After installing TexLive 2019 on this Linux Package, I'd tried to execute the following command in terminal:
tlmgr --repository https://contrib.texlive.info/current install harftex
but it gave me following message:
(running on Debian, switching to user mode!) Cannot determine type of tlpdb from /home/emon/texmf! cannot setup TLPDB in /home/emon/texmf at /usr/bin/tlmgr line 6424.
So I'd to prepend the full path of tlmgr of TexLive 2019 like this
/usr/local/texlive/2019/bin/x86_64-linux/tlmgr to install harftex!
Before adding the new path in
/etc/environment, I've to know, how to remove the old version of TexLive (probably of 2017) that comes by default with this Linux Package?
