p4lang-bmv2 disappear after it is installed by apt

[10212]

In the Ubuntu20.04，I install bmv2 by below cmd:
. /etc/os-release echo "deb http://download.opensuse.org/repositories/home:/p4lang/xUbuntu_${VERSION_ID}/ /" | sudo tee /etc/apt/sources.list.d/home:p4lang.list curl -fsSL "https://download.opensuse.org/repositories/home:p4lang/xUbuntu_${VERSION_ID}/Release.key" | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_p4lang.gpg > /dev/null sudo apt update sudo apt install p4lang-bmv2
And I've successfully run simple switch with p4c. But when I tried to change some bmv2 configuration conditions, I found that I couldn't find it , even though I had installed it through apt

@10212 Could you describe what were the configuration conditions and how did you change them?

I installed bmv2 with apt and compiled simple_switch with p4c, and simple_switch is still available.
I can also use apt show to view bmv2 information like this:
c410@410:~$ apt show p4lang-bmv2
Package: p4lang-bmv2
Version: 1.15.0-3
Priority: optional
Section: net
Maintainer: Radostin Stoyanov <radostin@stoyanov.io>
Installed-Size: 63.3 MB
I also searched for places where apt downloads might exist, such as usr/local and several other locations, still not found.
As for how to configure it, I first created a new test.p4 file and compiled it through p4c:
p4c -b bmv2 test.p4 -o test.bmv2
sudo simple_switch --interface 0@veth0 --interface 1@veth2 --interface 2@veth4 test.bmv2/test.json &
The main configuration is shown above.
although simpleswitch is currently available,I can't find bmv2 folder...

@10212 Thank you for this information. Could you run the following commands and show the output of the last two?

sudo apt-get update
sudo apt-get purge -y p4lang-bmv2
sudo apt-get autoremove
sudo apt-get install -y p4lang-bmv2

which simple_switch
simple_switch --version

Although I did not reinstall the bmv2, the output is as follows:
c410@410:~/p4$ which simple_switch
/usr/local/bin/simple_switch
c410@410:~/p4$ simple_switch --version
1.15.0-e9fa7dc6
Following your prompts to reinstall it, it shows the same information
in usr/local/bin 'ls' show
bm_CLI bm_p4dbg p4c p4c-bm2-ss p4c-ebpf p4c-ubpf pi_convert_p4info pi_gen_native_json psa_switch_CLI simple_switch_CLI bm_nanomsg_events p4c-bm2-psa p4c-dpdk p4c-graphs p4test pi_gen_fe_defines psa_switch simple_switch thrift
Does that make it complete? I was trying to find out if the bmv2 folder was wrong.

@10212 It looks like you have two versions of BMv2 installed on your system.
One is installed from source in /usr/local/ and the other is installed from the p4lang-bmv2 package in /usr.

Could you run the following commands to confirm this?

/usr/local/bin/simple_switch --version
/usr/bin/simple_switch --version
