Package Manager Failed to prepare software

[Shampow]

I’ve tried to update my packages using the add/remove software app for months and it always fails. What should I do? Can someone help me troubleshoot this?

[brahma]

run this:
pamac update

[HowTo] Post command output and file content as formatted text

Difficulty: ★☆☆☆☆ Formatting differences Discourse – this forum’s engine – uses Markdown to format its posts, and removes “unnecessary” whitespace. Terminal commands often produce output formatted so that they are better readable by the user, taking advantage of the monospaced font used. Programming code often rely on indentation to make it more readable. Using preformatting in Markdown Markdown includes a pattern to provide preformatting when necessary.

I’ve done it for you this time.

It looks like it updated everything but it didn’t finish. It just stopped here,

[brahma]

you didnt cancel it? it downloaded the updates, and then it will run the actual updates, so wait

@Shampow

Error: Failed to prepare transaction:
could not satisfy dependencies:
- removing wxgtk-common breaks dependency 'wxgtk-common' required by wxgtk2

Please read #announcements posts and search the forum before posting.

@philm

wxWidgets 3.2 update may need manual intervention

Packages have been renamed from wxgtk- to wxwidgets-. The GTK2 frontend is no longer provided. If you have wxgtk2 installed, the upgrade will fail with:

error: failed to prepare transaction (could not satisfy dependencies) :: removing wxgtk-common breaks dependency ‘wxgtk-common’ required by wxgtk2

In such case, uninstall wxgtk2 first and then proceed with the upgrade.

@brahma

pamac update

@brahma

sudo pamac update

Pamac will prompt for elevated privileges when needed. It is not recommended to use sudo with it at all–especially when updating AUR packages.

[Shampow]

No I didn’t cancel it.
It updated 375 of the 400 updates.

[brahma]

so did it finished succesfully?

[Shampow]

For the most part, it failed to build this though

@Shampow

==> ERROR: One or more PGP signatures could not be verified!

AUR package fails to verify PGP/GPG key: “unknown public key”, “One or more PGP signatures could not be verified!”

Summary If you get llvm-5.0.1.src.tar.xz … FAILED (unknown public key 8F0871F202119294) then gpg --recv-key 8F0871F202119294 and try again. Enter the key ID as appropriate. Detail Many AUR packages contain lines to enable validating downloaded packages though the use of a PGP key. This establishes a level of trust between the software author and anyone who downloads the software - if you trust the key, and the download validates against the key, then you can trust the download.

[brahma]

and how to fix this:

cp: cannot create regular file '/var/tmp/pamac/dbs/sync/pamac_aur.db': Permission denied

thats why i suggested to run sudo with pamac

[Shampow]

I got the same error as above

[brahma]

if you run again:
pamac update
whats the ouptut?

[Yochanan]

@brahma

thats why i suggested to run sudo with pamac

Pamac already has access to /var/tmp/, using sudo should not be necessary.

I suggest creating an issue if there is not already an existing one.

[brahma]

here is the same issue
and here is a possible fix, but i dont know if its safe to remove it
