I tried finding all pharo locations:

hedster:/$ whereis pharo

pharo: /usr/bin/pharo /usr/lib/x86_64-linux-gnu/pharo9.0 /snap/bin/pharo /snap/bin/pharo.getimage /snap/bin/pharo.cleanimage32 /snap/bin/pharo.getimage32 /snap/bin/pharo.cleanimage /snap/bin/pharo.config /snap/bin/pharo.ui /snap/bin/pharo.sqlite3

Hope this helps.

Regards,

Hedster
