On my Fairphone 2 I have installed Ubuntu Touch OTA-18.
I would like to install e/OS on it.
Can I follow the standard procedure as described on
https://doc.e.foundation/devices/FP2/install
to do so?

Yes, it’s totally sufficient do follow the standard procedure.

Thanks for your reply.
What do I do, if the Ubuntu-FP2 is not found?

adb reboot bootloader
error: no devices/emulators found

adb devices
List of devices attached

Thanks for your help.

ADB is the Android Debug Bridge … so I suspect Ubuntu Touch doesn’t have it.

Just start or reboot the phone while keeping Vol - pressed to get into bootloader (=Fastboot Mode).
Keeping the power button pressed for about 15 seconds should force a reboot.

In case you’re wondering about adb reboot recovery later on, just start or reboot the phone while keeping Vol + pressed to get into recovery.

Actually Ubuntu Touch does have adb. It’s enabled as “developer mode” in Settings > About
https://docs.ubports.com/en/latest/userguide/advanceduse/adb.html

But yes, using the buttons to boot into the correct mode is a good option as well.

Thanks. That worked fine.
Point 4 of the instruction completed successfully:

fastboot flash recovery twrp-3.5.2_9-0-FP2.img

But I do not know how to do (5)
Now reboot into recovery to verify the installation.
Pressing Power Off button does not have any effect.
I could take the battery out. I did this to install Ubuntu Touch.

Taking out the battery at this point would be wrong.

After flashing TWRP like you just did, you need to boot into TWRP before anything else. Otherwise TWRP will vanish automatically.

After fastboot flash recovery twrp-3.5.2_9-0-FP2.img and while you’re still in fastboot mode, you can hold the Power Down button and execute fastboot reboot. Keep the Power Down button pressed all the time until you see that TWRP is running.

Thanks for your help. Actually I continued before your reply.
I rebooted into Ubuntu Touch using fastboot reboot.
Then I have switched off the phone and booted in to recovery.

Now I have a running e on my Fairphone 2.
Thanks @Ingo_FP_Angel and @AnotherElk for your help!
