Package: autopkgtest Version: 5.28 Severity: normal X-Debbugs-Cc: deb...@rocketjump.eu
Hi, issue is that setup-testbed will break networking config of a VM by writing a broken config file, e.g. /etc/network/interfaces/enp0s31f6\nenx482ae3598891 with the following contents: auto enp0s31f6 enx482ae3598891 iface enp0s31f6 enx482ae3598891 iface dhcp The reason is the following: I'm calling setup-testbed from within vmdb2, which will chroot into the filesystem before executing the command. As such, $root=/ and line 429 [0] will evaluate to true. In the next step, `cd /sys/class/net; ls -d e* 2>/dev/null` is run, which returns two network interfaces on my machine: enp0s31f6 and enx482ae3598891. And a few steps later the above broken ifupdown config file will be written out. There are several problems with the code: First, it assumes that if being run with $root=/ that it's already in a VM, whereas it can be running in a chroot. The second problem is that if `ls -d e*` returns more than one line the config it creates will be broken. In a step not completely clear to me network-manager then gets removed in line 620 [1]. I at least can't make out any package there that network-manager depends on. I was able to work around this (admittedly hilarious) bug by setting AUTOPKGTEST_IS_SETUP_COMMAND=1.
