Uninstalled metapackage trisquel-mini, lost WiFi
I am a member!
I broke my system. I tried the following. I am stuck. I need help.
Started on Trisquel Mini. Uninstalled metapackage trisquel-mini.
sudo apt-get remove trisquel-mini
No NetworkManager, lost WiFi. Solution: reinstall NetworkManager without WiFi.
Booted live Trisquel. Decrypted Trisquel Mini root volume.
Chrooted to Trisquel Mini root volume.
sudo chroot /media/trisquel/ee2acd05-1b50-470f-add3-cebc0298a5ee/ bash
Installed NetworkManager in chroot.

Bump.
Demoted my own post by commenting on another thread.
If you really want to try and follow the Live CD+decryption+chroot
route, then by all means feel free, but chrooting into encrypted
partitions can be really finnicky, and that is the cause of all those
weird errors (the chrooting itself, which is hardly ideal, and the
encryption).
There is a far easier way to escape from all this pandemonium. But
first, is your wifi network open, or does it use WEP or WPA? This will
determine the tools required.

Open.
Wunderbar. That means you can avoid having to configure wpa_supplicant.
Boot the installed system, and (I'm assuming it's in text mode, since
trisquel-mini contains the DE as well) run the following (as root):
ifconfig up
In the vast majority of cases this will be wlan0, so:
ifconfig wlan0 up
If not you can find out by running ifconfig without arguments, and it
will list your network interfaces. Then:
iwconfig wlan0 essid
replacing with the name of your wireless network.
dhclient wlan0
This will assign your computer an IP fetched from a DHCP server, and is
the last step. You should now have a network connection, if your wifi is
open as you say. Try:
apt-get update
apt-get install trisquel-mini
and see if it now works.

Success! I now have WiFi. I'm hoping that Trisquel Mini will appear when I reboot.
I had strange messages when I booted my computer. They looked quite bad. The dmesg output is attached.
# ifconfig up up: error fetching interface information: Device not found
However, ifconfig wlan0 up did work.
# ifconfig wlan0 essid ATT2G3X2z5
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device wlan0 ; Operation already in progress.
Ping to example.net succeeded.

You probably have some sort of WLAN autoconnection set up. I didn't know
Trisquel did that. By the way, it's iwconfig for this step, not
ifconfig.
Anyway, congratulations on getting it working. You'll have to tell me
whether Trisquel Mini did indeed appear on boot.
PS. You mentioned attached dmesg output- there were no attachments. Are
you sure you sent some? Maybe Drupal stripped them.

Rebooting. I hope Trisquel Mini shows up.
If not, I'll have a nice burger to cheer me up.
Sorry. I'm doing all of this through the mailing lists- when you said
attachment I was expecting to find and *e-mail* attachment. Sorry.
'sudo apt-get remove trisquel-mini' did not make you lose Wifi support. It is a meta-package. It does nothing by itself. Maybe you ran 'sudo apt-get autoremove' afterwards and confirmed the remotion of packages that should have been kept.
