Hi Abdelfatah,
Looks like file is missing in directory disk0:/asr9k-base-4.3.2/0x100309. You can check with below commands
ls /disk0:/asr9k-base-4.3.2/0x100309/bin
ls /disk0:/asr9k-base-4.3.2/0x100309/startup
If files canb_fc_upg_agt and canb_fc_upg_agt.startup are missing, you can copy same from any other router running with same image and copy to same directory. It wont be service impacting. you can do it on production router.
To copy you can use sftp, as below
Lab-router-1#sftp <ip address of peer router>
Connecting to x.x.x.x...

sftp> get /disk0:/asr9k-base-4.3.2/0x100309
