubuntu terminal. I am using TeX Live 2016.

[Stefan Kottwitz]

Yes, with TeX Live 2016 (or 2018) you cannot use the automatic update anymore. The repositories don't support older years than the current year, this cannot be managed.

One solution would be: install (download) the package to your home directory. Check

kpsewhich tcolorbox.sty

and

kpsewhich -var-value TEXMFHOME

to find your own (user) directory and copy it there in a simlar way with folder and subfolder.

The user home directory is preferred over the system TeX directory, so the newer tcolorbox would be used.

Is it me or just my imagination that I don't understand the procedure? I have downloaded the zip file. What to do next? Run something through the terminal?

[Stefan Kottwitz]

Download tcolorbox.tds.zip, copy it directly in the TEXMFHOME directory, unzip it there.

Stefan

[Tolaso]

Thanks Stefan but I cannot seem to locate the TEXMFHOME directory. Any guidance?

[Stefan Kottwitz]

Did you try?

kpsewhich -var-value TEXMFHOME

kpsewhich --expand-path='$TEXMFHOME'

kpsewhich -var TEXMFHOME

Sorry Stefan,

I'm quite new to Linux and I don't understand these steps! Would you mind elaborating a bit? Do I run these commands through the terminal to see the directory?

[Stefan Kottwitz]

Yes, run the commands in a terminal window. The output should be the user TeX home directory.
