Please suggest what commands to use.

Do a git pull to update the xschem cloned directory, then do a

sudo make uninstall

before configuring, building and installing again.

@Stefan Schippers i reinstalled xschem as per above suggestions and it got installed at path

/usr/local/share

. But xschem is sourcing from some other location in m setup as seen in screenshot. Don't know how it came in this path. Please suggest how to remove it so that latest updated version only is sourced.

remove the following:

rm  ~/bin/xschem
rm ~/share/man/man1/xschem.1
rm -rf ~/share/xschem
rm -rf ~/share/doc/xschem

I manually removed all xschem directories and then configured, build and installed xschem again. But xschem is not installed .

which xschem

command returns no output.

try:

ls /usr/locall/bin/xschem

if it is not there then go in the xschem source directory and type:

sudo make install

It worked with

sudo apt install

. Xschem is invoking. Thanks @Stefan Schippers
