I ran into this issue (sometimes missing error output) when I was running `sudo proxmox-backup-client mount [...]` and forgot that PBS_REPOSITORY was not passed through by sudo. It looks like in this case, the patch doesn't completely fix this issue -- seems like I'm still missing the error output sometimes: $ sudo ./proxmox-backup-client mount \ "$SNAPSHOT" $FILE $PATH \ --keyfile $KEYFILE --ns $NS $ sudo ./proxmox-backup-client mount \ "$SNAPSHOT" $FILE $PATH \ --keyfile $KEYFILE --ns $NS $ sudo ./proxmox-backup-client mount \ "$SNAPSHOT" $FILE $PATH \ --keyfile $KEYFILE --ns $NS Error: unable to get (default) repository On 14/06/2024 11:39, Gabriel Goller wrote: > When using the `proxmox-backup-client mount` command, the parent sometimes > exits before we can print any error message.
