I initially installed protobuf 3.13.0 and then used apt remove to remove it but it is not getting removed.
I even installed protobuf 3.6.1 from source following these instructions but still 3.13.0 is in place

I noticed I have:
$ which -a protoc /home/mona/anaconda3/bin/protoc /usr/local/bin/protoc I added the last line in ~/.bashrc:
$ tail ~/.bashrc alias vi='vim' aa_prompt_defaults alias bat='batcat' alias fd='fdfind' alias protoc=/usr/local/bin/protoc then:
$ source ~/.bashrc now:
$ protoc --version libprotoc 3.6.1
