Flashing twrp failed on Moto G5s

I wanted to install twrp on Moto G5s but faced the following error:

Inspiron-7501:~/Downloads$ fastboot flash recovery twrp-3.5.img
(bootloader) is-logical:recovery: not found
Sending 'recovery' (15714 KB)                      OKAY [  0.711s]
Writing 'recovery'                                 (bootloader) Image not signed or corrupt
OKAY [  0.132s]
Finished. Total time: 0.848s

I tried multiple recovery images, including lineage recovery, and, as i mentioned, twrp. I checked for the right files for my device (montana) and unlocked the bootloader previously. If someone has an idea, i would appreciate some help. Thanks in advance, Bennett.
