我有较旧的 Debian Jessie 服务器，其中装有 Mercurial 3.1.2 和 Phabricator。长期以来，Phabricator 一直抱怨 HG 太旧，存在安全问题，因此我决定使用最新的 HG 制作全新的 VM。旧版：
lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 8.11 (jessie)
Release: 8.11
Codename: jessie
hg version
Mercurial Distributed SCM (version 3.1.2)
(see http://mercurial.selenic.com for more information)
新的：
Distributor ID: Debian
Description: Debian GNU/Linux 10 (buster)
Release: 10
Codename: buster
hg version
Mercurial Distributed SCM (version 4.8.2)
(see https://mercurial-scm.org for more information)

对所有存储库进行 Rsynced，并将 hgweb.wsgi 设置为 Web 服务器（Apache2 vhost，对我来说很容易）
# An example WSGI for use with mod_wsgi, edit as necessary
# See https://mercurial-scm.org/wiki/modwsgi for more information
# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/var/www/vhost/hg/cgi-bin/hgweb.config"
# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")
# Uncomment to send python tracebacks to the browser if an error occurs:
import cgitb; cgitb.enable()
# enable demandloading to reduce startup time
from mercurial import demandimport; demandimport.enable()
from mercurial.hgweb.hgwebdir_mod import hgwebdir
import os
os.environ["HGENCODING"] = "UTF-8"
from mercurial.hgweb import hgweb
application = hgweb(config)
Python版本是：

[GCC 8.3.0] on linux2
当推送大文件时我收到错误：

我整天都在努力尝试，也尝试了各种调整和建议，但是都没有成功 :/
有人能提供一些建议吗？
PS：还尝试克隆旧的>>推送新的一些存储库，但仍然不行
答案1
部分解决问题 - 用户克隆的存储库现在可以hg push repo
添加到 /etc/mercurial/hgrc，但以下情况除外：
[extensions]
largefiles =
和
[largefiles]
usercache = /path/to/largefiles/storage
仍然面临如何将所有转发从旧服务器迁移到新服务器的问题。如果我找到合适的解决方案，我会编辑主题。
