Is there any evidence or research into the likelihood, as well as damage, via threats in previous versions compared to following iterations of software?
For example, with every software version is the likelihood of new security vulnerabilities. More importantly, those vulnerabilities will be unknown. Whereas by staying on the previous version, even if you’re now vulnerable to a possibly existing risk, it may be a threat that is documented. Of course, that may not always be the case but if it is an unknown threat in version 1, than it will be an unknown threat in version 1+. If that threat is mitigated in version 1+, than we’re back to the point of this question:
**unknown and known threats in
- Version 1: unknown and known threats, versus
- Version 1+:unknown and possible introduction of alternative threats
This is not a duplicate of other questions with similar titles because Im looking for facts, whereas a lot of other posts include much conjecture.
Trying to get a handle on upgrade implications. When I try and install the new MSOLEDBSQL driver, Windows says “A lower version of this product has been detected on your system. Would you like to upgrade…”. I am presuming that refers to the existing SQLOLEDB driver, and that updating will break my ability to use all of the applications that use PROVIDER=SQLOLEDB.1? I’d like to use the new driver for the current project and moving forward, but wasn’t planning to upgrade every application (and every user’s installed driver, etc) just yet.
1) Is the new driver backward compatible without updating all the connection strings? 2) Can I roll back the old driver anytime? (I didn’t see a download for it anywhere since it’s deprecated.)
As you may already know old Openssl versions were vulnerable(OpenSSL
1.0.1f (inclusive)) by the
HeartBleed vulnerability. currenly our server is running Tomcat7 which is built in a vulnerable Openssl, so we upgraded into Tomcat8 but we didn’t regenerated the SSL certeficates.
So my question is I wonder if we should regenerate the SSL certeficates with the new installed version Openssl, to avoid the Heartbleed vulnerability and may be performance issues?
Thanks for your help!
I have a two-and-a-half year old Gazelle laptop from System 76. It shipped with Ubuntu 18 installed. There’s no CD drive, internal or external.
I (foolishly) decided to upgrade from 18 to 19 last night.
It downloaded, installed, and cleaned up without incident. I rebooted and left it running when I went to bed.
It’s still running this morning.
I see the following message:
A start job is running for /dev/mapper/cryptswap1 [11h 39 s/no limit]
I also saw a message about crypt size needing to be set.
Have I bricked my laptop? What next steps could I take to restore it?
I am using Dropbox on ubuntu (16.04) and noticed that the Dropbox folder contains a folder
.dropbox.cache which in turn contains a folder
temp_dirs containing 155(!) folders named
3ac3119f-3990-13c1-d09f-3b5d2d124a92 and the like, 75 of which contain files all named
dropbox-upgrade-81.4.195.tar.gz and each is 98.1 MB big.
The total size of these files is thus about 7.5 GB.
The Dropbox menu says
Upgrading Dropbox... and I understand that these files might be related to the upgrade, but the hard drive does not have enough disk space to fill all 155 folders with 100 MB files and I find it strange that 7.5 GB worth of upgrade files would be needed to upgrade a 339 KB package…
Does anyone have an idea what is going on here?
I upgraded the firmware of my Lenovo T480 (via Ubuntu’s “application store”) and everything went fine except that I was running 4.18 kernel before and now it did not boot anymore due to some signature problem (Secure Boot is enabled). No problem, I just selected 4.15 from boot menu and it still worked (why?).
So, I installed the newest 5.0.0-27. However, after reboot I noticed that USB didn’t work, WLAN didn’t and even the external display didn’t work anymore. Then I installed 4.17. Same problem. It seems that only the default 4.15 now works.
Any ideas what has happened?
There are no errors when installing the other kernels. It’s just after reboot I’m lacking USB, WLAN and HDMI. Otherwise the kernels seem to work.
Currently running 19.4 and waiting for the stable release of 19.10
When it comes out, the update is done entirely through the OS and doesn’t involve booting from USB or DVD right ?
I’m trying to upgrade from:
$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.6 LTS Release: 16.04 Codename: xenial
$ sudo do-release-upgrade but got
Please install all available updates for your release before upgrading. So I tried that and executed
sudo apt-get -u dist-upgrade, it downloaded a bunch of packages and then showed something like:

I then tried
sudo apt install -f and
sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade but didn’t get any further… ghow do i best proceed to get my distribution up-to-date?
What is the difference between updating just the kernel (downloading and compiling) and
sudo apt dist-upgrade?
I’ve read this, but I mean what if I just install the new kernel? (Download kernel 5 from here and install it on my Xubuntu 16.04). Will programs and GUI work as well? Or I need to wait for the 19.10 update?
i would like to clone my whole hdd (750gb – only 200gb with any data) contaning ubuntu and all data to ssd (500gb) and replace those drives so it works a bit faster. It there a easy way to do it with some kind of software like GNOME? Cheers, woxxu
