Trying to get it installed, but I keep getting an error.

Is there a video tutorial on how to upgrade?

This isn't the best thread for getting technical help, not to mention it's off-topic.

Create a thread in the Bitcoin Technical Support board, and provide more details about your system, current configuration, intentions, and issues.

Hi, Please help. I'm running Ubuntu 16.04 and have Bitcoin core 18 installed. When I installed BC 21 it created a separate folder and no executable icon on my desktop. The only way to run BC 21 now is from the terminal, it opens and has my wallet and all info but that is stored in the previous versions folder. All other versions merged the upgrade, so is there a way to merge the two.  I tried to follow the OP instructions but I do not have bitcoin-qt or bitcoind in my BC 18 folder and not sure where they are. Oh and the Bitcoin icon on my desktop only executes the BC 18 version. Also, can I continue to use BC 18 without any real issues?

1. do

find / -name bitcoin-qt

in a terminal


2. then

find / -name bitcoin*.desktop


3. open the .desktop files in text editor. read them.


new bitcoin-qt (0.21.1) will have a newer date.

what you want is the Exec= line in your .desktop file to point to the new bitcoin-qt, not the old one


if you installed the old bitcoin-qt (0.18 or whatever) or the new bitcoin-qt (0.21.1) with Snap or any of these other "easy" methods, then you've got a bigger problem. That's what you get for believing in the "easy" way

I was very much convinced with the upgrade but when I read about the warning signs, I started having second thoughts. Isn’t there any way by which we can avoid these?

which warnings?

there is only 1 warning I know of: the "Unknown version bits activated" warning if you are using older versions of Bitcoin Core. This means that there is a new soft fork activated on the network, and that the older software doesn't recognize it.


only Bitcoin 0.21.1+ recognizes the taproot fork, which is the unknown fork being detected by old Bitcoin software.

So, when you tried to renew the certificate, they revoked it retroactively due to their new national-registration policy?
They never gave a reason, so I have no idea.

There was also another annoying thing that happened when I tried to renew the certificate: Sectigo revoked the one that was about to expire, with a backdated revocation. This means that any release that was code signed with that certificate now shows even scarier warnings when you try to install it. This affects 4 released versions and we will be re-releasing those versions once we get the new certificate.

So, when you tried to renew the certificate, they revoked it retroactively due to their new national-registration policy?  Talk about salt on the wound.  It seems like they should have warned you that was going to be case when they enacted the new policy late last year. 

Thanks for the explanation (and everything else you and dev team do.)  Best of luck with the certificate.

but I'm just curious what the issue is.  Is this just a delay, or will the certificate remain unobtainable?
For past few years, we've been getting 1 year certificates around the end of March. So this year, I went to renew the certificate, but Sectigo (the CA we've been using) asked us to register the organization we use with a government. The legal entity we have been using for certificates is a Swiss Association, and those don't require government registration. But apparently the CA/B Forum (the group that sets the rules for certificates) added a new rule late last year that requires CAs to make sure that organizations are registered with governments.

So we've spent the past 2 months figuring out how to register the Association with the Swiss government, and then waiting for the registration to go through and become publicly searchable so that whatever CA we use will be able to find it. So this should just be a delay, but it might take another month or two.

We did also setup another organization, this time a LLC in the US. So this should give us a backup option in the future, as well as possibly for right now if the LLC can be fully setup before the Swiss Association is registered.

There was also another annoying thing that happened when I tried to renew the certificate: Sectigo revoked the one that was about to expire, with a backdated revocation. This means that any release that was code signed with that certificate now shows even scarier warnings when you try to install it. This affects 4 released versions and we will be re-releasing those versions once we get the new certificate.

Note that for this release, due to issues with acquiring a Windows code signing certificate, the Windows installer is not code signed. This means that there will be additional warnings when attempting to run the Windows installer.

Not that it's a big deal (signatures match the hashes, hashes match the files) but I'm just curious what the issue is.  Is this just a delay, or will the certificate remain unobtainable?

FYI, other than the extra Windows notification I had no issue updating.

0.21.1 Release Notes

Bitcoin Core version 0.21.1 is now available from:

https://bitcoincore.org/bin/bitcoin-core-0.21.1/

This minor release includes various bug fixes and performance
improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/bitcoin/bitcoin/issues

To receive security and update notifications, please subscribe to:

https://bitcoincore.org/en/list/announcements/join/

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes in some cases), then run the
installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac)
or bitcoind/bitcoin-qt (on Linux).

Upgrading directly from a version of Bitcoin Core that has reached its EOL is
possible, but it might take some time if the data directory needs to be migrated. Old
wallet versions of Bitcoin Core are generally supported.

Compatibility

Bitcoin Core is supported and extensively tested on operating systems
using the Linux kernel, macOS 10.12+, and Windows 7 and newer.  Bitcoin
Core should also work on most other Unix-like systems but is not as
frequently tested on them.  It is not recommended to use Bitcoin Core on
unsupported systems.

From Bitcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no
longer supported. Additionally, Bitcoin Core does not yet change appearance
when macOS "dark mode" is activated.

Notable changes

Taproot Soft Fork

Included in this release are the mainnet and testnet activation
parameters for the taproot soft fork (BIP341) which also adds support
for schnorr signatures (BIP340) and tapscript (BIP342).

If activated, these improvements will allow users of single-signature
scripts, multisignature scripts, and complex contracts to all use
identical-appearing commitments that enhance their privacy and the
fungibility of all bitcoins. Spenders will enjoy lower fees and the
ability to resolve many multisig scripts and complex contracts with the
same efficiency, low fees, and large anonymity set as single-sig users.
Taproot and schnorr also include efficiency improvements for full nodes
such as the ability to batch signature verification.  Together, the
improvements lay the groundwork for future potential
upgrades that may improve efficiency, privacy, and fungibility further.

Activation for taproot is being managed using a variation of BIP9
versionbits called Speedy Trial (described in BIP341). Taproot's
versionbit is bit 2, and nodes will begin tracking which blocks signal
support for taproot at the beginning of the first retarget period after
taproot’s start date of 24 April 2021.  If 90% of blocks within a
2,016-block retarget period (about two weeks) signal support for taproot
prior to the first retarget period beginning after the time of 11 August
2021, the soft fork will be locked in, and taproot will then be active
as of block 709632 (expected in early or mid November).

Should taproot not be locked in via Speedy Trial activation, it is
expected that a follow-up activation mechanism will be deployed, with
changes to address the reasons the Speedy Trial method failed.

This release includes the ability to pay taproot addresses, although
payments to such addresses are not secure until taproot activates.
It also includes the ability to relay and mine taproot transactions
after activation.  Beyond those two basic capabilities, this release
does not include any code that allows anyone to directly use taproot.
The addition of taproot-related features to Bitcoin Core's wallet is
expected in later releases once taproot activation is assured.

All users, businesses, and miners are encouraged to upgrade to this
release (or a subsequent compatible release) unless they object to
activation of taproot.  If taproot is locked in, then upgrading before
block 709632 is highly recommended to help enforce taproot's new rules
and to avoid the unlikely case of seeing falsely confirmed transactions.

Miners who want to activate Taproot should preferably use this release
to control their signaling.  The getblocktemplate RPC results will
automatically be updated to signal once the appropriate start has been
reached and continue signaling until the timeout occurs or taproot
activates.  Alternatively, miners may manually start signaling on bit 2
at any time; if taproot activates, they will need to ensure they update
their nodes before block 709632 or non-upgraded nodes could cause them to mine on
an invalid chain.  See the versionbits
FAQ
for
details.

For more information about taproot, please see the following resources:

Updated RPCs
  • Due to BIP 350
      being implemented, behavior for all RPCs that accept addresses is changed when
      a native witness version 1 (or higher) is passed. These now require a Bech32m
      encoding instead of a Bech32 one, and Bech32m encoding will be used for such
      addresses in RPC output as well. No version 1 addresses should be created
      for mainnet until consensus rules are adopted that give them meaning
      (e.g. through BIP 341).
      Once that happens, Bech32m is expected to be used for them, so this shouldn't
      affect any production systems, but may be observed on other networks where such
      addresses already have meaning (like signet).
