It's kind of weird to be root in a machine and unable to install a package because of the PATH, hence those questions.<br><br></div><div>Looking at the templates, it seems they export that PATH<br></div><div><br>➜ ~ grep PATH /usr/share/lxc/templates/lxc-ubuntu<br># Make sure the usual locations are in PATH<br>export PATH=$PATH:/usr/sbin:/usr/bin:/sbin:/bin<br><br></div><div>So the -t download switch doesn't use that ?<br><br><br></div><div>Thanks in advance<br></div><div><br><br><div><div><div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr">benoit barthelet<br><a href="http://pgp.mit.edu/pks/lookup?op=get&search=0xF150E01A72F6D2EE" target="_blank">http://pgp.mit.edu/pks/lookup?op=get&search=0xF150E01A72F6D2EE</a><br></div></div></div></div>
