From 671c7b38545079136f804e0fb5b77e21f0dba44f Mon Sep 17 00:00:00 2001 From: Werner Llácer Date: Wed, 10 Nov 2021 11:20:38 +0100 Subject: Solves issue #689. Attribute Error.'None type' has no attribute 'format' ... It seems the system does not syncronus update its internal information after a partitioning. Two places are affected. Directly on filesystem.add_partition (the uuid of the new partition isn't available after the parted command) and blockdevice.get_partition, where the list of partitions for the iterator might not be available in the query. The patch places both sections under controlled loops, giving the system the chance to update the information. Should be more controlled via application parameters --- archinstall/lib/disk/blockdevice.py | 17 ++++++++++++++--- archinstall/lib/disk/filesystem.py | 26 +++++++++++++++----------- 2 files changed, 29 insertions(+), 14 deletions(-) (limited to 'archinstall/lib/disk') diff --git a/archinstall/lib/disk/blockdevice.py b/archinstall/lib/disk/blockdevice.py index 048e51f4..493e5383 100644 --- a/archinstall/lib/disk/blockdevice.py +++ b/archinstall/lib/disk/blockdevice.py @@ -1,9 +1,11 @@ import os import json import logging +import time from ..exceptions import DiskError from ..output import log from ..general import SysCommand +from ..storage import storage GIGA = 2 ** 30 @@ -213,6 +215,15 @@ class BlockDevice: self.part_cache = {} def get_partition(self, uuid): - for partition in self: - if partition.uuid == uuid: - return partition + count = 0 + while count < 5: + for partition in self: + if partition.uuid == uuid: + return partition + else: + log(f"uuid {uuid} not found.
