# Misc Tips, TroubleShooting

## Sending commands to LXD containers
|
|
|
|
Use `bash -c "<command>"` for commands with wildcards. i.e.
|
|
|
|
```bash
|
|
for machine in $(lxc list | grep RUNNING | awk '{print $2}') ;\
|
|
do lxc exec "${machine}" -- bash -c "cat /etc/apt/apt.conf.d/02*" ; done
|
|
```
|
|
|
|
fish shell is actually a little bit cleaner
|
|
|
|
```fish
|
|
for machine in (lxc list | grep RUNNING | awk '{print $2}') ; \
|
|
lxc exec $machine -- bash -c "cat /etc/apt/apt.conf.d/02*" ; end
|
|
```
|
|
|
|
```fish
|
|
# change all their time zones
|
|
for machine in (lxc list | grep RUNNING | awk '{print $2}') ; \
|
|
lxc exec $machine -- bash -c "timedatectl set-timezone America/Los_Angeles" ; end
|
|
# check to see if anyone is logged in before rebooting
|
|
for machine in (lxc list | grep RUNNING | awk '{print $2}') ; echo ; \
|
|
echo $machine ; lxc exec $machine -- bash -c "who" ; end
|
|
```

## Ubuntu-Mate-Welcome-Center doesn't work some for some repos
|
|
|
|
Perhaps your apt-cacher-ng proxy server isn't configured to allow
|
|
traffic through from https sources. Make sure the following is
|
|
uncommented. This applies for all PPA's that use https.
|
|
|
|
```conf
|
|
# /etc/apt-cacher-ng/acng.conf
|
|
PassThroughPattern: .*
|
|
```
