Jail Creation Fails!

Are you seeing this error?

ELF interpreter /libexec/ld-elf.so.1 not found, error 2

This can happen if during jail creation iocage create -r <release>, a FreeBSD RELEASE is being downloaded, but the operation is interrupted. The places the downloaded release in an indeterminate state, which results in the error if jail creation is reattempted.

To fix this error:

1. First ascertain what <release> you were trying to download.
2. Refetch it iocage fetch.

That’s it! Jail creation for that release should work again. In the example below, I had aborted the running of a script during a RELEASE fetch operation. When I ran the script again, it would fail.

# ./rslsync-jail.sh
JAIL_INTERFACES not set, defaulting to: vnet0:bridge0
POOL_PATH defaulting to /mnt/tank
rslsync successfully created!

Stopped rslsync due to VNET failure
Failed to create jail

I refetched the RELEASE after determining it as 12.2 (current at the time).

iocage fetch
[0] 11.2-RELEASE (EOL)
[1] 11.3-RELEASE (EOL)
[2] 11.4-RELEASE
[3] 12.0-RELEASE (EOL)

Running the script was thereafter successful.
