Debian/Ubuntu Linux都使用apt,升级时都是:

apt-get update

apt-get upgrade

apt-get dist-upgrade

但是常常有人会问,

upgrade和dist-upgrade有何不同,仔细查查,似乎大家对upgrade和dist-upgrade的解释都有点不同,在此也纪录自己的看法.

我认为apt-get

upgrade和dist-upgrade的差别:

upgrade:系统将现有的Package升级,如果有相依性的问题,而此相依性需要安装其它新的Package或影响到其它Package的相依性时,此Package就不会被升级,会保留下来.

dist-upgrade:可以聪明的解决相依性的问题,如果有相依性问题,需要安装/移除新的Package,就会试着去安装/移除它.

(所以通常这个会被认为是有点风险的升级)

apt-get upgrade 和 apt-get dist-upgrade 本质上是没有什么不同的。

只不过，dist-upgrade

会识别出当依赖关系改变的情形并作出处理，而upgrade对此情形不处理。

例如软件包 a 原先依赖 b c d，但是在源里面可能已经升级了，现在是 a 依赖 b c

e。这种情况下，dist-upgrade 会删除 d 安装 e，并把 a 软件包升级，而 upgrade 会认为依赖关系改变而拒绝升级 a

软件包。

MickeyDee Thanks for the reply, according to Unraid Dev team, it may happen this year.

Metaldololity Whoa, that's really simple. You just save my time a lot. Thankyou!

HopoL Since you’ve got the backup, it’s actually pretty simple. Just restore the backup files to your new flash drive, then head over to the /config directory and edit the go file. Look for export UNRAID_GUID=xxxxxxxxxxxxxx and swap it with your new drive's GUID. That should do the trick!

Metaldololity Really apreciate for your fast respond, mate. I actually have the backup of the flashdrive (from regular unraid backup). The problem is, when i search on youtube tutorial about changing the failed flashdrive, the process need some sort of confirmation with an account in unraid (blacklist the old one -> whitelist the new one). Since i have a cracked unraid, i don't know how to register my new flashdrive as the correct one (and the system not asking me for the old failed flashdrive). Thanks in advance

HopoL Man, that's a tough spot to be in. Regularly backing up your /boot folder is super important for exactly this reason. If you don't have a backup and your flash drive is completely fried, your best bet is to Google some specific recovery guides or check the Unraid forums. There are ways to rebuild your config by identifying your parity and data drives, but it can be a bit of a process. Hope you can get it sorted!
